edge: Add unified decoder methods for GPRS/EGPRS

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.
