    ms: Support new and old TLLIs (TODO)
     - commit message
     - optionally split into MS/storage changes and TBF/BTS usage
     - fully remove per TBF TLLI stuff (other commit?)
     - works with a single E71
     - works slowly with a single Iphone (background updates in progress)
     - both at the same time doesn't work
     -> check again when the iphone has done it's update
     -> check prior commits with both phones

    tbf/test: Optionally show talloc report
    To show the talloc report more easily, this commit adds a call to
    talloc_report_full if the TALLOC_REPORT_FULL environment variable is
    set (the value is ignored). Since the stderr output is checked by the
    test suite, this feature is not enabled by default.

    tbf: Add MS object management to TBF code
    This commit adds MS object creation and cleanup to the TBF related
    code. MS objects are created when a TBF that has been "anonymous" so
    far gets associated with a TLLI. When a TBF is replaced by another,
    the old TBF is detached and the new one is attached to the MS. When
    all TBFs have been detached, the MS object gets deleted.
    The TBF related code should not call attach_tbf/detach_tbf directly
    but use set_ms instead to make sure, that the references are updated
    properly. GprsMs::detach_tbf also calls set_ms(NULL) on the detached
    TBF object.
    The MS object is not really used yet.

    ms: Add GprsMs class to hold per-MS information
    Currently only TBF objects are used to handle the data flow between
    the MS and the SGSN. MS specific data (e.g. pending LLC frames, TLLI)
    is copied between successive TBFs. If all TBFs (uplink and downlink)
    are idle for some time, all information about the MS is discarded in
    the PCU. This makes the implementation of some features more
    difficult, e.g. proper TLLI and timing advance handling,
    connection based CS selection, and proper management of multiple TBF.
    This commit adds the GprsMs class that is intended to hold
    information directly related to the MS and to keep references to the
    active TBFs.
    The class is not yet integrated with the other PCU code. A GprsMs
    object container and MS specific fields (TA, CS) will be added in
    later commits.
    Note that calling detach_tbf() can possibly delete the MS object
    depending on the callback implementation.
