Guy Harris 19a8eafc15 Use luaL_{check,opt}integer() rather than luaL_{check,opt}int().
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():

Michael Mann 6d207fe5f4 Remove private_data member from packet_info structure.
Dissectors should pass data directly to their subdissectors through the data parameter (of new-style dissectors). This avoids unintentional "trampling" from other dissectors trying to "share" private_data member.

Hadriel Kaplan de441241ef Enhance Lua API doc generator and add more API info
This enhances the Lua API doc generator Perl script to handle
meta-information in description comments, such as bold, italics,
raw code, version info, etc.

The supported markup and codes are documented in make-wsluarm.pl.

It's not beautiful Perl code (I don't know Perl), and I'd rather
do it using Lua, but I think keeping it Perl makes more sense in
the long run.

Hadriel Kaplan 04c39bb097 Add Lua heuristic dissector support
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.

Hadriel Kaplan 696353c129 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.

Hadriel Kaplan 9246a709bf Cleanup on aisle 5: normalizes the Lua code to follow common schema/model
Over time the various wslua classes/functions have gotten moldy, with different
ways of doing similar things. Some of it can't be changed without breaking
backwards compatibility for Lua scripts, so I didn't do that. But I did what
I could. The biggest change is a refactoring of how accessors/attributes
are handled in the code, so that most of them work the same way using the
same code.

Specific changes made:
 * Added null/expired checking macro to class declarations for many classes
 * Removed extraneous pointer/expired checking, since checkFoo() does that already
 * Fixed "errors" reported by clang static analyzer; they were false positives, but it was easier to get it to stop complaining by changing the code
 * Moved internal wslua functions from wslua_utils.c into a new 'wslua_internals.c' file
 * Changed Listener/NSTime/Pinfo/Proto to use a common setter/getter accessor/attribute code model, instead of each of them doing their own
 * Fixed some API doc mistakes, mostly around attributes that were documented as read-only but were actually read-write

Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
strtol() and strtoul().

Change some data types to avoid those implicit conversion warnings.

When assigning a constant to a float, make sure the constant isn't a
double, by appending "f" to the constant.

Constify a bunch of variables, parameters, and return values to
eliminate warnings due to strings being given const qualifiers.  Cast
away those warnings in some cases where an API we don't control forces
us to do so.

Enable a bunch of additional warnings by default.  Note why at least
some of the other warnings aren't enabled.

randpkt.c and text2pcap.c are used to build programs, so they don't need
to be in EXTRA_DIST.

If the user specifies --enable-warnings-as-errors, add -Werror *even if
the user specified --enable-extra-gcc-flags; assume they know what
they're doing and are willing to have the compile fail due to the extra
GCC warnings being treated as errors.

Stig Bjørlykke 82e0b65038 Added a private hash table to transport string values between dissectors.
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.
