Gnulib module: fdopendir

Portability problems fixed by Gnulib:
@itemize
@item
This function is missing on some platforms:
glibc 2.3.6, MacOS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, AIX
5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Cygwin 1.5.x, mingw, Interix 3.5, BeOS.
But the replacement function is not safe to be used in libraries and
is not multithread-safe.  Also, the replacement does not guarantee
that @samp{dirfd(fdopendir(n))==n} (dirfd might fail, or return a
different file descriptor than n).
@item
This function exists but is not declared on some platforms:
FreeBSD 7.3.
@item
This function does not reject non-directory file descriptors on some
platforms:
GNU/Hurd.
@item
This function mistakenly closes non-directory file descriptors on some
platforms:
FreeBSD 8.1.
