    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.

    trx: Add EGPRS coding support
    
    Add convolutional codes, interleaving, burst mapping, training
    sequences, and necessary header parsing from 3GPP TS 44.060 to
    handle EGPRS MCS codings from 1-9.
