statat: new module, split out from fstatat GNU Emacs needs the POSIX-specified fstatat, but not the gnulib-specified statat and lstat. Split the latter two into a new module 'statat'. * lib/openat.h: Depend on GNULIB_STATAT, not GNULIB_FSTATAT. * lib/openat.h, lib/statat.c (STATAT_INLINE): Rename from FSTATAT_INLINE. All uses changed. * modules/fstatat (Files): Remove lib/statat.c. (gl_MODULE_INDICATOR([fstatat])): Remove. (lib_SOURCES): Remove. (Maintainer): Add self. * modules/statat, modules/statat-tests, tests/test-statat.c: New files. * tests/test-fstatat.c (BASE): Don't define if already defined. (do_stat, do_lstat) [!TEST_STATAT]: Test fstatat instead.
