  fdopendir: Fix fd leak and test failure on native Windows.
  
  * lib/dirent-private.h: On mingw, define 'struct gl_directory' as a
  wrapper around the original DIR. On MSVC, add an 'fd_to_close' field to
  'struct gl_directory'.
  * lib/dirent.in.h (DIR): Define when DIR_HAS_FD_MEMBER is 0, i.e. on
  both mingw and MSVC.
  (GNULIB_defined_DIR): New macro.
  (opendir): Avoid incompatible redeclaration.
  (readdir): Consider REPLACE_READDIR.
  (rewinddir): Consider REPLACE_REWINDDIR.
  * m4/dirent_h.m4 (gl_DIRENT_DIR): New macro.
  (gl_DIRENT_H): Invoke it.
  (gl_DIRENT_H_DEFAULTS): Initialize REPLACE_READDIR, REPLACE_REWINDDIR.
  * modules/dirent (Makefile.am): Substitute DIR_HAS_FD_MEMBER,
  REPLACE_READDIR, REPLACE_REWINDDIR.
  --
  * lib/dirfd.c (dirfd): If GNULIB_defined_DIR, just use the
  'fd_to_close' field.
  * m4/dirfd.m4 (gl_FUNC_DIRFD): Set HAVE_DIRFD. Don't set REPLACE_DIRFD
  to 1 if HAVE_DIRFD is 0. If DIR_HAS_FD_MEMBER is 0, ensure dirfd.c gets
  compiled.
  * modules/dirfd (Files): Add lib/dirent-private.h.
  (Depends-on, configure.ac): Simplify conditions.
  --
  * lib/closedir.c: Include <stdlib.h> always, for free().
  (closedir): If GNULIB_defined_DIR, arrange to call close(dirfd(dirp)) at
  the end. On mingw, call free() of dirp. Prefer testing HAVE_DIRENT_H,
  for consistency with dirent.h.
  * m4/closedir.m4 (gl_FUNC_CLOSEDIR): Don't set REPLACE_CLOSEDIR to 1 if
  HAVE_CLOSEDIR is 0. If DIR_HAS_FD_MEMBER is 0, ensure closedir.c gets
  compiled.
  --
  * lib/opendir.c: Include <stdlib.h> always. Include <string.h>.
  (opendir): On mingw, allocate the 'struct gl_directory' through malloc.
  If GNULIB_defined_DIR, set the 'fd_to_close' field to -1. Prefer
  testing HAVE_DIRENT_H, for consistency with dirent.h.
  * m4/opendir.m4 (gl_FUNC_OPENDIR): Don't set REPLACE_OPENDIR to 1 if
  HAVE_OPENDIR is 0. If DIR_HAS_FD_MEMBER is 0, ensure opendir.c gets
  compiled.
  --
  * lib/fdopendir.c (fdopendir): If GNULIB_defined_DIR, use a simple
  implementation based on opendir and the fchdir module. If __KLIBC__,
  don't define unused auxiliary functions.
  * modules/fdopendir (Files): Add lib/dirent-private.h.
  --
  * lib/readdir.c (readdir): On mingw, redirect to the original readdir
  function. Prefer testing HAVE_DIRENT_H, for consistency with dirent.h.
  * m4/readdir.m4 (gl_FUNC_READDIR): If DIR_HAS_FD_MEMBER is 0, ensure
  readdir.c gets compiled.
  * modules/readdir (configure.ac): Consider REPLACE_READDIR.
  --
  * lib/rewinddir.c (rewinddir): On mingw, redirect to the original
  rewinddir function. Prefer testing HAVE_DIRENT_H, for consistency with
  dirent.h.
  * m4/rewinddir.m4 (gl_FUNC_REWINDDIR): If DIR_HAS_FD_MEMBER is 0, ensure
  rewinddir.c gets compiled.
  * modules/rewinddir (configure.ac): Consider REPLACE_REWINDDIR.
  --
  * lib/fchdir.c (dir_info_t): Remove a FIXME.
