* more RSL and 04.08 constant defines
* initialize some data structures before using them in RSL
* DATA_REQ is a transparent message
* more elaborate DEBUGP statements here and there
* don't call 04.08 with zero-length RSL DATA INDICATION
* reject 04.08 CC HOLD and RETRIEVE, as we don't support them yet
