0084b6e60a de-virt Transport::getRevision() 
Makes clear that this is/was only for TCP,
and eliminate redundant storage.  Also apply
locking to this storage.

Use header version directly in search handler.
Correct as only UDP search is actually used atm.

fa484a883a redo security (aka. access control) 
Break up monolithic SecurityPlugin API into three parts.

1. Authentication.
2. Authorization.
3. Access Control decision.  Left to ChannelProviders

a1a2e71ecc fix ServerCancelRequestHandler::handleResponse 
Thus far this has been dead code as ServerChannel::getRequest()
returned a Destroyable which was actually a BaseChannelRequester
sub-class, not a ChannelRequest sub-class.

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

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()!
