BSSGP: Add functions required for true BSS-side BSSGP implementation

The BSS-side of BSSGP requires quite a number of additional functions
for sending unidirectional messages that a SGSN never sends.

This is a first step into completing the BSSGP implementation and making
it ready to be used from osmo-bts and other BTS-side GPRS
implementations.
