* cygheap.cc (cwcsdup): New function.

	(cwcsdup1): New function.
	* cygheap.h (cygheap_user::get_windows_id): New method returning PWCHAR.
	(cwcsdup): Declare.
	(cwcsdup1): Declare.
	* registry.cc (get_registry_hive_path): Use WCHAR instead of char
	throughout.
	(load_registry_hive): Ditto.
	* registry.h (get_registry_hive_path): Change declaration accordingly.
	(load_registry_hive): Ditto.
	* sec_helper.cc (cygpsid::string): New method returning PWCHAR.
