annotate src/event/ngx_event_quic.c @ 8439:cef417a24755 quic

QUIC: cleaned up quic encryption state tracking. The patch removes remnants of the old state tracking mechanism, which did not take into account assimetry of read/write states and was not very useful. The encryption state now is entirely tracked using SSL_quic_read/write_level().
