Hans de Goede cab012eefe touchpad: Add tap suspend / resume 
While e.g. disabling the touchpad while the trackpoint is used, we want to
stop sending tap (or scroll or motion) events. We cannot use tp_clear_state at
this time as that will also release any touchpad buttons pressed, breaking
dragging with the trackpoint using the touchpad or clickpad buttons.

Calling tp_release_all_taps() and then ensuring that we do not call
tp_tap_handle_state as long as the trackpoint is in use, is enough to disable
taps when the trackpoint is in use.

However when the trackpoint stops being used, we cannot simply start calling
tp_tap_handle_state() again, we first need to sync the tap.state to the current
reality, specifically if fingers are down it must be TAP_STATE_DEAD, so that
their releases do not trigger the log_bug_libinput on a release in
tp_tap_idle_handle_event.

Directly messing with tap.state from outside evdev-mt-touchpad-tap.c is not
good, so add tp_tap_suspend and tp_tap_resume functions for this.

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:
