Add compatibility support for both lua-5.1 and lua-5.2,
assuming that the LUA_COMPAT might have been disabled.

- Track posix.fork() and only allow exit() and exec() if the script
has forked. There are other questionable items in posix extensions
too but these are the worst offenders.
- Using Lua registry for tracking forked status might be more Lua-way
option but this'll do for now.
- only the lua posix extension "uses" this by providing putenv()
to Lua, make it conditional and return error if not supported by
the underlying operating system
- don't build internal copy of Lua
- move 3rd party extensions (posix and rexlib) to toplevel luaext/
directory, built by default (unless --without-lua specified)
- auto*foo checks for external Lua
- minimal tweaks to lposix.c and rpmlua.c to get them build with Lua 5.1
