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

---------------------------------------------------------------------- 
uploaded new version of the pcap tool (dahdi_pcap2.c) this version, this
version only logs messages if they are different from the previous one. 
This prevents the pcap from being flooded with FISSU messages and make the
pcaps much more readable.
