commit dab54b91783d5197e0129de950a705e2da2a4cb9

    trx: Enable EGPRS handling through burst lengths
    
    Existing interfaces are coded with the implicit expectation of using
    a burst sequence length of 148, which is constant with GSM and GPRS.
    That changes with EGPRS, where the burst length may be 444 due to
    the use of 8-PSK instead of GMSK modulation.
    
    Setup the interface to accept and return a length value with the
    burst sequence. This allows 444 length bit vectors to/from the
    EGPRS decoder/encoder. Length is explicitly used as a identifier for
    8-PSK vs. GMSK modulated sequences.

    trx: Add EGPRS coding and decoding procedures
    
    Handles uplink decoding and downlink encoding procedures for MCS 1-9.
    Includes Type 1, 2, and 3 headers and tables from 3GPP TS 44.060 in
    order to independently recover coding and puncturing scheme (CPS)
    parameters for each coded message.
