	* select.el: allow x-set-selection to take a buffer object that is
	inspected on-demand to obtain selection data from its region.

	* mouse.el: fix time-ordering of deactivate-mark operations in
	mouse drag tracking. Avoid doubling of selection in
	mouse-yank-primary when select-active-regions is on.
