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.

2016-10-08Combine Decode As and port preferences for tcp.port dissector table.Michael Mann1-24/+10
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.

It ends up dragging in libwireshark headers, which programs not linking with libwireshark shouldn't do. In particular, including <epan/address.h> causes some functions that refer to libwireshark functions to be defined if the compiler doesn't handle "static inline" the way GCC does, and you end up requiring libwireshark even though you shouldn't require it. Move plurality() to wsutil/str_util.h, so that non-libwireshark code can get it without include epan/packet.h. Fix includes as necessary.

Change some data types to avoid those implicit conversion warnings. When assigning a constant to a float, make sure the constant isn't a double, by appending "f" to the constant. Constify a bunch of variables, parameters, and return values to eliminate warnings due to strings being given const qualifiers. Cast away those warnings in some cases where an API we don't control forces us to do so. Enable a bunch of additional warnings by default. Note why at least some of the other warnings aren't enabled. randpkt.c and text2pcap.c are used to build programs, so they don't need to be in EXTRA_DIST.
