1) pvaClientChannel no longer issues an error message on disconnect.
This should never have been done.
When pvaClient is used within a database, it caused error mesaage when database exits.
2) pvaClientGet,Monitor,Process,Put,PutGet now let pvaClientChannel handle getRequesterName and message.
This leads to better error messages.
1) Fix issues #66 and #70
2) All tests in exampleCPP/testMultiplePutGet now work successfully.
I still want to do more testing, especially on connection management.
Also relese notes and documentation needs work.
1) Added method PvaClientNTMultiData::getChannelChangeFlags.
2) In pvaClientMultiChannel made methods not intended for client protected.
3) Fixed many connection related problems.
4) Cleaned up doxygen.
