bugref:8778: Double click not working with precision touchpad (user report)
Try to fix sending delayed button clicks to the PS/2 mouse device emulation.

We try to restrict input sent through the PS/2 mouse device to no more than
one packet every 50ms. To do this, we accumulate events. However we were
missing button clicks where both the press and the release occurred within
the timer interval. Additionally we were resetting the button to released
in some circumstances.
