fts, getcwd, glob: audit for dirfd returning -1 * lib/fts.c (opendir): Remove #define; no longer used. (opendirat): New arg PDIR_FD. All callers changed. (fts_build, _opendir2): Use new opendirat to avoid the need for dirfd, or for checking whether dirfd returns a negative value. Don't use opendir; always use openat followed by fdopendir. * lib/getcwd.c (__getcwd): Don't reset fd; fdopendir no longer clobbers it. * lib/glob.c (link_exists_p): Add comment explaining why dirfd never returns -1 here. * modules/fts (Depends-on): Remove dirfd. * modules/getcwd (Depends-on): Likewise.
