    http2: limit number of control frames in server send queue

    An attacker could cause servers to queue an unlimited number of PING
    ACKs or RST_STREAM frames by soliciting them and not reading them, until
    the program runs out of memory.

    Limit control frames in the queue to a few thousands (matching the limit
    imposed by other vendors) by counting as they enter and exit the scheduler,
    so the protection will work with any WriteScheduler.

    Once the limit is exceeded, close the connection, as we have no way to
    communicate with the peer.
