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.

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

Lua-created tvbuffs should be kept around for the duration of pinfo's
lifetime, instead of only for the duration of frame dissection. So
instead of using the frame dissector's frame_end_routine, we'll register
a callback to wmem for pinfo pool's allocator.

Have dfilter_compile() take an additional gchar ** argument, pointing to
a gchar * item that, on error, gets set to point to a g_malloc()ed error
string. That removes one bit of global state from the display filter
parser, and doesn't impose a fixed limit on the error message strings.
Have fvalue_from_string() and fvalue_from_unparsed() take a gchar **
argument, pointer to a gchar * item, rather than an error-reporting
function, and set the gchar * item to point to a g_malloc()ed error
string on an error.
Allow either gchar ** argument to be null; if the argument is null, no
error message is allocated or provided.

Because call_heur_dissector_direct() didn't set the pinfo->heur_list_name
before calling the heuristic dissector, heur_dissect_lua() would invoke
report_failure(). Unfortunately, calling report_failure() within a dissector
can cause problems because GTK continues invoking timed callbacks while
it displays the modal dialog created by report_failure()... without yet
returning from report_failure(). In such a case, it's possible for
epan_dissect_run() to be called while still within the execution of a
previous call to epan_dissect_run(), which casues an assert since
epan_dissect_run() is not reentrant.
So this commit both fixes the call_heur_dissector_direct() bug as well
as avoids using report_failure() within heur_dissect_lua(). It also
upadtes the dissector.lua script used in the testsuite to match the one
pubshied on the wiki, since that script's heuristic dissector triggered
the bug.
