The macro lua_newpointerbox does the same job of the lod lua_newuserdatabox
(although in a different way). It creates a "full" userdata and stores
your pointer inside it.

Notice that you do not "create" light userdata, as you do not create
numbers. You can push a light userdata with `lua_pushudataval' (bad name?
maybe we could change it to `lua_pushlightudata'...)
