luaL_newstate in Lua 5.4

[actboy168 <actboy168@...>]

To quote from the reference manual :

> luaL_newstate [-0, +0, –]
> Returns the new state, or NULL if there is a memory allocation error.

But now luaL_openlibs will call lua_newuserdatauv and luaL_ref, and then they have a chance to raise a memory error.
