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

	* target.h (class process_stratum_target): Remove the target op.
	(struct process_target): Add the target op.  Also add
	'supports_read_auxv'.
	* target.cc (process_target::read_auxv): Define.
	(process_target::supports_read_auxv): Define.

	Update the derived classes and callers below.

	* server.cc (handle_qxfer_auxv): Update.
	(handle_query): Update.
	* linux-low.cc (linux_target_ops): Update.
	(linux_process_target::supports_read_auxv): Define.
	(linux_read_auxv): Turn into ...
	(linux_process_target::read_auxv): ... this.
	* linux-low.h (class linux_process_target): Update.
	* lynx-low.cc (lynx_target_ops): Update.
	* nto-low.cc (nto_target_ops): Update.
	(nto_process_target::supports_read_auxv): Define.
	(nto_read_auxv): Turn into ...
	(nto_process_target::read_auxv): ... this.
	* nto-low.h (class nto_process_target): Update.
