    osmo-nitb support for codec negotiation
    
    Since codec negotiation is done automatically, there is no need to define
    codec for TCH/F and TCH/H via VTY anymore.

    If requested TCH/H channel is not available, try assigning TCH/F
    
    If MNCC application requests a half rate channel, the channel might not be
    available, due to different cell configuration, so the full rate channel
    is used.

    Drop bad speech frames rather than forwarding them via RTP
    
    Some RTP endpoints may not check for bad frame indications, so a frame
    that is marked as bad may be still decoded, which creates anoying noise.
    This patch drops these frames. It depends on the SIP endpoint how these
    dropped frames are handled. (insert silence, extrapolate speech...)

    Traffic cannot sent to BTS, if there is (currently) no logical channel
    associated with the transaction.

    Finished support for all codecs (RTP bridge and MNCC interface)
    
    The codes is not yet tested.
    
    AMR rate is currently fixed to 5.9k.

    Fixed delay problems, if RTP stream jitters too much
    
    The RTP stream is generated or forwarded by OpenBSC to nanoBTS. Due to
    switching of streams (hold/retrieve call), packet loss or even stalling
    of sender's process, the time stamp must be corrected. If outdated
    packets are received, they get dropped.

    Allow dynamic RTP payload types between application and MNCC interface
    
    Since EFR/AMR/HR codecs use dynamic RTP payload, the payload type can
    be set. If it is set, the frame type must be set also, so OpenBSC
    knows what frame types are received via RTP.
    
    This modification only affects traffic beween application and MNCC
    interface, not the RTP traffic between OpenBSC and BTS.

    Adding handling of BFI (Bad Frame Indicatior) of received TRAU frames
    
    If a bad TRAU frame is received, it is forwarded to MNCC application
    as GSM_TCHF_BAD_FRAME. The application can now handle the GAP of
    missing audio. (e.g. with extrapolation)
    
    If TRAU frames are forwarded via RTP, bad frames are dropped, but frame
    counter and timestamp of RTP sender state is increased.

    Adding traffic forwarding via RTP to remote application
    
    Instead of forwarding traffic through MNCC interface, traffic can
    now be forwarded to a given RTP destination. A special MNCC message
    is used for that. The traffic can still be forwarded through MNCC
    interface when this special MNCC message is not used.
    
    It also works with E1 based BTSs.
    
    In conjunction with LCR's "rtp-bridge" feature, the RTP traffic
    can be directly exchanged with a remote SIP endpoint, so that the
    traffic is not forwarded by LCR itself. This way the performance
    of handling traffic only depends on OpenBSC and the remote SIP
    endpoint. Also the traffic is exchanged with the SIP endpoint
    without transcoding, to have maximum performance.
