fdopendir: fix GNU/Hurd bug
fdopendir(open("file",O_RDONLY)) mistakenly succeeded, with
subsequent readdir() failing with ENOTDIR.
* m4/fdopendir.m4 (gl_FUNC_FDOPENDIR): Check for Hurd bug in
allowing non-directory fds.
* lib/fdopendir.c (rpl_fdopendir): Work around it.
* m4/dirent_h.m4 (gl_DIRENT_H_DEFAULTS): New witness.
* modules/dirent (Makefile.am): Substitute it.
* lib/dirent.in.h (fdopendir): Declare replacement.
* doc/posix-functions/fdopendir.texi (fdopendir): Document this.
* tests/test-fdopendir.c (main): Test something other than
/dev/null, since on Hurd that behaves like a directory.
