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.

and have dissectors for protocols that run at the OSI network layer
register themselves with it using "dissector_add()".
Make various dissectors static if they can be, and remove from header
files declarations of those dissectors.
