networking. We will introduce a trans_bts in a second.

it for certain vessels with known problems.

In case transcoding is disabled no error has happened, return
a zero. This is fixing starting the nat without transcoding.

The transcoder RESET is using the same extensions to reset all
endpoints on a remote site. This makes sure that all allocations
can be made in a properly configured network.

mgcp: Forward data from the BTS-in to the transcoder
...
Bind a new port for the transcoder, forward data from the BTS
to the transcoder, and from the transcoder to the network. Leave
BTS-IN where it is, BTS-OUT can now be after the transcoding took
place. We send the data from the BTS RTP port.
This whole route will be guarded by the transcoder_ip and if it is
NULL (current default) it will not go through the transcoder.

mgcp: Add a call tap feature to forward audio to another forward port

For debugging it is useful to forward (tee) UDP packets to another
system and use gstreamer to inspect the rtp stream. This is untested
code and might contain bugs.... and of course only tap your own calls.

mgcp: Attempt to separate the RTP/RTCP port for the Network and for the BTS

mgcp: Attempt to count missing RTP packets with a basic calculation
...
This code compares the UDP sequence numbers of two RTP messages
and guesses if packets are missing. It is guessing in two ways:
1.) by default the sequence number is 0, so on the first
value we ignore the jump... we might ignore a real issue
in case of a wrap around which is easily possible as the
sequence should be a random number.
2.) the UDP stream might have been reordered on the network
and we would see the jump...
In any case these two shortcomings are acceptable for the feature
that is meant to provide some basic analysis..
