Clifford Jansen resolved PROTON-2203.
-------------------------------------
Resolution: Fixed
Added a test to prevent duplicate listener socket rearming when fds run out.
The old rearming logic was per kernel socket. Now it is per logical listener
with multiple sockets and backlog draining. The old locking logic with the
context mutex and the rearm_mutex conflated the two. In the new model, there is
reduced contention for the context mutex as everything is now serialized via
the poller/scheduler. Discarding the rearm_mutex should have negligible
performance impact and simplify the code (and make Coverity happier).
