Luabind adapted to Lua 5.2

Hi,

Lua version 5.2.0 has been released a week ago, and since I am
curious to test it, I adapted the Luabind library to Lua 5.2.

There has been a prior effort by Teto [1] to port Luabind to a Lua
5.2 release candidate, adopted in a git branch by Ryan Pavlik [2].
To keep changes minimal, however, and learn about the differences
between Lua 5.1 and 5.2, I started from scratch following the
Lua 5.2 manual [3].

My adaptation of Luabind to Lua 5.2 is available at:

http://git.colberg.org/luabind.git
https://git.colberg.org/luabind.git
git://git.colberg.org/luabind.git

A tarball snapshot of the repository may be found at:

http://sourceforge.net/projects/halmd/files/libs/luabind/

The Luabind test suite passes both with Lua 5.2 and 5.1.


The repository is based on Luabind upstream commit 3044a90, and
contains minimal changes for compatibility with Lua 5.2, as well
as the cast graph cache bug fix [4].

I invite everyone to give it a try, and merge/cherry-pick into your
personal Luabind branches. As mentioned above, I made sure to keep
the changes minimal. Further, the code is *backwards compatible*
with Lua 5.1. The macros for Lua 5.1 compatibility are written
thus that the corresponding lines may simply be deleted to get
rid of Lua 5.1 compatibility in the far future.

Regards,
Peter
