annotate src/event/quic/ngx_event_quic.c @ 9017:c2f5d79cde64 quic

QUIC: separate UDP framework for QUIC. Previously, QUIC used the existing UDP framework, which was created for UDP in Stream. However the way QUIC connections are created and looked up is different from the way UDP connections in Stream are created and looked up. Now these two implementations are decoupled.
