faccessat, etc.: support AT_FDCWD-only use * lib/at-func.c: If GNULIB_SUPPORT_ONLY_AT_FDCWD, then support this function only if its first argument is AT_FDCWD. Emacs wants faccessat for AT_EACCESS but not for any first-arg values other than AT_FDCWD, so it doesn't want all the openat machinery with fchdir etc. * modules/faccessat, modules/fchmodat, modules/fchownat (Files): * modules/fstatat, modules/mkdirat, modules/openat (Files): * modules/unlinkat (Files): Remove lib/openat-priv.h, as at-internal supplies this file. Removing this file here allows us to support programs like Emacs that avoid at-internal.
