    osmo-nitb support for codec negotiation
    The caller's most preferred codec is selected out of the union of codecs,
    which both parties support.
    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 instead.

    Fix: If paging for half rate was requested, use hr, if supported by MS

    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 forwarded, which creates anoying noise.
    This patch drops these frames. It depends on the other RTP endpoint how
    dropped frames are handled. (insert silence, extrapolate speech...)

    Add check for non existing lchan at tch_frame_down()
    Traffic cannot sent to BTS, if there is (currently) no logical channel
    associated with the transaction.
    This happens, if TCH traffic is received from upper layer, but there is
    no lchan available before completing immediate assignment, handover or
    assignment process.

    Send RADIO LINK TIMEOUT value via OML attribute to BTS
    The same radio link timeout value is used for BTS and MS side.

    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.

    Add traffic forwarding via RTP to remote application
    Instead of forwarding traffic through MNCC interface, traffic can
    be forwarded to a given RTP peer directly. A special MNCC message
    is used to control the peer's destination. 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.
    Increment MNCC version to 5.
