Support TCP zero window probes.
As per RFC 1122 4.2.2.17, when the remote advertizes zero receive window,
the sender needs to probe for the window-size to become non-zero starting
from the next retransmission interval. The TCP connection needs to be kept
open as long as the remote is acknowledging the zero window probes.
We reuse the retransmission timers to support this.
Fixes #1644
