We have no plans about this for the libraries. Libraries are quite
modular and use too many facilities to be parameterized.

About the core, we moved lua_dofile (currently lua_loadfile) to outside
the core, so that it is easier to write your own file I/O routines.

About memory management, all calls are concentrated in a single point,
so it is quite easy to change. Is it really a good idea to go a step
further and implement that through a "callback" function?
