John Thacker db8e63614e BT-uTP: Hand to bittorrent dissector, dissect multiple PDUs
Handle uTP payload to the bittorrent dissector.
Implement dissect PDUs to handle more than one bittorrent PDU
in a uTP payload.
Implement basic multisegment PDU tracking; not enough to actually
desegment, but enough to provide a hint to the start offset of the
next PDU when a PDU does span segments. (Provided that they're in
order, but OOO handling isn't implemented yet either.)
Improves #8792.

All cases of the "original" format_text have been handled to add the

Michael Mann d802b5b0ec Add format_text_wmem.
This allows for a wmem_allocator for users of format_text who want
it (dissectors for wmem_packet_scope()).  This lessens the role of
current format_text functionality in hopes that it will eventually
be replaced.

Michael Mann f4b0abc729 Dissectors don't need a journey of self discovery.
They already know who they are when they register themselves.  Saving the
handle then to avoid finding it later.
Not sure if this will increase unnecessary register_dissector functions
(instead of using create_dissector_handle in proto_reg_handoff function)
when other dissectors copy/paste, but it should make startup time
a few microseconds better.

Michael Mann 268841f3e0 Combine Decode As and port preferences for tcp.port dissector table.
This patch introduces new APIs to allow dissectors to have a preference for
a (TCP) port, but the underlying data is actually part of Decode As functionality.
For now the APIs are intentionally separate from the regular APIs that register a
dissector within a dissector table.  It may be possible to eventually combine the
two so that all dissectors that register with a dissector table have an opportunity
to "automatically" have a preference to adjust the "table value" through the
preferences dialog.

The tcp.port dissector table was used as the guinea pig.  This will eventually be
expanded to other dissector tables as well (most notably UDP ports).  Some
dissectors that "shared" a TCP/UDP port preference were also converted. It also
removed the need for some preference callback functions (mostly when the callback
function was the proto_reg_handoff function) so there is cleanup around that.

Dissectors that has a port preference whose default was 0 were switched to using
the dissector_add_for_decode_as_with_preference API rather than dissector_add_uint_with_preference

Also added comments for TCP ports used that aren't IANA registered.

Michael Mann 9bcac48403 Manually add protocol dependencies derived from find_dissector.
Started by grepping call_dissector_with_data, call_dissector_only and call_dissector and traced the handles passed into them to a find_dissector within the dissector.  Then replaced find_dissector with find_dissector_add_dependency and added the protocol id from the dissector.
"data" dissector was not considered to be a dependency.

Michael Mann 21e5a950ad Remove all preferences related to enabling/disabling heuristic dissectors.
The preferences are still supported for backwards compatibility, but the heuristic_protos file has final say on the "preference" to enable/disable a heuristic dissector.

Also add parameter to heur_dissector_add() for the "default" enable/disable of a heuristic dissector. With this parameter, a few more (presumably weak) heuristic dissectors have been "registered" but of course default to being disabled.

Michael Mann 8081cf1d90 Add data parameter to tcp_dissect_pdus() as well as convert it to using "new" style dissectors.
Now that "bytes consumed" can be determined, should tcp_dissect_pdus() take advantage of that?

Should tcp_dissect_pdus return length (bytes consumed)?  There are many dissectors that just call tcp_dissect_pdus() then return tvb_length(tvb).  Seems like that could all be rolled into one.

Evan Huus 37600a157b Rename value string (and similar) functions to use a consistent pattern. This
was done using textual search+replace, not anything syntax-aware, so presumably
it got most comments as well (except where there were typos).

Use a consistent coding style, and make proper use of the WS_DLL_* defines.

Group the functions appropriately in the header.

I ended up getting rid of most of the explanatory comments since many of them
duplicated what was in the value_string.c file (and were out of sync with the
recent updates I made to those in r48633). Presumably most of the comments
should be in the .h file not the .c file, but there's enough churn ahead that
it's not worth fixing yet.
