c4fe7150c9 caChannel: no need for weak pvRequest 
Operations should keep their pvRequest alive.
The only danger of ref. loops with pvRequest
is via PVUnion, which is outside the scope
of pvAccessCPP.

a10534d74d eliminate Connector interface 
no code generically creates UDP or TCP connections,
so this abstraction results only in unnecessary
virtual calls and casts.

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()!

1d56ee7283 pva client ignore CMD_DESTROY_REQUEST reply. 
Presently CMD_DESTROY_REQUEST and CMD_CANCEL_REQUEST aren't acknowledged.
This allows ambiguity in when the request ioid goes out of scope.

Currently, the client forgets about an ioid as soon as the destroy request is sent.
So any in-flight response will be erroneously flagged as "Undecipherable message".

Similarly, a cancel request can cross paths with a reply.
This creates confusion in the event the client starts a new
request immediately after canceling the first.

Let's build some forward compatibility by ignoring replies to
cancel and destroy requests.
