This allows dissector lists to be looked up by name, so they can be
shared by multiple dissectors.
(This means that there's no "udplite" heuristic dissector list, but
there shouldn't be one - protocols can run atop UDP or UDPLite equally
well, and they share a port namespace and uint dissector table, so they
should share a heuristic dissector table as well.)

Rename some routines to indicate that they handle more than just

We don't yet have any libwiretap code that supplies records other than

REC_TYPE_PACKET, or any code to support plugins for handling
REC_TYPE_FILE_TYPE_SPECIFIC records; this is just the first step for bug

This adds the ability for Lua scripts to register heuristic dissectors
for any protocol that has registered a heuristic dissector list, such
as UDP, TCP, and ~50 others. The Lua function can also establish a
conversation tied to its Proto dissector, to avoid having to check the
heuristics for the same flow. The example dissector in the testsuite
has also been enhanced to include a heuristic dissector, to verify
the functionality and provide an example implementation.

The OP asked 9169 to be reopened because the capture was spewing ~40GB of output
when dissected with tshark. Investigation showed this was because the HTTP
dissector was requesting ONE_MORE_PACKET reassembly a lot, and TCP was adding
each step as a data-source which was being printed by tshark's hex dump. This
was leading to O(n^2) of output.
To fix, introduce function remove_last_data_source which removes the most recent
data source from the list. If the subdissector in TCP reassembly asks for
ONE_MORE_PACKET, assume it hasn't added any tree items (since it shouldn't have)
and remove the data source since it is unnecessary.
This may break dissectors which add tree items and *then* return
ONE_MORE_PACKET, since they will have their data source removed out from under
them. I believe those cases should be fixed to not add tree items until they're
sure they have enough data.

This is a VERY PRELIMINARY version of tfshark. It's an attempt to jumpstart FileShark and its architecture. Right now it's mostly just a very stripped down version of tshark with all of the necessary build modifications (including now building filetap library since tfshark depends on it)
This code has helped me identify what I believe to be all of the necessary layers for a complete fileshark architecture. And those layers will slowly be added in time (patches always welcome!).

The main driving force for this was my new Decode As functionality (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9450) that wants a dissector/subdissector table relationship for all dissectors wanting to use Decode As functionality. The ethertype() function provides the value to the "ethertype" subdissector table, so I think it should be matched to a dissector. Only odd side effect is the display filter of "ethertype" returns no packets because there is no "item" associated with the dissector.
