* globals.cc (ro_u_refs): New R/O unicode string.

Browse Source 
* mount.cc (fs_info::update): Recognize ReFS.
	* mount.h (enum fs_info_type): Add refs.
	(class fs_info): Add refs flag and accessor methods.
	* ntdll.h (RtlAddAccessAllowedAceEx): Declare.
	(RtlAddAccessDeniedAceEx): Declare.
	* path.h (path_conv::fs_is_refs): Define.
	* sec_helper.cc (_recycler_sd): New function to create security
	descriptors suitable for the recycler bin starting with Vista.
	* security.cc (add_access_allowed_ace): Use RtlAddAccessAllowedAceEx
	and drop code to set AceFlags explicitely.
	(add_access_denied_ace): Use RtlAddAccessDeniedAceEx and drop code to
	set AceFlags explicitely.
	* security.h (_recycler_sd): Declare.
	(recycler_sd): Define.
	* syscalls.cc (desktop_ini): Change formatting.
	(desktop_ini_ext): Define third line of recycler desktop.ini file
	since Vista,
	(try_to_bin): Handle ReFS just like NTFS.  Write Vista and later
	Recycler in all uppercase, just like shell32 does when recreating it.
	Fix comments to include ReFS.  Don't implicitely reuse object
	attributes from earlier NtOpenFile call, rather recreate it for safety.
	Use recycler_sd call when creating security descriptor for Recycler
	dirs and files on Vista and later.  Write third line of desktop.ini
	when on Vista and later.
