Universal Messaging client should drop messages which exceed nSession::getMaxBufferSize().

An exception is thrown if a Universal Messaging client sends an input buffer whose size exceeds the server's buffer size (default value 20 MB), where before it would have failed and retried forever.

This is now fixed.
