erl_nif: add make_atom_len, make_existing_atom_len and make_string_len
Add new NIF API functions - enif_make_atom_len - enif_make_existing_atom_len - enif_make_string_len These are basically the same as enif_make_atom, enif_make_existing_atom and enif_make_string except that the new functions require a length parameter instead of a null-terminated C-string.
