	Turn process_stratum_target's join op into a method of
	process_target.

	* target.h (struct process_stratum_target): Remove the target op.
	(class process_target): Add the target op.
	(join_inferior): Update the macro.

	Update the derived classes and callers below.

	* linux-low.cc (linux_target_ops): Update.
	(linux_join): Turn into ...
	(linux_process_target::join): ... this.
	* linux-low.h (class linux_process_target): Update.
	* lynx-low.cc (lynx_target_ops): Update.
	(lynx_join): Turn into ...
	(lynx_process_target::join): ... this.
	* lynx-low.h (class lynx_process_target): Update.
	* nto-low.cc (nto_target_ops): Update.
	(nto_process_target::join): Define.
	* nto-low.h (class nto_process_target): Update.
	* win32-low.cc (win32_target_ops): Update.
	(win32_join): Turn into ...
	(win32_process_target::join): ... this.
	* win32-low.h (class win32_process_target): Update.
