The preference has already been deregistered at that point, so the value
of the preference has been freed and the pointer to it has been set to
null, so it's already been freed and its pointer no longer points to it
and the free from Lua will do nothing.

Capture dissectors could be architected like dissection dissectors, with tables and subtables and possibly using tvbs to pass there data instead of raw byte arrays. This is a first step towards that by refactoring capture_info_packet() to work off of a "capture dissector table"
Registering the capture dissection functions instead of calling them directly also clears up a bunch of dissector header files who sole purpose was providing the capture dissection function definition.

Check if description (protocol name) and short_name are used before
registering the protocol. This because proto_register_protocol() makes
sure there's not already a protocol with any of the names registered
and duplicates will be reported with a g_error() which terminates the
Wireshark unexpectedly.
Also check if short_name contains valid characters.
Give appropriate error messages.

It doesn't actually *close* any handle, so it's best called a "finish"

In libwiretap modules, don't bother setting the finish routine pointer
to null - it's already initialized to null (it's probably best not to
require modules to set it).

The target here is the Decode As dialog where protocols have multiple registrations into a dissector table and that shows up as multiple entries in the Decode As dialog list with the same name so users are unsure which "dissector" they are choosing.
The "default" behavior (done in this commit) is to not allow duplicates for a dissector table, whether its part of Decode As or not. It's just ENFORCED for Decode As.

Move the definitions of hashipv4_t and hashipv6_t to wiretap/wtap.h, as
that's the main place they're used. Change them a bit not to depend on
other stuff from libwireshark, and change the code as required by those
changes.
This should fix the Solaris build; apparently, the Sun^WOracle compiler
is generating code for static inline functions even if they're never
called, so that libwiretap ends up including code that calls tvbuff and
wmem functions.
There's probably further cleanup that could be done here, but this
should at least fix the build, as well as getting rid of a dependency
between two libraries that are at least somewhat independent (libwiretap
should *not* depend on libwireshark, as some programs use libwiretap but
not libwireshark, and, ultimately, we probably want it to be possible to
use libwireshark without libwiretap but that'd be more work).

The dissect_tcp_pdus function in LUA is passed two LUA functions that
get the PDU length and the dissect a PDU. When one of these functions
fail, a longjmp is made to the the caller of lua_pcall.
This is no problem for the PDU length function, but the PDU dissect
function is wrapped in a TRY/CATCH/ENDTRY block which also uses longjmp
and need to be fully executed. Without doing so, LUA exceptions will
crash on a weird location (except_pop).
Fix the crash by not using luaL_error, but throw dissector errors which
properly breaks out of the tcp_dissect_pdus C function and then convert
it to a LUA error such that the dissector can handle it.
Test with `tshark -X lua_script:crash.lua -r ssl.pcap`:
trivial_proto = Proto("trivial", "Trivial Protocol")
function dissect_foo(tvb, pinfo, tree)
error("triggering a LUA error");
end
function get_pdu_len(tvb, pinfo, tree) return 5; end
function trivial_proto.dissector(tvb, pinfo, tree)
dissect_tcp_pdus(tvb, tree, 5, get_pdu_len, dissect_foo)
end
tcp_table = DissectorTable.get("tcp.port")
tcp_table:add(443, trivial_proto)
It should not crash and will print this:
Lua Error: dissect_tcp_pdus dissect_func: [string "crash.lua"]:3: triggering a LUA error

differently than the GTK+ UI. Try to make the logic as plain as possible
since we'll likely have to update it in the future.
The addition of a custom BSSID address types means that we can't assume
