RE: Status PV Gateway fixes/changes from Jeff Hill

["Jeff Hill" <johill@lanl.gov>]

All,

I committed a fix to the gateway today for the following issues:

o Fixed issue where put callback response from IOC with failure status does
not result in put notify response being sent to gw's client 
o Fixed problems with writes not being processed when the gateway runs in
-no_cache mode and a stale variable in the gateway is reactivated
o Improved my patch to the gateway allowing it to determine if a write is
from a ca_put or ca_put_callback, and to accordingly dispatch the
appropriate form of ca_put to the IOC.

There are still some regression test failures, but much further down now.
The failure in caching mode is probably benign, and reflecting what is
expected from a caching mode gateway. These tests pass w/o issue against the
PCAS example server.

At the moment I have to return to some other tasks here but will need to
look further into the -no_cache problem when there is time later this fall.

Running the gateway in -no_cache mode:
