Michael Davidsaver 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.

Michael Davidsaver 855335f3b1 client.h guard concurrent callbacks on cancel 
cancel() blocks until concurrent callbacks have
completed.  Also serializes any callbacks for each
Operation/Monitor.

Michael Davidsaver 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.

Michael Davidsaver 1f5c0eedcb MonitorFIFO: open() handle compute() error internally

pvRequest mapping.

Michael Davidsaver 8644f4230d client: simplify monitor type handling 
I think the original logic is correct, but I'm not sure.
Cleverness to avoiding storing a Structure pointer is a
premature optimization anyway.

Michael Davidsaver c93f7a35f7 pva/client.h: no lastRequest() 
until #97 is resolved.  Avoids annoying message.

Michael Davidsaver 135f66393d pva/client.h: Get expose valid bitset 
turns out this is useful after all.

Michael Davidsaver 80db41f1c4 pva/client.h Allow callbacks to unref Operations 
Keep a local (internal) shared_ptr whenever
user callbacks are run.  This allows user
callbacks to drop (reset()/dtor) Operations
or Monitors safely.

Ref must to captured before mutex is locked,
which is safe as the internal weak_ptr is
not changed after build() (despite being non-const)

Michael Davidsaver b5bf6a4ccd client: (shallow) copy into Monitor::root 
Avoid exposing refs. from monitor queue
which might then be used after release().
Also allows users the possibility of caching
getSubField() until root.get() actually changes.
