rtsp: Add error_full callback to GstRTSPWatchFuncs.

Browse source 
The error_full callback is similar to the error callback, but allows for
better error handling. For read errors a partial message is provided to
help an RTSP server generate a more correct error response, and for write
errors the write queue id of the failed message is returned.
