[asterisk-ss7] MATTF libss7

[Attila Domjan]

So, some other stuff are still not implemented.
I worked for extend mtp3/isup for passing required tests here.
Developing mtp2 is quite difficult without analizer. The the moder cpu-s
are fast enough, may help move many part on kernel level, or increase
kernel HZ...
