tls/client auth: verify first certificates in client request (#3344)
When client certificate is enabled Caddy check only last certificate from
request. When this cert is not in list of trusted leaf certificates,
connection is rejected. According to RFC TLS1.x the sender's certificate
must come first in the list.  Each following certificate must directly
certify the one preceding it.

This patch fix this problem - first certificate is checked instead of last.

httpcaddyfile: Only append TLS conn policy if it's non-empty (#3319)
This can lead to nicer, smaller JSON output for Caddyfiles like this:

	a {
		tls internal
	}
	b {
		tls foo@bar.com
	}

i.e. where the tls directive only configures automation policies, and
is merely meant to enable TLS on a server block (if it wasn't implied).
This helps keeps implicit config implicit.

Needs a little more testing to ensure it doesn't break anything
important.

httpcaddyfile, caddytls: Multiple edge case fixes; add tests
- Create two default automation policies; if the TLS app is used in
  isolation with the 'automate' certificate loader, it will now use
  an internal issuer for internal-only names, and an ACME issuer for
  all other names by default.
- If the HTTP Caddyfile adds an 'automate' loader, it now also adds an
  automation policy for any names in that loader that do not qualify
  for public certificates so that they will be issued internally. (It
  might be nice if this wasn't necessary, but the alternative is to
  either make auto-HTTPS logic way more complex by scanning the names in
  the 'automate' loader, or to have an automation policy without an
  issuer switch between default issuer based on the name being issued
  a certificate - I think I like the latter option better, right now we
  do something kind of like that but at a level above each individual
  automation policies, we do that switch only when no automation
  policies match, rather than when a policy without an issuer does
  match.)
- Set the default LoggerName rather than a LoggerNames with an empty
  host value, which is now taken literally rather than as a catch-all.
- hostsFromKeys, the function that gets a list of hosts from server
  block keys, no longer returns an empty string in its resulting slice,
  ever.

caddytls: Refactor certificate selection policies (close #1575)
Certificate selection used to be a module, but this seems unnecessary,
especially since the built-in CustomSelectionPolicy allows quite complex
selection logic on a number of fields in certs. If we need to extend
that logic, we can, but I don't think there are SO many possibilities
that we need modules.

This update also allows certificate selection to choose between multiple
matching certs based on client compatibility and makes a number of other
improvements in the default cert selection logic, both here and in the
latest CertMagic.

The hardest part of this was the conn policy consolidation logic
(Caddyfile only, of course). We have to merge connection policies that
we can easily combine, because if two certs are manually loaded in a
Caddyfile site block, that produces two connection policies, and each
cert is tagged with a different tag, meaning only the first would ever
be selected. So given the same matchers, we can merge the two, but this
required improving the Tag selection logic to support multiple tags to
choose from, hence "tags" changed to "any_tag" or "all_tags" (but we
use any_tag in our Caddyfile logic).

Combining conn policies with conflicting settings is impossible, so
that should return an error if two policies with the exact same matchers
have non-empty settings that are not the same (the one exception being
any_tag which we can merge because the logic for them is to OR them).

It was a bit complicated. It seems to work in numerous tests I've
conducted, but we'll see how it pans out in the release candidates.

tls/http: Fix auto-HTTPS logic w/rt default issuers (fixes #3164)
The comments in the code should explain the new logic thoroughly.
The basic problem for the issue was that we were overriding a catch-all
automation policy's explicitly-configured issuer with our own, for names
that we thought looked like public names. In other words, one could
configure an internal issuer for all names, but then our auto HTTPS
would create a new policy for public-looking names that uses the
default ACME issuer, because we assume public<==>ACME and
nonpublic<==>Internal, but that is not always the case. The new logic
still assumes nonpublic<==>Internal (on catch-all policies only), but
no longer assumes that public-looking names always use an ACME issuer.

Also fix a bug where HTTPPort and HTTPSPort from the HTTP app weren't
being carried through to ACME issuers properly. It required a bit of
refactoring.

caddytls: Set Issuer properly on automation policies (fix #3150)
When using the default automation policy specifically, ap.Issuer would
be nil, so we'd end up overwriting the ap.magic.Issuer's default value
(after New()) with nil; this instead sets Issuer on the template before
New() is called, and no overwriting is done.

 - Slight changes to JSON config parameters

tls: Slight adjustment to how DNS provider modules are loaded
We don't load the provider directly, because the lego provider types
aren't designed for JSON configuration and they are not implemented
as Caddy modules (there are some setup steps which a Provision call
would need to do, but they do not have Provision methods, they have
their own constructor functions that we have to wrap).

Instead of loading the challenge providers directly, the modules are
simple wrappers over the challenge providers, to facilitate the JSON
config structure and to provide a consistent experience. This also lets
us swap out the underlying challenge providers transparently if needed;
it acts as a layer of abstraction.

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.
