Allow either old-style (pre-tvbuff) or new-style (tvbuffified)
dissectors to be registered as dissectors for particular ports,
registered as heuristic dissectors, and registered as dissectors for
conversations, and have routines to be used both by old-style and
new-style dissectors to call registered dissectors.
Have the code that calls those dissectors translate the arguments as
necessary. (For conversation dissectors, replace
"find_conversation_dissector()", which just returns a pointer to the
dissector, with "old_try_conversation_dissector()" and
"try_conversation_dissector()", which actually call the dissector, so
that there's a single place at which we can do that translation. Also
make "dissector_lookup()" static and, instead of calling it and, if it
returns a non-null pointer, calling that dissector, just use
"old_dissector_try_port()" or "dissector_try_port()", for the same
reason.)
This allows some dissectors that took old-style arguments and
immediately translated them to new-style arguments to just take
new-style arguments; make them do so. It also allows some new-style
dissectors not to have to translate arguments before calling routines to
look up and call dissectors; make them not do so.
Get rid of checks for too-short frames in new-style dissectors - the
tvbuff code does those checks for you.
Give the routines to register old-style dissectors, and to call
dissectors from old-style dissectors, names beginning with "old_", with
the routines for new-style dissectors not having the "old_". Update the
dissectors that use those routines appropriately.
Rename "dissect_data()" to "old_dissect_data()", and
"dissect_data_tvb()" to "dissect_data()".
