I would like to see this brought back in 5.4, but with a different
implementation. I think that the 'luaL_openlibs' function should have a
noenv argument that would allow users to specify which behavior they
want. And if the only breaking change is picking 0 or 1 to specify to
this function, it seems acceptable to have during a 5.x version bump.
