* caddytls: Support new tls.context module
This allows modules to manipulate the context passed into CertMagic's GetCertificate function, which can be useful for tracing/metrics, or other
custom logic.
This is experimental and may resolve the request of a sponsor, so we'll see how it goes!
* Derpy derp
By default Go 1.23 enables X25519Kyber768, a post-quantum key agreement
method that is enabled by default on Chrome. Go 1.23 does not expose
the CurveID, so we cannot add it by specifying it in CurvePreferences.
The reason is that X25519Kyber768 is a preliminary key agreement that
will be supplanted by X25519MLKEM768. For the moment there is value
in enabling it.
A consequence of this is that by default Caddy will enable support
for P-384 and P-521.
This PR also removes the special code to add support for X25519Kyber768
via the Cloudflare Go branch.

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.
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.
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.
* ability to specify that client cert must be present in SSL
* changed the clientauthtype to string and make room for the values supported by go as in caddy1
* renamed the config parameter according to review comments and added documentation on allowed values
* missed a reference
* Minor cleanup; docs enhancements

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.
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).

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.
Making them pointers makes for cleaner JSON when adapting configs, if
the struct is empty now it will be omitted entirely.
The x/time/rate package was updated to support changing the burst, so
we've incorporated that here and removed a TODO.

Along with several other changes, such as renaming caddyhttp.ServerRoute
to caddyhttp.Route, exporting some types that were not exported before,
and tweaking the caddytls TLS values to be more consistent.
Notably, we also now disable automatic cert management for names which
already have a cert (manually) loaded into the cache. These names no
longer need to be specified in the "skip_certificates" field of the
automatic HTTPS config, because they will be skipped automatically.
