* 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
* Appease the linter
* Keep ListenAll
* core: Refactor listeners; use SO_REUSEPORT on Unix
Just an experiment for now
* Fix lint by logging error
* TCP Keepalive configuration (#4865)
* initial attempt at TCP Keepalive configuration
