gb: Add beginnings of a new BSSGP implementation

Similar to ns2 superseding ns, we now also intoduce a next generation
of BSSGP related code to libosmogb.  However, this is not aiming to
be a full implementation yet, but simply those parts that we currently
need from the revamped osmo-gbproxy.

The gprs_bssgp2.[ch] differs in two ways from the old code:
* it separates message encoding from message transmission
* it supports more recent specs / IEs

bssgp_bvc_fsm.c is a genric implementation of the BSSGP BVC
RESET/BLOCK/UNBLOCK logic with support for both PTP and signaling,
both on the SGSN side and the BSS side.
