Vadim Yanitskiy 0b5a816356 llc: make logging category configurable 
Similar to Icfef6de126304da81120f1d7b212992ead3409aa, let's add
osmo_gprs_llc_set_log_cat() allowing the API users to change
logging category for libosmo-gprs-llc (DLGLOBAL is default).

Vadim Yanitskiy 4566897df8 llc: enum osmo_gprs_llc_primitive: drop Req/Ind/Rsp/Cnf 
The libosmocore's prim API offers 'enum osmo_prim_operation', which
contains all required primitive operations: Req/Ind/Rsp/Cnf.  Having
LLC primitive types discriminated by operation is redundant.
