Previously, we were nulling out the ArenaEntry in MultiDragPointerState too early, which was prevent MultiDragPointerState from rejecting the gesture in `dispose` if we hadn't accepted by the time the pointer went up. Now we properly reject the gesture, which causes the tap gesture to win during `sweep` in the arena. Also, add a bunch of docs and annotations based on information I learned while studying this issue. Finally, rename a private member of tap recognizer to a name that would have confused me less in my investigation. Fixes flutter#1186

put a comma after "processing" because otherwise it looks like the processing itself is done by "sweep", as opposed to the choosing of a winner.
