* fhandler_disk_file.cc (fhandler_disk_file::readdir): Fix inode number

	evaluation for faked "." entry.

	* mount.cc (fs_info::update): Move setting of is_cdrom after checking
	for caseinsensitivity.  Recognize UDF in is_cdrom case and set
	caseinsensitive flag according to UDF brokenness determined by OS.
	Add comment to explain why.
	* mount.h (class fs_info): Add is_udf status flag.
	* path.cc (symlink_info::check): Add workaround for UDF bug in
	terms of casesensitivity on certain OSes.
	* wincap.h (wincaps::has_broken_udf): New element.
	(wincaps::has_broken_udf): New element
