Lua prior to 5.3 defined luaL_{check,opt}int() as macros wrapping
luaL_{check,opt}integer() with a cast to int; Lua 5.3 doesn't.
It sounds as if the Lua developers are deprecating luaL_{check,opt}int():

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.
