commit d07ccc09369db365038a8eabf65ae9a54e80abd5
Author: Harald Welte <laforge at>

    gprs_gmm.c: Preform LLME operations only if we have one
    In case the GMM message did not arrive over a Gb interface, there is no
    LLME (and thus the associated pointer is NULL).  Don't try to perform
    operations on a NULL LLME.

    gprs_gmm.c: Make TLLI handling specific to Gb interface
    Soem of the operations we perform in the GMM layer are specific to the
    GPRS/EDGE radio access network and its Gb interface.  Let's make them
    conditional to that in preparation of supporting an Iu interface.

    gprs_gmm.c: Don't try to de-reference NULL mmctx
    There was a comment in the code that certain GMM messages require a
    valid mmctx pointer.  However, nothing actually checked if that pointer
    was in fact non-NULL.  We plainly crashed if a MS would send us the
    wrong message in the wrong state.

    rename gsm0408_gprs_rcvmsg() to gsm0408_gprs_rcvmsg_gb()
    This is the entry point for GMM from Gb.  We will create a new one
    for Iu, so let's be explicit rather than implicit.

    prepare sgsn_mm_ctx for Gb and Iu mode (UMTS)
    Let's explicitly mark those sgsn_mm_ctx members that apply for Gb mode
    and (upcoming) Iu mode, respectively.
