Hans de Goede 7a64815faa touchpad: Make tap code follow state machine diagram part 1 
According to the diagram, we should only check the tap-touch-state before
sending a button press / release when in state touch_2 or touch_3.

tp_tap_notify always checks the tap-touch-state. This is problematic when in
state tapped, or one of the follow up states, since this could cause the
button 1 release to never happen.

In practice this is never a problem since the touch passed into tp_tap_notify
is NULL when called for timeout or button events, and in the 2 affected paths
where we're dealing with a touch or release tap-touch-state always is
TAP_TOUCH_STATE_TOUCH.

However we should not rely on this and properly follow the diagram, this
commit therefor drops the touch argument to tp_tap_notify, and adds explicit
tap-touch-state checks in the places where they are present in the diagram too.

libinput

libinput is a library that handles input devices for display servers and other
applications that need to directly deal with input devices.

It provides device detection, device handling, input device event processing
and abstraction so minimize the amount of custom input code the user of
libinput need to provide the common set of functionality that users expect.

Input event processing includes scaling touch coordinates, generating
pointer events from touchpads, pointer acceleration, etc.

libinput originates from weston, the Wayland reference compositor.

The source code of libinput can be found at:
