Add outgoing_colp misdn.conf port parameter.

Select what to do with outgoing COLP information on this port.
0 - Send out COLP information unaltered. (default)
1 - Force COLP to restricted on all outgoing COLP information.
2 - Do not send COLP information.
outgoing_colp=0

Also fixed sending the EctInform message so it always has the
required redirectionNumber parameter when the status is active.
