Add a dissector table indexed by the file type, and, for the

pseudo-header processing, as the pseudo-header has a file-type-specific
record subtype in it, and call the dissector for that file type's

Add a "record type" field to "struct wtap_pkthdr"; currently, it can be
REC_TYPE_PACKET, for a record containing a packet, or
REC_TYPE_FILE_TYPE_SPECIFIC, for records containing file-type-specific
data.
Modify code that reads packets to be able to handle non-packet records,
even if that just means ignoring them.
Rename some routines to indicate that they handle more than just
packets.
We don't yet have any libwiretap code that supplies records other than
REC_TYPE_PACKET or that supporting writing 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.
