904f9fddcc tls: centralise HTTPS RR ALPN defaults and registration
Reuse shared protocol defaults instead of repeating the default HTTP protocol list, unify server name registration to carry ALPN in one experimental API and reuse the TLS default ALPN ordering for HTTPS RR publication

1fbb28720b Fix lint errors
Use VerifyConnection instead of VerifyPeerCertificate; the other 2 fixes are "meh" not really a big deal or an issue at all.

d42d39b4bc caddytls: Return errors instead of nil in client auth provisioning (#7464)
Two error returns in ClientAuthentication.provision() were
returning nil instead of the actual error, silently swallowing
failures when converting PEM files to DER and when provisioning
the CA pool. This could cause mTLS client authentication to
silently fall back to the system trust store, accepting any
client certificate signed by a public CA instead of restricting
to the configured trust anchors.

dcbf38d0b3 tls: use Go default kex for the moment that include PQC (#6542)
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.

b814c0af9c 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.

2f59467ac3 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.

6ca5828221 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.
