Redo the way the variable part of COTP and CLTP packets are handled, by having a single routine to handle it for all packets, rather than having the dissector for each type of packet handle the parameters those packets are supposed to have. Fix "is_LI_NORMAL_AK()" to test (heuristically) whether an AK COTP packet is normal rather than extended, rather than testing whether it's normal, and invert the test where it's used (i.e. make what it does correspond to what its name says, which means we invert the test it does, and then change the code that uses it appropriately). Add support for the "preferred maximum TPDU size" and "inactivity timer" parameters, and fix various problems in the dissection of particular parameters. svn path=/trunk/; revision=2100
