This is not yet complete. Building should
still work with Lua 5.1.4, but needs
-DLUA_COMPAT_ALL in CPPFLAGS when compiled
against 5.2.0. Automatically handling
this in configure is still a TODO.

Backport from trunk of the following revisions:

r1221205: Make mod_lua compile with lua 5.2.x.
MOdified patch submitted by NormW (nornw gknw net).

r1239029: luaL_reg was already deprecated in Lua 5.1.4.
It is gone in Lua 5.2.0 and was replaced by luaL_Reg
which already existed in 5.1.4. So use that one.

r1239030: Remove luaL_reg macro definition no longer needed
and simplify lua_load compatibility macro.

I haven't backported docs for the cache-invalidate
env var, since although it is present in 2.4.x
the functionality around it was removed for future
definition, so I guess it is not really useful
right now.

Please correct me if tha is wrong and we should
add the cache-invalidate to the 2.4.x docs
like we have right now in trunk.
