Fix the logic for sending zero window updates.
Today we have the logic split in two places between endpoint Read() and the
worker goroutine which actually sends a zero window. This change makes it so
that when a zero window ACK is sent we set a flag in the endpoint which can be
read by the endpoint to decide if it should notify the worker to send a
nonZeroWindow update.
The worker now does not do the check again but instead sends an ACK and flips
the flag right away.
Similarly today when SO_RECVBUF is set the SetSockOpt call has logic
to decide if a zero window update is required. Rather than do that we move
the logic to the worker goroutine and it can check the zeroWindow flag
and send an update if required.
