* httpcaddyfile: Skip some logic if auto_https off

* Try removing this check altogether...

* Refine test timeouts slightly, sigh

* caddyhttp: Assume udp for unrecognized network type

Seems like the reasonable thing to do if a plugin registers its own
network type.

e43b6d8178 core: Variadic Context.Logger(); soft deprecation
Ideally I'd just remove the parameter to caddy.Context.Logger(), but
this would break most Caddy plugins.

Instead, I'm making it variadic and marking it as partially deprecated.
In the future, I might completely remove the parameter once most
plugins have updated.

httpcaddyfile: Add a couple more placeholder shortcuts (#5015)
This adds:
- `{file.*}` -> `{http.request.uri.path.file.*}`
- `{file_match.*}` -> `{http.matchers.file.*}`

This is a follow-up to #4993 which introduces the new URI file placeholders, and a shortcut for using `file` matcher output.

For example, where the `try_files` directive is a shortcut for this:

```
@try_files file <files...>
rewrite @try_files {http.matchers.file.relative}
```

It could instead be:
```
@try_files file <files...>
rewrite @try_files {file_match.relative}
```

httpcaddyfile: Detect ambiguous site definitions (fix #4635)
Previously, our "duplicate key in server block" logic was flawed because
it did not account for the site's bind address. We defer this check to
when the listener addresses have been assigned, but before we commit
a server block to its listener.

Also refined how network address parsing and joining works, which was
necessary for a less convoluted fix.

httpcaddyfile: Fix #4640 (auto-HTTPS edgecase) (#4661)
Guh, this is complicated.

Fixes #4640

This also follows up on #4398 (reverting it) which made a change that technically worked, but was incorrect. It changed the condition in `hostsFromKeysNotHTTP` from `&&` to `||`, but then the function no longer did what its name said it would do, and it would return hosts even if they were marked with `http://`, if they used a non-HTTP port. That wasn't the intent of it. The test added in there was kept though, because it is a valid usecase.

The actual fix is to check _earlier_ whether all the addresses explicitly have `http://`, and if so we can short circuit and skip considering the rest.

reverseproxy: copy_response and copy_response_headers for handle_response routes (#4391)
* reverseproxy: New `copy_response` handler for `handle_response` routes

Followup to #4298 and #4388.

This adds a new `copy_response` handler which may only be used in `reverse_proxy`'s `handle_response` routes, which can be used to actually copy the proxy response downstream. 

Previously, if `handle_response` was used (with routes, not the status code mode), it was impossible to use the upstream's response body at all, because we would always close the body, expecting the routes to write a new body from scratch.

To implement this, I had to refactor `h.reverseProxy()` to move all the code that came after the `HandleResponse` loop into a new function. This new function `h.finalizeResponse()` takes care of preparing the response by removing extra headers, dealing with trailers, then copying the headers and body downstream.

Since basically what we want `copy_response` to do is invoke `h.finalizeResponse()` at a configurable point in time, we need to pass down the proxy handler, the response, and some other state via a new `req.WithContext(ctx)`. Wrapping a new context is pretty much the only way we have to jump a few layers in the HTTP middleware chain and let a handler pick up this information. Feels a bit dirty, but it works.

Also fixed a bug with the `http.reverse_proxy.upstream.duration` placeholder, it always had the same duration as `http.reverse_proxy.upstream.latency`, but the former was meant to be the time taken for the roundtrip _plus_ copying/writing the response.

* Delete the "Content-Length" header if we aren't copying

Fixes a bug where the Content-Length will mismatch the actual bytes written if we skipped copying the response, so we get a message like this when using curl:

```
curl: (18) transfer closed with 18 bytes remaining to read
```

To replicate:

```
{
	admin off
	debug
}

:8881 {
	reverse_proxy 127.0.0.1:8882 {
		@200 status 200
		handle_response @200 {
			header Foo bar
		}
	}
}

:8882 {
	header Content-Type application/json
	respond `{"hello": "world"}` 200
}
```

* Implement `copy_response_headers`, with include/exclude list support

* Apply suggestions from code review

caddytls: dns_challenge_override_domain for challenge delegation (#4596)
* Add a override_domain option to allow DNS chanllenge delegation

CNAME can be used to delegate answering the chanllenge to another DNS
zone. One usage is to reduce the exposure of the DNS credential [1].
Based on the discussion in caddy/certmagic#160, we are adding an option
to allow the user explicitly specify the domain to delegate, instead of
following the CNAME chain.

This needs caddy/certmagic#160.

* rename override_domain to dns_challenge_override_domain

* Update CertMagic; fix spelling

caddytls: Support external certificate Managers (like Tailscale) (#4541)
Huge thank-you to Tailscale (https://tailscale.com) for making this change possible!
This is a great feature for Caddy and Tailscale is a great fit for a standard implementation.

* caddytls: GetCertificate modules; Tailscale

* Caddyfile support for get_certificate

Also fix AP provisioning in case of empty subject list (persist loaded
module on struct, much like Issuers, to surive reprovisioning).

And implement start of HTTP cert getter, still WIP.

* Update modules/caddytls/automation.go

Co-authored-by: Francis Lavoie <lavofr@gmail.com>

* Use tsclient package, check status for name

* Implement HTTP cert getter

And use reuse CertMagic's PEM functions for private keys.

* Remove cache option from Tailscale getter

Tailscale does its own caching and we don't need the added complexity...
for now, at least.

* Several updates

- Option to disable cert automation in auto HTTPS
- Support multiple cert managers
- Remove cache feature from cert manager modules
- Minor improvements to auto HTTPS logging

* Run go mod tidy

* Try to get certificates from Tailscale implicitly

Only for domains ending in .ts.net.

I think this is really cool!

httpcaddyfile: Fix incorrect handling of IPv6 bind addresses (#4532)
The `net.JoinHostPort()` function has some naiive logic for handling IPv6, it just checks if the host part has a `:` and if so it wraps the host part with `[ ]` but this causes our network type prefix to get wrapped as well, which is invalid for `caddy.NetworkAddress`. Instead, we can just concatenate the host and port manually here to avoid this side-effect.

httpcaddyfile: Reorder some directives (#4311)
We realized we made some mistakes with the directive ordering, so we're making some minor adjustments.

`abort` and `error` don't really make sense to be after other handler directives, because you would expect to be able to "fail-fast" and throw an error before falling through to some `file_server` or `respond` typically. So we're moving them up to just before `respond`, i.e. before the common handler directives. 

This is also more consistent with our existing examples in the docs, which actually didn't work due to the directive ordering. See https://caddyserver.com/docs/caddyfile/directives/error#examples

Also, `push` doesn't quite make sense to be after `handle`/`route`, since its job is to read from response headers to push additional resources if necessary, and `handle`/`route` may be terminal so push would not be reached if it was declared outside those. And also, it would make sense to be _before_ `templates` because a template _could_ add a `Link` header to the response dynamically.

caddyfile: Better error message for missing site block braces (#4301)
Some new users mistakenly try to define two sites without braces around each. Doing this can yield a confusing error message saying that their site address is an "unknown directive".

We can do better by keeping track of whether the current site block was parsed with or without a brace, then changing the error message later based on that.

For example, now this invalid config:

```
foo.example.com
respond "foo"

bar.example.com
respond "bar"
```

Will yield this error message:

```
$ caddy adapt
2021/08/22 19:21:31.028 INFO    using adjacent Caddyfile
adapt: Caddyfile:4: unrecognized directive: bar.example.com
Did you mean to define a second site? If so, you must use curly braces around each site to separate their configurations.

caddyfile: Error on invalid site addresses containing comma (#4302)
Some users forget to use a comma between their site addresses. This is invalid (commas aren't a valid character in domains) and later parts of the code like certificate automation will try to use this otherwise, which doesn't make sense. Best to error as early as possible.

httpcaddyfile: Add shortcut for proxy hostport placeholder (#4263)
* httpcaddyfile: Add shortcut for proxy hostport placeholder

I've noticed that it's a pretty common pattern to write a proxy like this, when needing to proxy over HTTPS:

```
reverse_proxy https://example.com {
	header_up Host {http.reverse_proxy.upstream.hostport}
}
```

I find it pretty hard to remember the exact placeholder to use for this, and I continually need to refer to the docs when I need it. I think a simple fix for this is to add another Caddyfile placeholder for this one to shorten it:

```
reverse_proxy https://example.com {
	header_up Host {proxy_hostport}
}
```

httpcaddyfile: Don't put localhost in public APs (fix #4220)
If an email is specified in global options, a site called 'localhost' shouldn't be bunched together with public DNS names in the automation policies, which get the default, public-CA issuers. Fix old test that did this.

I also noticed that these two:

    localhost {
    }
    example.com {
    }

and

    localhost, example.com {
    }

produce slightly different TLS automation policies. The former is what the new test case covers, and we have logic that removes the empty automation policy for localhost so that auto-HTTPS can implicitly create one. (We prefer that whenever possible.) But the latter case produces two automation policies, with the second one being for localhost, with an explicit internal issuer. It's not wrong, just more explicit than it needs to be.

I'd really like to completely rewrite the code from scratch that generates automation policies, hopefully there is a simpler, more correct algorithm.

caddyfile: Add parse error on site address with trailing { (#4163)
* caddyfile: Add parse error on site address in `{`

This is an incredibly common mistake made by users, so we should catch it earlier in the parser and give a more friendly message. Often it ends up adapting but with mistakes, or erroring out later due to other site addresses being read as directives.

There's not really ever a situation where a lone '{' is valid at the end of a site address (but I suppose there are edgecases where the user wants to use a path matcher where it ends specifically in `{`, but... why?), so this should be fine.

caddyconfig: add global option for configuring loggers (#4028)
This change is aimed at enhancing the logging module within the
Caddyfile directive to allow users to configure logs other than the HTTP
access log stream, which is the current capability of the Caddyfile [1].
The intent here is to leverage the same syntax as the server log
directive at a global level, so that similar customizations can be added
without needing to resort to a JSON-based configuration.

Discussion for this approach happened in the referenced issue.

admin: Identity management, remote admin, config loaders (#3994)
This commits dds 3 separate, but very related features:

1. Automated server identity management

How do you know you're connecting to the server you think you are? How do you know the server connecting to you is the server instance you think it is? Mutually-authenticated TLS (mTLS) answers both of these questions. Using TLS to authenticate requires a public/private key pair (and the peer must trust the certificate you present to it).

Fortunately, Caddy is really good at managing certificates by now. We tap into that power to make it possible for Caddy to obtain and renew its own identity credentials, or in other words, a certificate that can be used for both server verification when clients connect to it, and client verification when it connects to other servers. Its associated private key is essentially its identity, and TLS takes care of possession proofs.

This configuration is simply a list of identifiers and an optional list of custom certificate issuers. Identifiers are things like IP addresses or DNS names that can be used to access the Caddy instance. The default issuers are ZeroSSL and Let's Encrypt, but these are public CAs, so they won't issue certs for private identifiers. Caddy will simply manage credentials for these, which other parts of Caddy can use, for example: remote administration or dynamic config loading (described below).

2. Remote administration over secure connection

This feature adds generic remote admin functionality that is safe to expose on a public interface.

- The "remote" (or "secure") endpoint is optional. It does not affect the standard/local/plaintext endpoint.
- It's the same as the [API endpoint on localhost:2019](https://caddyserver.com/docs/api), but over TLS.
- TLS cannot be disabled on this endpoint.
- TLS mutual auth is required, and cannot be disabled.
- The server's certificate _must_ be obtained and renewed via automated means, such as ACME. It cannot be manually loaded.
- The TLS server takes care of verifying the client.
- The admin handler takes care of application-layer permissions (methods and paths that each client is allowed to use).\
- Sensible defaults are still WIP.
- Config fields subject to change/renaming.

3. Dyanmic config loading at startup

Since this feature was planned in tandem with remote admin, and depends on its changes, I am combining them into one PR.

Dynamic config loading is where you tell Caddy how to load its config, and then it loads and runs that. First, it will load the config you give it (and persist that so it can be optionally resumed later). Then, it will try pulling its _actual_ config using the module you've specified (dynamically loaded configs are _not_ persisted to storage, since resuming them doesn't make sense).

This PR comes with a standard config loader module called `caddy.config_loaders.http`.

Caddyfile config for all of this can probably be added later.

COMMITS:

* admin: Secure socket for remote management

Functional, but still WIP.

Optional secure socket for the admin endpoint is designed
for remote management, i.e. to be exposed on a public
port. It enforces TLS mutual authentication which cannot
be disabled. The default port for this is :2021. The server
certificate cannot be specified manually, it MUST be
obtained from a certificate issuer (i.e. ACME).

More polish and sensible defaults are still in development.

Also cleaned up and consolidated the code related to
quitting the process.

* Happy lint

* Implement dynamic config loading; HTTP config loader module

This allows Caddy to load a dynamic config when it starts.

Dynamically-loaded configs are intentionally not persisted to storage.

Includes an implementation of the standard config loader, HTTPLoader.
Can be used to download configs over HTTP(S).

* Refactor and cleanup; prevent recursive config pulls

Identity management is now separated from remote administration.

There is no need to enable remote administration if all you want is identity
management, but you will need to configure identity management
if you want remote administration.

* Fix lint warnings

* Rename identities->identifiers for consistency

caddytest: Update Caddyfile tests for formatting, HTTP-only blocks
Previous commit improved the Caddyfile adapter so it doesn't unnecessarily add names to "skip" in "auto_https" when the server is already HTTP-only.

This commit updates the tests to reflect that change, while also fixing the Caddyfile formatting in many of the tests.

We also print the line number of the divergence between input and formatted version in Caddyfile adapt warnings - very useful for finding initial formatting problems.

httpcaddyfile: Support repeated use of cert_issuer global option
This changes the signature of UnmarshalGlobalFunc but this is probably OK since it's only used by this repo as far as we know.

We need this change in order to "remember" the previous value in case a global option appears more than once, which is now a possibility with the cert_issuer option since Caddy now supports multiple issuers in the order defined by the user.

Bonus: the issuer subdirective of tls now supports one-liner for "acme" when all you need to set is the directory:

issuer acme <dir>

headers: Support default header values in Caddyfile with '?' (#3807)
* implement default values for header directive

closes #3804

* remove `set_default` header op and rely on "require" handler instead

This has the following advantages over the previous attempt:

- It does not introduce a new operation for headers, but rather nicely
  extends over an existing feature in the header handler.
- It removes the need to specify the header as "deferred" because it is
  already implicitely deferred by the use of the require handler. This
  should be less confusing to the user.

* add integration test for header directive in caddyfile

* bubble up errors when parsing caddyfile header directive

* don't export unnecessarily and don't canonicalize headers unnecessarily

* fix response headers not passed in blocks

* caddyfile: fix clash when using default header in block

Each header is now set in a separate handler so that it doesn't clash
with other headers set/added/deleted in the same block.

* caddyhttp: New idle_timeout default of 5m

* reverseproxy: fix random hangs on http/2 requests with server push (#3875)

httpcaddyfile: Revise automation policy generation (#3824)
* httpcaddyfile: Revise automation policy generation

This should fix a frustrating edge case where wildcard subjects are
used, which potentially get shadowed by more specific versions of
themselves; see the new tests for an example. This change is motivated
by an actual customer requirement.

Although all the tests pass, this logic is incredibly complex and
nuanced, and I'm worried it is not correct. But it took me about 4 days
to get this far on a solution. I did my best.

httpcaddyfile: Improve AP logic with OnDemand
We have users that have site blocks like *.*.tld with on-demand TLS
enabled. While *.*.tld does not qualify for a publicly-trusted cert due
to its wildcards, On-Demand TLS does not actually obtain a cert with
those wildcards, since it uses the actual hostname on the handshake.

This improves on that logic, but I am still not 100% satisfied with the
result since I think we need to also check if another site block is more
specific, like foo.example.tld, which might not have on-demand TLS
enabled, and make sure an automation policy gets created before the
more general policy with on-demand...

httpcaddyfile: Properly record whether we added catch-all conn policy
We recently introduced `if !cp.SettingsEmpty()` which conditionally
adds the connection policy to the list. If the condition evaluates to
false, the policy wouldn't actually be added, even if
hasCatchAllTLSConnPolicy was set to true on the previous line.

Now we set that variable in accordance with whether we actually add
the policy.

While debugging this I noticed that catch-all policies added early in
that loop (i.e. not at the end if we later determine we need one) are
not always at the end of the list. They should be, though, since they
are selected by which one matches first, and having a catch-all first
would nullify any more specific ones later in the list. So I added a
sort in consolidateConnPolicies to take care of that.

Should fix #3670 and
https://caddy.community/t/combining-on-demand-tls-with-custom-ssl-certs-doesnt-seem-to-work-in-2-1-1/9719
but I won't know for sure until somebody verifies it, since at least in
the GitHub issue there is not yet enough information (the configs are
redacted).

caddytls: Add support for ZeroSSL; add Caddyfile support for issuers (#3633)
* caddytls: Add support for ZeroSSL; add Caddyfile support for issuers

Configuring issuers explicitly in a Caddyfile is not easily compatible
with existing ACME-specific parameters such as email or acme_ca which
infer the kind of issuer it creates (this is complicated now because
the ZeroSSL issuer wraps the ACME issuer)... oh well, we can revisit
that later if we need to.

New Caddyfile global option:

    {
        cert_issuer <name> ...
    }

Or, alternatively, as a tls subdirective:

    tls {
        issuer <name> ...
    }

For example, to use ZeroSSL with an API key:

    {
        cert_issuser zerossl API_KEY
    }

For now, that still uses ZeroSSL's ACME endpoint; it fetches EAB
credentials for you. You can also provide the EAB credentials directly
just like any other ACME endpoint:

    {
        cert_issuer acme {
            eab KEY_ID MAC_KEY
        }
    }

All these examples use the new global option (or tls subdirective). You
can still use traditional/existing options with ZeroSSL, since it's
just another ACME endpoint:

    {
        acme_ca  https://acme.zerossl.com/v2/DV90
        acme_eab KEY_ID MAC_KEY
    }

That's all there is to it. You just can't mix-and-match acme_* options
with cert_issuer, because it becomes confusing/ambiguous/complicated to
merge the settings.

* Fix broken test

This test was asserting buggy behavior, oops - glad this branch both
discovers and fixes the bug at the same time!

* Fix broken test (post-merge)

* Update modules/caddytls/acmeissuer.go

Fix godoc comment

Co-authored-by: Francis Lavoie <lavofr@gmail.com>

* Add support for ZeroSSL's EAB-by-email endpoint

Also transform the ACMEIssuer into ZeroSSLIssuer implicitly if set to
the ZeroSSL endpoint without EAB (the ZeroSSLIssuer is needed to
generate EAB if not already provided); this is now possible with either
an API key or an email address.

* go.mod: Use latest certmagic, acmez, and x/net

* Wrap underlying logic rather than repeating it

Oops, duh

* Form-encode email info into request body for EAB endpoint
