Stefan Eissing 0535f6ec71 http3: initial support for OpenSSL 3.2 QUIC stack ... - HTTP/3 for curl using OpenSSL's own QUIC stack together with nghttp3 - configure with `--with-openssl-quic` to enable curl to build this. This requires the nghttp3 library - implementation with the following restrictions: * macOS has to use an unconnected UDP socket due to an issue in OpenSSL's datagram implementation See https://github.com/openssl/openssl/issues/23251 This makes connections to non-reponsive servers hang. * GET requests will send the indicator that they have no body in a separate QUIC packet. This may result in processing delays or Transfer-Encodings on proxied requests * uploads that encounter blocks will use 100% cpu as detection of these flow control issue is not working (we have not figured out to pry that from OpenSSL). Closes #12734		2024-01-22 16:15:45 +01:00
