This adds support for GestureDetector.onLongPressDown and
GestureDetector.onLongPressCancel, allowing callers to register
interest in the initial pointer contact that might turn into
a long-press (and the associated cancel event if the gesture
loses).

This reverts commit 437ff210.

It was incorrectly resetting state when it received a
non-allowed pointer but had already accepted a gesture.
