Add support for Parallels Desktop FS (prlfs) 

* mount.h (enum fs_info_type): Add prlfs (Parallels Desktop FS).
	(class fs_info): Add has_broken_fnoi flag.  Implement prlfs FS flag.
	* mount.cc (fs_info::update): Handle PrlFS.  Fill new has_broken_fnoi
	flag with life.
	(fs_names): Add prlfs.
	* globals.cc (ro_u_prlfs): Define.
	* path.h (path_conv::has_broken_fnoi): New method.
	* path.cc (symlink_info::check): Call file_get_fnoi utilizing new
	has_broken_fnoi filesystem flag.
	* fhandler_disk_file.cc (fhandler_base::fstat_by_handle): Ditto.

	* new-features.xml (ov-new2.3): Document Parallels Desktop FS support.
