bfe05ed4a6 touchpad: softbuttons: Deal with a click arriving before any touches
It is possible for a click to get reported before any related touch events
get reported, here is the relevant part of an evemu-record session on a T440s:

Notice the BTN_LEFT event all by itself!

To deal with this if a physical click registers before we get any touches,
wait for the first touch to resolve the click.

Also see the new activity diagram for the tp_post_softbutton_buttons
method which has been added to doc/touchpad-softbutton-state-machine.svg

55d84420e2 touchpad: Rework is_pointer handling
We don't want touches in the button area to cause the pointer to move. So
instead of making a touch the pointer when it moves to TOUCH_BEGIN, wait
with making it the pointer until its buttons state moves to BUTTON_STATE_AREA.

Note that a touch in the main area of the touchpad will move to
BUTTON_STATE_AREA immediately. If software-buttons are not enabled, any finger
is in the BUTTON_STATE_AREA.

While at it also refactor the is_pointer setting in general, removing
code duplicition wrt checking that another touch is not already
the pointer on unpinning a finger, and add safeguards that unpinning
does not make a finger which is not in button state BUTTON_STATE_AREA the
pointer, nor that the button code makes a pinned finger the pointer.

All these sanity checks are combined into a new tp_button_active function,
since they should be taken into account for 2 finger scrolling, etc. too.

e192ecc6e9 touchpad: Add clickpad-style software buttons
Almost all non Apple touchpads have visible markings for software button areas,
so limit clickfinger behavior to Apple clickpads, and implement software button
areas for others.

This is a slightly fancier implementation than the simplest model and ported
over from libtouchpad. It implements a state machine for the software buttons
with left and right buttons currently implemented. Buttons are oriented
left-to-right, in a horizontal bar. No random button placement allowed.

In general, the procedure is:
- if a finger sets down in the left button area, a click is a left click
- if a finger sets down in the right button area, a click is a right click
- if a finger leaves the button area, a click is a left click
- if a finger starts outside the button area, a click is a left click

Two timeouts are used to handle buttons more smoothly:
- if a finger sets down in a button area but "immediately" moves over
  to a different area, that area takes effect on a click.
- if a finger leaves a button area and "immediately" clicks or moves back into
  the area, the button still takes effect on a click.
- if a finger changes between areas and stays there for a timeout, that area
  takes effect on a click.

Note the button area states are named BOTTOM_foo to make it easier to later
add support for a top button area such as can be found on the Thinkpad [2-5]40
series.

604f22eb79 Introduce seat wide button and key count API
Compositors will need to keep provide virtual devices of supported
generic device types (pointer, keyboard, touch etc). Events from each
device capable of a certain device type abstraction should be combined
as if it was only one device.

For key and button events this means counting presses of every key or
button. With this patch, libinput provides two new API for doing just
this; libinput_event_pointer_get_seat_button_count() and
libinput_event_keyboard_get_seat_key_count().

With these functions, a compositor can sort out what key or button events
that should be ignored for a virtual device. This could for example
look like:

event = libinput_get_event(libinput);
switch (libinput_event_get_type(event)) {
...
case LIBINPUT_EVENT_POINTER_BUTTON:
	device = libinput_event_get_device(event);
	seat = libinput_event_get_seat(device);
	pevent = libinput_event_get_pointer_event(event);

	if (libinput_event_pointer_get_button_state(pevent) &&
	    libinput_event_pointer_get_seat_button_count(pevent) == 1)
		notify_pointer_button_press(seat);
	else if (libinput_event_pointer_get_button_state(pevent) &&
		 libinput_event_pointer_get_seat_button_count(pevent) == 0)
		notify_pointer_button_release(seat);
	break;
...
}
