xdiff: remove unused functions
The functions xdl_cha_first(), xdl_cha_next() and xdl_atol() are not used by us. While removing them increases the difference to the upstream version of libxdiff, it only adds a bit to the more than 600 differing lines in xutils.c (mmfile_t management was simplified significantly when the library was imported initially). Besides, if upstream modifies these functions in the future, we won't need to think about importing those changes, so in that sense it makes tracking modifications easier.
