(etc::set_last_modified): Remove obsolete function. * path.cc (etc::change_possible): Revert type to bool. (etc::test_file_change): Do not test for negative values of change_possible and do not set it to -res. (etc::dir_changed): When the handle is NULL, call memset instead of test_file_changed. When the handle is invalid, return true. (etc::file_changed): Remove unneeded check for !fn[n].
