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).

osmo-sgsn.git fb6cf3221ef4989441c09a650011e4a334c37d12

Changes made:

* Add 'osmo_' prefix to gprs_llc_fcs(),
* osmo_gprs_llc_fcs() takes size_t and returns uint32_t,
* crc24_calc() takes size_t.

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.

Vadim Yanitskiy ed06cbbfbc libosmo-gprs-rlcmac: check-in PDU definitions from osmo-pcu.git 
This commit introduces a new library called 'libosmo-gprs-rlcmac',
which is going to be used by osmo-pcu and osmocom-bb for parsing
and generation of PDUs defined using CSN.1 (see 3GPP TS 24.007).

The actual RLC/MAC definitions are imported from osmo-pcu.git [1].
