* cygwin.din: Export fdopendir.

	* dir.cc (opendir): Call fhandler's opendir with fd set to -1.
	(fdopendir): New function.
	(seekdir64): Use dirent_info_mask.
	(rewinddir): Ditto.
	(closedir): Only release underlying file descriptor if it has been
	reserved by opendir itself.
	* fhandler.cc (fhandler_base::opendir): Accommodate new parameter.
	* fhandler.h (dirent_states): Add dirent_valid_fd and dirent_info_mask.
	(fhander_XXX::opendir): Add file descriptor parameter.  Use regparms.
	(fhandler_procnet::opendir): Drop declaration.
	* fhandler_disk_file.cc (fhandler_disk_file::opendir): Ditto.
	If called from fdopendir, use existing handle to re-open directory
	with valid flags.  Rename fd to cfd.  Use only if no valid incoming fd.
	(fhandler_cygdrive::opendir): Accommodate new parameter.
	* fhandler_process.cc (fhandler_process::opendir): Ditto.
	* fhandler_procnet.cc (fhandler_procnet::opendir): Drop definition.
