    gprs: Add patch mode configuration
    
    Currently the gbproxy tries to patch BSSGP, GMM Attach Request,
    and (unencrypted) GMM Attach Accept if RAI patching is requested.
    
    This patch adds a configuration command to set the level up to which
    the messages shall be modified. If this is not possible, an error
    counter is incremented. Setting the level to 'default' (which is the
    default) enables patching of BSSGP and GMM Attach messages without
    generating errors when it fails due to encryption.

    gprs: Add MCC/MNC patching
    
    This adds a feature to patch the MNC/MCC fields of messages going
    to and coming from the SGSN. To enable this feature, the gbproxy's
    VTY commands 'core-mobile-country-code' and/or
    'core-mobile-network-code' must be used. All packets to the SGSN are
    patched to match the configured values. Packets received from the
    SGSN are patched to the corresponding values as last seen from the BSS
    side.
    
    Note that this will probably not work with a gbproxy used for several
    BSS simultaneously.
    
    Note also, that encrypted packets will not be patched.

    gprs: Separate LLC parsing from LLC state handling
    
    Currently LLC parsing is part of gprs_llc.c which needs large parts
    of the SGSN code parsing to fulfill its link dependencies.
    
    This patch moves the functions that just do plain parsing, dumping,
    and FCS computation to a different file to avoid these dependencies
    if LLC stateful processing is not needed. It also exposes
    struct gprs_llc_hdr_parsed and enum gprs_llc_cmd publically.
