* core: Apply SO_REUSEPORT to UDP sockets
For some reason, 10 months ago when I implemented SO_REUSEPORT
for TCP, I didn't realize, or forgot, that it can be used for UDP too. It is a
much better solution than using deadline hacks to reuse a socket, at
least for TCP.
Then https://github.com/mholt/caddy-l4/issues/132 was posted,
in which we see that UDP servers never actually stopped when the
L4 app was stopped. I verified this using this command:
$ nc -u 127.0.0.1 55353
combined with POSTing configs to the /load admin endpoint (which
alternated between an echo server and a proxy server so I could tell
which config was being used).
I refactored the code to use SO_REUSEPORT for UDP, but of course
we still need graceful reloads on all platforms, not just Unix, so I
also implemented a deadline hack similar to what we used for
TCP before. That implementation for TCP was not perfect, possibly
having a logical (not data) race condition; but for UDP so far it
seems to be working. Verified the same way I verified that SO_REUSEPORT
works.
I think this code is slightly cleaner and I'm fairly confident this code
is effective.

Fixes a bug where the following Caddyfile
```Caddyfile
{
admin unix/admin.sock|0660
}
```
and `caddy reload --config Caddyfile`
would throw the following error instead of reloading it:
```
INFO using provided configuration {"config_file": "Caddyfile", "config_adapter": ""}
Error: sending configuration to instance: performing request: Post "http://127.0.0.1/load": dial unix admin.sock|0660: connect: no such file or directory
[ERROR] exit status 1
```

This bug also affected `caddy start` and `caddy stop`.

* core: Add optional unix socket file permissions
This commit also changes the default unix socket file permissions to `u=w,g=,o=` (octal: `0200`).
It used to default to the shell's umask (usually `u=rwx,g=rx,o=rx`, octal: `0755`).
`/run/caddy.sock` -> `/run/caddy.sock` with `0200` default perms
`/run/caddy.sock|0222` -> `/run/caddy.sock` with `0222` perms
`|` instead of `:` is used as a separator, to account for the `:` in Windows drive letters (e.g. `C:\absolute\path.sock`)
Fun fact:
The old unix(7) man page (pre Jun 2016) stated a socket needs both read and write perms.
Turns out, only write perms are needed.
Corrected in 7578ea2f85
Despite this, most implementations still default to read+write to this date.
* Add cases with Windows paths to test
* Require write perms for the owning user
* fix http3 outdated certificates after config reload
* delegate quic tls GetConfigForClient to another struct.
* change type and method names
fix lint

Test 4 fails because it produces "[[::1]]:80" instead of "[::1]:80"

* add new tests
Reported on commit e3e8aabbcf
Abused this change in some bash for loops to rapidly reload config
while making requests and didn't observe any memory or resource leaks.
* 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
- Unlink unix socket before and after use
