A non-heuristic dissector, and a call to "conv_dissector_add()" passing
it a pointer to the non-heuristic dissector.

Heuristic dissectors don't show up in the "Decode As" list; protocols in
that list have to have dissectors that return "void", not "gboolean".

If you want it to show up in the "Decode As" list, write a non-heuristic
dissector, have the heuristic dissector call it if the packet passes the
test, and register the non-heuristic dissector in the "tcp" or "udp"
conversation-dissector list with "conv_dissector_add()".
