Enable Linux GSO in ngtcp2 QUIC. In order to recover from the
EAGAIN/EWOULDBLOCK by sendmsg with multiple packets in one GSO write,
packet buffer is now held by struct quicsocket. GSO write might fail in
runtime depending on NIC. Disable GSO if sendmsg returns EIO.
Closes#8909
Allow curl to send larger UDP datagram if Path MTU Discovery finds the
availability of larger path MTU. To make it work and not to send
fragmented packet, we need to set DF bit. That makes send(2) fail with
EMSGSIZE if UDP datagram is too large. In that case, just let it be
lost. This patch enables DF bit for Linux only.
Closes#8883
Add Curl_quic_idle which is called when no HTTP level read or write is
performed. It is a good place to handle timer expiry for QUIC transport
(.e.g, retransmission).
Closes#8698
This commit fixes HTTP/3 upload stall if upload data is larger than
H3_SEND_SIZE. Only check writability of socket if a stream is
writable to avoid busy loop when QUIC flow control window is filled
up, or upload buffer is full.
Closes#8688
Make ngtcp2+quictls correctly acknowledge `CURLOPT_SSL_VERIFYPEER` and
`CURLOPT_SSL_VERIFYHOST`.
The name check now uses a function from lib/vtls/openssl.c which will
need attention for when TLS is not done by OpenSSL or is disabled while
QUIC is enabled.
Possibly the servercert() function in openssl.c should be adjusted to be
able to use for both regular TLS and QUIC.
Ref: #8173Closes#8178
QUIC Transport Parameters Extension has been changed between draft-29
and latest RFC9001. Most notably, its identifier has been updated from
0xffa5 to 0x0039. The version is selected through the QUIC TLS library
via the legacy codepoint.
Disable the usage of legacy codepoint in curl to switch to latest
RFC9001. This is required to be able to keep up with latest QUIC
implementations.

Closes#7960
ngtcp2_conn_client_new and nghttp3_conn_client_new are now macros.
Check the wrapped functions instead.
ngtcp2_stream_close callback now takes flags parameter.
Closes#7709
- the data needs to be "line-based" anyway since it's also passed to the
debug callback/application
- it makes infof() work like failf() and consistency is good
- there's an assert that triggers on newlines in the format string
- Also removes a few instances of "..."
- Removes the code that would append "..." to the end of the data *iff*
it was truncated in infof()
Closes#7357
The latest GnuTLS-3.7.2 implements disable switch for TLSv1.3 compatible
mode for middle box but it is enabled by default, which is unnecessary
for QUIC.
