Modified files:
	winsup/cygwin  : ChangeLog autoload.cc dir.cc 
	                 fhandler_disk_file.cc fhandler_registry.cc 

Log message:
	Fix memory and handle leaks due to fdopendir:
	* dir.cc (closedir): Call global close instead of just releasing the
	fhandler.
	* fhandler_disk_file.cc (fhandler_disk_file::closedir): Don't close
	fhandler handle here, rely on global closedir doing the right thing.
	* fhandler_registry.cc (fhandler_registry::readdir): Also delete
	d_hash when closing registry key.
	(fhandler_registry::rewinddir): Ditto.
	
	Avoid infinite recursion in VirtualStore under UAC:
	* fhandler_registry.cc (VIRT_CLASSES_KEY_PREFIX): Define.
	(VIRT_CLASSES_KEY_SUFFIX): Ditto.
	(VIRT_CLASSES_KEY): Ditto.
	(VIRT_CLASSES_LINKTGT): Ditto.
	(fhandler_registry::exists): Return virt_symlink as file type if
	this is a Classes key under the VirtualStore.
	(fhandler_registry::fstat): Handle virt_symlink.
	(fhandler_registry::readdir): Return DT_LNK as d_type if this is a
	Classes key under the VirtualStore.
	(fhandler_registry::fill_filebuf): Handle Classes symlink.
	
	Handle user impersonation in /proc/registry access:
	* autoload.cc (RegOpenUserClassesRoot): Define.
	(RegOpenCurrentUser): Define.
	* fhandler_registry.cc (RegOpenUserClassesRoot): Declare function
	missing in w32api.
	(RegOpenCurrentUser): Ditto.
