annotate src/event/ngx_event_quic.c @ 8314:de8981bf2dd5 quic

Advertizing MAX_STREAMS (0x12) credit in advance. This makes sending large number of bidirectional stream work within ngtcp2, which doesn't bother sending optional STREAMS_BLOCKED when exhausted. This also introduces tracking currently opened and maximum allowed streams.
