This pull request introduces three new functions:
quicly_qos_new,quicly_qos_send, andquicly_qos_receive, and adds one callback:quicly_qos_is_writing.When utilizing QUIC on Streams instead of QUIC version 1, applications should use the aforementioned send and receive functions instead of
quicly_sendandquicly_receive. Quicly will continue to guide applications on when to invoke the send function; applications can determine the appropriate timing by callingquicly_get_first_timeout.quicly_get_first_timeoutwill call thequicly_qos_is_writingto see if quicly can write more.
