reverseproxy: Improve hostByHashing distribution (#5229)
* If upstreams are all using same host but with different ports
ie:
foobar:4001
foobar:4002
foobar:4003
...
Because fnv-1a has not a good enough avalanche effect
Then the hostByHashing result is not well balanced over
all upstreams

As last byte FNV input tend to affect few bits, the idea is to change
the concatenation order between the key and the upstream strings
So the upstream last byte have more impact on hash diffusion

logging: Better console encoder defaults (#5109)
This is something that has bothered me for a while, so I figured I'd do something about it now since I'm playing in the logging code lately.

The `console` encoder doesn't actually match the defaults that zap's default logger uses. This makes it match better with the rest of the logs when using the `console` encoder alongside somekind of filter, which requires you to configure an encoder to wrap.

fileserver: better dark mode visited link contrast (#5105)
PR #4066 added a dark color scheme to the file_server browse template.
PR #4356 later set the links for the `:visited` pseudo-class, but did
not set anything for the dark mode, resulting in poor contrast. I
selected some new colors by feel.

This commit also adds an `a:visited:hover` for both, to go along with
the normal blue hover colors.

map: Remove infinite recursion check (#5094)
It was not accurate. Placeholders could be used in outputs that are
defined in the same mapping as long as that placeholder does not do the
same.

A more general solution would be to detect it at run-time in the
replacer directly, but that's a bit tedious
and will require allocations I think.

A better implementation of this check could still be done, but I don't
know if it would always be accurate. Could be a "best-effort" thing?
But I've also never heard of an actual case where someone configured
infinite recursion...

core: Refactor and improve listener logic (#5089)
* core: Refactor, improve listener logic

Deprecate:
- caddy.Listen
- caddy.ListenTimeout
- caddy.ListenPacket

Prefer caddy.NetworkAddress.Listen() instead.

Change:
- caddy.ListenQUIC (hopefully to remove later)
- caddy.ListenerFunc signature (add context and ListenConfig)

- Don't emit Alt-Svc header advertising h3 over HTTP/3

- Use quic.ListenEarly instead of quic.ListenEarlyAddr; this gives us
more flexibility (e.g. possibility of HTTP/3 over UDS) but also
introduces a new issue:
https://github.com/lucas-clemente/quic-go/issues/3560#issuecomment-1258959608

Simultaneously shut down all HTTP servers, rather than one at a time.

In practice there usually won't be more than 1 that lingers. But this
code ensures that they all Shutdown() in their own goroutine
and then we wait for them at the end (if exiting).

We also wait for them to start up so we can be fairly confident the
shutdowns have begun; i.e. old servers no longer
accepting new connections.

caddyhttp: Accept placeholders in vars matcher key
Until now, the vars matcher has unintentionally lacked parity with the
map directive: the destination placeholders of the map directive would
be expressed as placeholders, i.e. {foo}. But the vars matcher would
not use { }: vars foo value

This looked weird, and was confusing, since it implied that the key
could be dynamic, which doesn't seem helpful here.

I think this is a proper bug fix, since we're not used to accessing
placeholders literally without { } in the Caddyfile.

3aabbc49a2 caddytls: Log error if ask request fails
Errors returned from the DecisionFunc (whether to get a cert on-demand)
are used as a signal whether to allow a cert or not; *any* error
will forbid cert issuance.

We bubble up the error all the way to the caller, but that caller is the
Go standard library which might gobble it up.
Now we explicitly log connection errors so sysadmins can
ensure their ask endpoints are working.

Thanks to our sponsor AppCove for reporting this!

fileserver: Support virtual file systems (#4909)
* fileserver: Support virtual file systems (close #3720)

This change replaces the hard-coded use of os.Open() and os.Stat() with
the use of the new (Go 1.16) io/fs APIs, enabling virtual file systems.
It introduces a new module namespace, caddy.fs, for such file systems.

Also improve documentation for the file server. I realized it was one of
the first modules written for Caddy 2, and the docs hadn't really been
updated since!

* Virtualize FS for file matcher; minor tweaks

* Fix tests and rename dirFS -> osFS

(Since we do not use a root directory, it is dynamic.)

forwardauth: Fix case when copy_headers is omitted (#4856)
See https://caddy.community/t/using-forward-auth-and-writing-my-own-authenticator-in-php/16410, apparently it didn't work when `copy_headers` wasn't used. This is because we were skipping adding a handler to the routes in the "good response handler", but this causes the logic in `reverseproxy.go` to ignore the response handler since it's empty. Instead, we can just always put in the `header` handler, even with an empty `Set` operation, it's just a no-op, but it fixes that condition in the proxy code.

reverseproxy: api: Remove misleading 'healthy' value
In v2.5.0, upstream health was fixed such that whether an upstream is
considered healthy or not is mostly up to each individual handler's
config. Since "healthy" is an opinion, it is not a global value.

I unintentionally left in the "healthy" field in the API endpoint for
checking upstreams, and it is now misleading (see #4792).

However, num_requests and fails remains, so health can be determined by
the API client, rather than having it be opaquely (and unhelpfully)
determined for the client.

If we do restore this value later on, it'd need to be replicated once
per reverse_proxy handler according to their individual configs.

reverseproxy: Improve hashing LB policies with HRW (#4724)
* reverseproxy: Improve hashing LB policies with HRW

Previously, if a list of upstreams changed, hash-based LB policies
would be greatly affected because the hash relied on the position of
upstreams in the pool. Highest Random Weight or "rendezvous" hashing
is apparently robust to pool changes. It runs in O(n) instead of
O(log n), but n is very small usually.

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!

caddyhttp: Fix test when /tmp/etc already exists (#4544)
The TestFileListing test in tplcontext_test has one test that verifies
if directory traversal is not happening. The context root is set to
'/tmp' and then it tries to open '../../../../../etc', which gets
normalized to '/tmp/etc'.

The test then expects an error to be returned, assuming that '/tmp/etc'
does not exist on the system. When it does exist, it results in a test
failure:

```
--- FAIL: TestFileListing (0.00s)
    tplcontext_test.go:422: Test 4: Expected error but had none
    FAIL
    FAIL
    github.com/caddyserver/caddy/v2/modules/caddyhttp/templates	0.042s
```

Instead of using '/tmp' as root, use a dedicated directory created with
`os.MkdirTemp()` instead. That way, we know that the directory is empty.
