This update added new revisions after undoing existing revisions.  That is
to say, the old revision is not a strict subset of the new revision.  This
situation occurs when you --force push a change and generate a repository
containing something like this:

 * -- * -- B -- O -- O -- O (f7637bc5155e14aabdcae1d3271a43ebbade6ef8)
            \
             N -- N -- N (5724fb76169008c7f7d6bf8ffedbe2a4a78f8e00)

When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.

Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

    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.

    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...)

    Fixed (ipaccess BTS) delay/silence problems, if RTP stream jitters too much
    
    After OpenBSC stalled for some reason (e.g. CPU overload or database
    access) or after speech frames have been lost (MNCC application problems /
    hold/retrieve call), the timestamp and the sequence number of the RTP
    socket state must be corrected. The amount of incrmentation is calculated
    from the elapsed time. Not incrementing timestamp and sequence number would
    cause all frames to be dropped by ipaccess BTS, because the BTS expects
    frames with more recent timestamps.
    
    If speech frames are received too fast, they must be dropped. The timestamp
    and sequence number of the RTP socket state are not changed in this case.
    Incmenetating timestamp and sequence number would causes high delay at
    ipaccess BTS, because the BTS would queue the frames until the timestamp
    matches the current time.
    
    There is a simple test case:
    
    Make a call between two phones and check the delay. (When using LCR, make
    a call to the echo test.) The press CTRL+z to suspend OpenBSC process for
    a few seconds and enter "fg" to continue OpenBSC process. There shall be no
    change in the delay, even after repeating this test many times.

    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.
