There is a problem with the RANAP dissector in that it
will only dissect packets that have the correct SSN.

However, RANAP, and A-interface (BSSAP/BSAP) protocols
use connection oriented SCCP.  Most of the messages do not
contain an SSN field.

The following messages are used:

UNITDATA
Connection Request
Connection Confirm
Connection Refused
DATA FORM 1
RELEASED
RELEASE COMPLETE

Only the UNITDATA and Connection Request contain an SSN field.

What is the best solution for making sure the dissector gets all
the messages?
