QUIC: refactored long header parsing. The largely duplicate type-specific functions ngx_quic_parse_initial_header(), ngx_quic_parse_handshake_header(), and a missing one for 0-RTT, were merged. The new order of functions listed in ngx_event_quic_transport.c reflects this. |_ ngx_quic_parse_long_header - version-invariant long header fields \_ ngx_quic_supported_version - a helper to decide we can go further \_ ngx_quic_parse_long_header_v1 - QUICv1-specific long header fields 0-RTT packets previously appeared as Handshake are now logged as appropriate: *1 quic packet rx long flags:db version:ff00001d *1 quic packet rx early len:870 Logging SCID/DCID is no longer duplicated as were seen with Initial packets.
