Debug cleanup. + all dumps are moved under one of the following macros (undefined by default): NGX_QUIC_DEBUG_PACKETS NGX_QUIC_DEBUG_FRAMES NGX_QUIC_DEBUG_FRAMES_ALLOC NGX_QUIC_DEBUG_CRYPTO + all QUIC debug messages got "quic " prefix + all input frames are reported as "quic frame in FOO_FRAME bar:1 baz:2" + all outgoing frames re reported as "quic frame out foo bar baz" + all stream operations are prefixed with id, like: "quic stream id 0x33 recv" + all transport parameters are prefixed with "quic tp" (hex dump is moved to caller, to avoid using ngx_cycle->log) + packet flags and some other debug messages are updated to include packet type
