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
Print the boolean value as its string representation instead of with
%hhu which isn't a format we typically use.

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
A stream reset now causes a CURLE_PARTIAL_FILE error. I'm not convinced
this is the right action nor the right error code.

This could otherwise easily leave libcurl "hanging" after the entire
transfer is done but without noticing the end-of-transfer signal.

quiche has just switched it's qlog serialization format to JSON-SEQ by
default . The spec says this SHOULD use `.sqlog` extension.
I believe ngtcp2 also supports JSON-SEQ by default as of
9baf06fc3f
Let's update curl so that tools know what format we are using!
Closes#8316
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.

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.
