This adds the ability for Lua scripts to register heuristic dissectors
for any protocol that has registered a heuristic dissector list, such
as UDP, TCP, and ~50 others. The Lua function can also establish a
conversation tied to its Proto dissector, to avoid having to check the
heuristics for the same flow. The example dissector in the testsuite
has also been enhanced to include a heuristic dissector, to verify
the functionality and provide an example implementation.

This change adds the ability to pass on to lua scripts loaded from the
command-line (tshark or wireshark) additional arguments supplied by the
command-line. This will help us in our testsuites, but also might be
useful for user-created scripts. The additional arguments are passed in
using the '-X' eXtension switch.

routine to recognize that type of plugin.
In particular applications, only process the relevant plugin types.
Add a Makefile.common to the codecs directory.

This is not a 100% correct implementation at the time because the

a preference in a single Lua plugin is changed.

that directory since 2001 and reading from that directory was only left in for
backwards compatibility with versions prior to r4702. I think it's now safe
to remove that backwards compatibility.
This eliminates the last argument of get_persconffile_path().

epan/show_exception.c, as it's used outside
epan/dissectors/packet-frame.c. Update their callers to include
<epan/show_exception.h> to get their declaration.
Add a CATCH_NONFATAL_ERRORS macro that catches all exceptions that, if
there's more stuff in the packet to dissect after the dissector call
that threw the exception, doesn't mean you shouldn't go ahead and
dissect that stuff. Use it in all those cases, including ones where
BoundsError was inappropriately being caught (you want those passed up
to the top level, so that the packet is reported as having been cut
short in the capture process).
Add a CATCH_BOUNDS_ERRORS macro that catches all exceptions that
correspond to running past the end of the data for a tvbuff; use it
rather than explicitly catching those exceptions individually, and
rather than just catching all exceptions (the only place that
DissectorError should be caught, for example, is at the top level, so
dissector bugs show up in the protocol tree).
Don't catch and then immediately rethrow exceptions without doing
anything else; just let the exceptions go up to the final catcher.
Use show_exception() to report non-fatal errors, rather than doing it
yourself.
If a dissector is called from Lua, catch all non-fatal errors and use
show_exception() to report them rather than catching only
ReportedBoundsError and adding a proto_malformed item.
Don't catch exceptions when constructing a trailer tvbuff in
packet-ieee8023.c - just construct it after the payload has been
dissected, and let whatever exceptions that throws be handled at the top
level.
Avoid some TRY/CATCH/ENDTRY cases by using checks such as
tvb_bytes_exist() before even looking in the tvbuff.

This works between C and Lua.
In C the pinfo.private_table pointer must be initialized using
g_hash_table_new (g_str_hash, g_str_equal);
In Lua the values are available using pinfo.private.<key>, and the
table is created automatically on first usage. It's possible to use
this datatypes: nil, boolean, number and string, but every value
is converted to string so numbers must be converted using tonumber()
on usage. Boolean is either nil or an empty string.

We can have a case where one Lua dissector calls another Lua dissector,
so we can't mark all objects when only one dissector is completed.
