* security.cc (set_file_sd): Drop using FILE_OPEN_FOR_RECOVERY flag in

	call to NtOpenFile.
	* exceptions.cc (open_stackdumpfile): Ditto in call to NtCreateFile.
	* fhandler.cc (fhandler_base::open): Ditto.  Simplify setting
	create_options.

	* mount.cc (fs_info::update): Recognize offline storage.
	(fillout_mntent): Report UDF and offline storage.
	* mount.h (class fs_info): Add is_csc_cache status flag.
