	(target_thread_name): Update the macro.
	(target_thread_handle): Update the macro.
	* target.cc (process_target::thread_name): Define.
	(process_target::thread_handle): Define.

	Update the derived classes and callers below.

	* linux-low.cc (linux_target_ops): Update.
	(linux_process_target::thread_name): Define.
	(linux_process_target::thread_handle): Define.
	* linux-low.h (class linux_process_target): Update.
	* lynx-low.cc (lynx_target_ops): Update.
