Don't wire into the reassembly code the notion that reassemblies should
be done on flows from one address to another; reassembly for protocols
running atop TCP should be done on flows from one TCP endpoint to
another.
We do this by:
adding "reassembly table" as a data structure;
associating hash tables for both in-progress reassemblies and
completed reassemblies with that data structure (currently, not
all reassemblies use the latter; they might keep completed
reassemblies in the first table);
having functions to create and destroy keys in that table;
offering standard routines for doing address-based and
address-and-port-based flow processing, so that dissectors not
needing their own specialized flow processing can just use them.
This fixes some mis-reassemblies of NIS YPSERV YPALL responses (where
the second YPALL response is processed as if it were a continuation of
a previous response between different endpoints, even though said
response is already reassembled), and also allows the DCE RPC-specific
stuff to be moved out of epan/reassembly.c into the DCE RPC dissector.
