* target.h (struct target_ops): Replace "to_read_partial" and
	"to_write_partial" with "to_xfer_partial".  Update comments.
	* target.c (debug_to_write_partial): Delete function.
	(debug_to_xfer_partial): Replace debug_to_read_partial.
	(add_target, update_current_target, setup_target_debug): Set
	"to_xfer_partial" instead of "to_read_partial" and
	"to_write_partial".
	(default_xfer_partial): Replace "default_write_partial".
	(default_read_partial): Delete.
	(target_read_partial, target_write_partial): Call
	"to_xfer_partial".
	* remote.c (init_remote_ops): Set "to_xfer_partial".
	(init_remote_async_ops): Ditto.
	(remote_xfer_partial): Replace "remote_read_partial".
