Add test suite for verifying Lua global variables/tables of previous releases have not disappeared.

Several bugs have been introduced due to changing of perl scripts or #define names, such
that things exported into Lua have dissapeared or changed unintentionally. This commit
adds a test suite which compares the Lua global table with the ones from previous
releases (1.8 and 1.10), to verify nothing has gone missing. New items can be added, but
old ones cannot go away. The added script to verify these things, called 'verify_globals.lua',
also has the ability to display what's new - i.e., what was not in the olrder releases.

Lastly, this commit also fixes a bug: MENU_STAT_ENDPOINT became MENU_STAT_ENDPOINT_LIST
due to a change in the make-init-lua.pl perl script in this 1.11 release.

+-- This was changed for Wireshark's use by Hadriel Kaplan.
+--
+-- Changes made:
+-- * provided 'serialize' option to output serialized info (ie, can be marshaled),
+--   though note that serializing functions/metatables/userdata/threads will not
+--   magically make them be their original type when marshaled.
+-- * provided 'notostring' option, which if true will disabled calling __tostring
+--   metamethod of tables.
+-- * made it always print the index number of numbered-array entries, and on separate
+--   lines like the normal key'd entries (much easier to read this way I think)
+-- New public functions:
+-- inspect.compare(first,second[,options])
+-- inspect.marshal(inString[,options])
+-- inspect.makeFilter(arrayTable)
+--
+-- For the *changes*:
+-- Copyright (c) 2014, Hadriel Kaplan
+-- My change to the code is in the Public Domain, or the BSD (3 clause) license if
+-- Public Domain does not apply in your country, or you would prefer a BSD license.

+-- The option 'ignore' is similar to 'filter', except matching ones
+-- are not checked for existence in the tables at all.

+-- Setting the 'depth' option applies as in inspect(), to both tables.
