core: Don't return error on RegisterModule() and RegisterAdapter()
These functions are called at init-time, and their inputs are hard-coded
so there are no environmental or user factors that could make it fail
or succeed; the error return values are often ignored, and when they're
not, they are usually a fatal error anyway. To ensure that a programmer
mistake is not missed, we now panic instead.

Last breaking change 🤞

httpcaddyfile: Put root directive first, before redir and rewrite
See https://caddy.community/t/v2-match-any-path-but-files/7326/8?u=matt

If rewrites (or redirects, for that matter) match on file existence,
the file matcher would need to know the root of the site.

Making this change implies that root directives that depend on rewritten
URIs will not work as expected. However, I think this is very uncommon,
and am not sure I have ever seen that. Usually, dynamic roots are based
on host, not paths or query strings.

I suspect that rewrites based on file existence will be more common than
roots based on rewritten URIs, so I am moving root to be the first in
the list.

Users can always override this ordering with the 'order' global option.

b8cba62643 Refactor for CertMagic v0.10; prepare for PKI app
This is a breaking change primarily in two areas:
 - Storage paths for certificates have changed
 - Slight changes to JSON config parameters

Huge improvements in this commit, to be detailed more in
the release notes.

The upcoming PKI app will be powered by Smallstep libraries.

Expose TLS placeholders (#2982)
* caddytls: Add CipherSuiteName and ProtocolName functions

The cipher_suites.go file is derived from a commit to the Go master
branch that's slated for Go 1.14.  Once Go 1.14 is released, this file
can be removed.

* caddyhttp: Use commonLogEmptyValue in common_log replacer

* caddyhttp: Add TLS placeholders

* caddytls: update unsupportedProtocols

Don't export unsupportedProtocols and update its godoc to mention that
it's used for logging only.

* caddyhttp: simplify getRegTLSReplacement signature

getRegTLSReplacement should receive a string instead of a pointer.

* caddyhttp: Remove http.request.tls.client.cert replacer

The previous behavior of printing the raw certificate bytes was ported
from Caddy 1, but the usefulness of that approach is suspect.  Remove
the client cert replacer from v2 until a use case is presented.

* caddyhttp: Use tls.CipherSuiteName from Go 1.14

Remove ported version of CipherSuiteName in the process.

caddyhttp: Add handler for unhandled errors in errorChain (#3063)
* Add handler for unhandled errors in errorChain

Currently, when an error chain is defined, the default error handler is
bypassed entirely - even if the error chain doesn't handle every error.
This results in pages returning a blank 200 OK page.

For instance, it's possible for an error chain to match on the error
status code and only handle a certain subtype of errors (like 403s). In
this case, we'd want any other errors to still go through the default
handler and return an empty page with the status code.

This PR changes the "suffix handler" passed to errorChain.Compile to
set the status code of the response to the error status code.

Fixes #3053

* Move the errorHandlerChain middleware to variable

* Style fix

http: Split 2-phase auto-HTTPS into 3 phases
This is necessary to avoid a race for sockets. Both the HTTP servers and
CertMagic solvers will try to bind the HTTP/HTTPS ports, but we need to
make sure that our HTTP servers bind first. This is kind of a new thing
now that management is async in Caddy 2.

Also update to CertMagic 0.9.2, which fixes some async use cases at
scale.

http: Refactor automatic HTTPS (fixes #2972)
This splits automatic HTTPS into two phases. The first provisions the
route matchers and uses them to build the domain set and configure
auto HTTP->HTTPS redirects. This happens before the rest of the
provisioning does.

The second phase takes place at the beginning of the app start. It
attaches pointers to the tls app to each server, and begins certificate
management for the domains that were found in the first phase.

http: Change routes to sequential matcher evaluation (#2967)
Previously, all matchers in a route would be evaluated before any
handlers were executed, and a composite route of the matching routes
would be created. This made rewrites especially tricky, since the only
way to defer later matchers' evaluation was to wrap them in a subroute,
or to invoke a "rehandle" which often caused bugs.

Instead, this new sequential design evaluates each route's matchers then
its handlers in lock-step; matcher-handlers-matcher-handlers...

If the first matching route consists of a rewrite, then the second route
will be evaluated against the rewritten request, rather than the original
one, and so on.

This should do away with any need for rehandling.

I've also taken this opportunity to avoid adding new values to the
request context in the handler chain, as this creates a copy of the
Request struct, which may possibly lead to bugs like it has in the past
(see PR #1542, PR #1481, and maybe issue #2463). We now add all the
expected context values in the top-level handler at the server, then
any new values can be added to the variable table via the VarsCtxKey
context key, or just the GetVar/SetVar functions. In particular, we are
using this facility to convey dial information in the reverse proxy.

Had to be careful in one place as the middleware compilation logic has
changed, and moved a bit. We no longer compile a middleware chain per-
request; instead, we can compile it at provision-time, and defer only the
evaluation of matchers to request-time, which should slightly improve
performance. Doing this, however, we take advantage of multiple function
closures, and we also changed the use of HandlerFunc (function pointer)
to Handler (interface)... this led to a situation where, if we aren't
careful, allows one request routed a certain way to permanently change
the "next" handler for all/most other requests! We avoid this by making
a copy of the interface value (which is a lightweight pointer copy) and
using exclusively that within our wrapped handlers. This way, the
original stack frame is preserved in a "read-only" fashion. The comments
in the code describe this phenomenon.

This may very well be a breaking change for some configurations, however
I do not expect it to impact many people. I will make it clear in the
release notes that this change has occurred.

http: Enable TLS for servers listening only on HTTPS port
It seems silly to have to add a single, empty TLS connection policy to
a server to enable TLS when it's only listening on the HTTPS port. We
now do this for the user as part of automatic HTTPS (thus, it can be
disabled / overridden).

v2: Module documentation; refactor LoadModule(); new caddy struct tags (#2924)
This commit goes a long way toward making automated documentation of
Caddy config and Caddy modules possible. It's a broad, sweeping change,
but mostly internal. It allows us to automatically generate docs for all
Caddy modules (including future third-party ones) and make them viewable
on a web page; it also doubles as godoc comments.

As such, this commit makes significant progress in migrating the docs
from our temporary wiki page toward our new website which is still under
construction.

With this change, all host modules will use ctx.LoadModule() and pass in
both the struct pointer and the field name as a string. This allows the
reflect package to read the struct tag from that field so that it can
get the necessary information like the module namespace and the inline
key.

This has the nice side-effect of unifying the code and documentation. It
also simplifies module loading, and handles several variations on field
types for raw module fields (i.e. variations on json.RawMessage, such as
arrays and maps).

I also renamed ModuleInfo.Name -> ModuleInfo.ID, to make it clear that
the ID is the "full name" which includes both the module namespace and
the name. This clarity is helpful when describing module hierarchy.

As of this change, Caddy modules are no longer an experimental design.
I think the architecture is good enough to go forward.
