* http3: reset request streams accepted after graceful shutdown
The server needs to let the client know that these streams
are not getting processed, using the H3_REQUEST_REJECTED
error code.
* add an integration test for graceful shutdown stream cancellations
* http3: use a slice instead of a map to store active listeners
This list will be relatively short, therefore it will be
more performant to use a slice instead of a map.
No functional change expected.
* http3: rename listenerInfo to listener
* http3: update documentation for `Hijacker`
The documentation for `Hijacker` seems to be legacy from
[v0.43.0](https://github.com/quic-go/quic-go/releases/tag/v0.43.0). This
commit updates the documentation to reflect the current API use.
* http3: update documentation for `HTTPStreamer`
The documentation for `HTTPStreamer` seems to be legacy from
[v0.43.0](https://github.com/quic-go/quic-go/releases/tag/v0.43.0). This
commit updates the documentation to reflect the current API use.
The previous logic allowed for setting different ALPN
values depending on the QUIC version in use. This was
needed to set the draft ALPN value before publication of
the RFC.
Since the QUIC connection establishment process includes TLS handshake logic,
Connect and TLS handshake are called in the following order:
ConnectStart -> TLSHandshakeStart -> TLSHandshakeDone -> ConnectDone.
Notice: Wait100Continue not implemented as quic-go doesn't support handling
Expect: 100-continue.
* close connHandlingDone once only when the server is shutting down
* close underlying listeners during graceful shutdown when there is no connection
* remove connDoneOnce
* http3: rename RoundTripper to Transport
* http3: rename SingleDestinationRoundTripper to ClientConn
* http3: construct the ClientConn via Transport.NewClientConn
* send goaway when server is shutting down
* http3: track next stream ID instead of last stream ID for GOAWAYs
* refactor the graceful shutdown integration tests
* http3: improve GOAWAY frame parsing tests
* http3: simplify server graceful shutdown logic
* http3: simplify parsing of GOAWAY frames
* http3: clean up initialization of server contexts
* http3: fix race condition in graceful shutdown logic
