Osmocom Packet control Unit (PCU): Network-side GPRS (RLC/MAC); BTS- or BSC-colocated

This commit adds new RLC block decoder functions that support both GPRS and EGPRS. The code path is selected based on the value of the GprsCodingScheme cs object. - rlc_parse_ul_data_header parses the header of an RLC data block including the E and FBI/TI flags (currently supported CS-1 - CS-4, MCS-1 - MCS-4). - rlc_copy_to_aligned_buffer copies an RLC data unit to a byte aligned buffer and returns the unit's length. - rlc_get_data_aligned is a convenience wrapper around rlc_copy_to_aligned_buffer that avoids copying if the data unit is already byte aligned.

This is an implementation of Packet Control Unit (PCU) according to TS 04.60 The PCU is part of BSS, so it connects directly to SGSN. == Current limitations == * No PFC support * No fixed allocation support * No extended dynamic allocation support * No unacknowledged mode operation * No PCCCH/PBCCH support * Only single slot assignment on uplink direction * No half-duplex class support (only semi-duplex) * No handover support * No measurement support * No TA loop * No power loop * No CS loop * No EGPRS
