1e04c91d3c Server window fix clear 
A leftover from when window_t held MonitorElement::Ref
which it no longer does.

c0126d9a1c server: pipeline=true windowing 
Implement flow control windows in the server itself,
so that this applies to all Monitor.

Then the reportRemoteQueueStatus() callback is only needed
to deliver the initial window update.

This is done by not calling Monitor::release() immediately
when pipeline=true.  Rather, hold onto MonitorElement s
until an ack is received.

Also addresses a race with clearing _channelMonitor
vs. having send() queued at/after destroy().

656e2fcfd4 PVA server avoid possible data race 
The operation member variable is set by from the
returned pointer, and within the *Connect callback.
Make sure these down race.

12e7b7864b fix s_channelNameToProvider hack 
Move from global to ServerContext, apply lock, and
properly test if no provider has claimed, eg an attempt
at unadvertised PV (still wouldn't work, but at least
wouldn't crash).

0161799c93 must zero osiSockAddr prior to use! 
RTEMS depends on this or eg. bind()
will fail because comparison with
list of interface addresses is done
with memcmp()!
