Fix for bug 1036 I looked at this today and found that in fact the PC stuff is pretty hosed up in the SS7 dissectors. For example, MTP3 *looks* OK here (DPC is 4-5-6): Routing label DPC (4-5-6) (394500) but 394500 == 0x60504 == 6-5-4. Something's not right. I made a common PC dissector function for all the SS7 dissectors so as to concentrate all this code in one place (something I've been wanting to do for a while anyway) and fixed the reported problem as well as the above problem in the attached patch. svn path=/trunk/; revision=19231
