Summary:                    [patch] adding ss7 pcap support to dahdi
Description: 
as per the thread on the libss7 mailing list

1. changes to the dahdi driver to add ioctls to mirror reads/writes
from a signaling channel to a pseudo channel
2. a corresponding user app to set up the mirroring and record the
traffic in a pcap

This seems to work though I'm not sure if it's the best solution
design-wise.
I might be abusing the pseudo channel concept.

to compile the app do the following
gcc dahdi_pcap.c -o dahdi_pcap -lpcap

and the syntax to run it is
./dahdi_pcap chan1  [chan2]* pcap.pcap

e.g.
./dahdi_pcap 16 47 test.pcap

tsearle: We have future plans for revamping the conferencing logic in
DAHDI. I think that if we add this patch as-is it would complicate future
cleanups. So, I think it would be best to merge in the code as experimental
and behind a build flag. sruffell and I have reworked the patch a bit and
re-attached it to the issue for review as dahdi_mirror.patch
