Backwards-compatible enhancement to the asTrapWrite API to provide listener routines with the data being put by the client. The asTrapWriteMessage structure is extended with 3 new fields for data type, element count and a pointer to the source buffer. Tim Mooney requested this enhancement for his caPutRecorder code, which doesn't work if the record overwrites the new value within its process() routine, e.g. when jogging a motor record.
