165313d8f5 client.h add some exception guards 
These are one shot operations anyway,
and allowing user exceptions to propagate
to core PVA isn't helpful.

605c172d3c fix SharedPV allow rpc() while close()'d 
Don't call channelRPCConnect() again during open().

Turns out that a second channelRPCConnect() has
the effect of sending a reply with OK and NULL.

4e5aef3e42 SharedPV allow rpc() while close()'d 
No reason to prevent this as RPCs need not use
the same type (Structure) as get/put/monitor.

f7f4822c08 pva/client.h separate Get and Put 
Apparently some servers (pvDatabase) have different
behavior for ChannelGet::get() and ChannelPut::get() .

ClientChannel::get() now uses ChannelGet::get()
while ClientChannel::put() will automatically
do a ChannelPut::get() and pass the result to
the putBuilder callback.
