We previously used the half-way mark of the touchpad's y axis to decide where
to ignore tapping. Move this down to the top edge of the software buttons
instead. Users may tap with a finger in the software button areas, on the rest
of the touchpad it's unlikely that they tap within 5% of the edge.
On touchpads with physical buttons or if clickfinger is enabled, the
no-tapping zone extends to the bottom of the touchpad. This required splitting
the tests into clickfinger, softbuttons and hardbuttons.

If the tablet is already in proximity on startup, we used to immediately sent
a proximity event. We can't fetch MSC_SERIAL from the kernel, so that tool
always had a serial of 0, followed by events with the real serial. Since
clients are supposed to use the serial for the tracking of tools, this is
suboptimal.
When the tablet is added, merely set the internal proximity flags. This way we
wait until the first real event from the device (which includes the serial
number) and convert that into a proximity event.

The firmware version is in id.version, not id.model which is always
PSMOUSE_ALPS for ALPS devices.
The various fw versions are listed in <kernel>/drivers/input/mouse/alps.h and
are all hex numbers. Version 8 is actually 0x800, change the match
accordingly.
Expected side-effect: earlier versions of ALPS touchpads now lose their
(erroneous) size assignment.

The Wacom tilt range is 64 degrees so we map everything into that until we
know otherwise.
This commit also switches the tilt axes around to align the angles with the
x/y orientation, i.e. tilting the top of the stylus towards the positive x
axis now generates a positive x tilt.

If dwt is disabled on the commandline, e.g. by setting an xinput property it
may be disabled before the release event comes in. This caused the timer to
refresh indefinitely since the key state mask was still on for that key.
Always updating the key state mask (even when dwt is disabled) fixes that.
If a key is held down while dwt is disabled, this can still cause a indefinite
timer refresh, so in the timer func, check if dwt is enabled before refreshing
the timer.

If a USB keyboard like the YubiKey is found before the internal keyboard, it
will be paired with the touchpad when it is seen. The internal keyboard is
seen later bug ignored because we already have a keyboard paired with the
touchpad.
This is obviously wrong. For now, give priority to serio keyboards, and
override existing dwt pairings with the new keyboard.

If a key enables dwt and is held down when the timeout expires, re-issue the
timeout.
There is a corner case where dwt may not work as expected:
1. key down and held down
2. dwt timer expires, dwt is re-issued
3. touch starts
4. key is released
5. dwt timer expires
6. touch now starts moving the pointer
This is an effect of the smart touch detection. A touch starting after the
last key press is released for pointer motion once dwt turns off again. This
is what happens in the above case, the dwt timer expiring is the last virtual
key press. This is a corner case and likely hard to trigger by a real user.

This was the reason for the valgrind test case failures whenever we
accumulated too many tests (see 9c2afae1 and 2a110104). The cause was simply
that we ran out of fds which caused libevdev to fail the scandir() searching
for the event node. That resulted in a NULL devnode and an abort in litest.
Close the fd before freeing the evdev device.

Some older touchpad devices jitter a fair bit when a finger is resting on the
touchpad. That's why the hysteresis was introduced in the synaptics driver
back in 2011. However, the default value of the hysteresis in the synaptics
driver ended up being 0, even though the code looks like it's using a fraction
of the touchpad diagonal. When the hysteresis code was ported to libinput it
was eventually set to 0.5mm.
Turns out this is still too high and tiny finger motions are either
nonreactive or quite jumpy, making it hard to select small targets. Drop the
default hysteresis by reducing its margin to 0, but leave it in place for
those devices where we need them (e.g. the cyapa touchpads).

This button sends a release N, press N+1 on each press, cycling through the
three event codes supported. This causes a stuck button since the current mode
is never released.
Long-term this better served by a set of switches that toggle accordingly, for
now disable the button codes.

There are a number of use-cases where tapping may be desirable, but
tap-and-drag is not, e.g. where tapping is used to select multiple items in a
list. Having tap-and-drag on hinders this, and the nature of the interaction
means it cannot be detected based on timeouts, movement thresholds, etc.
Provide an option instead to turn tap-an-drag off. Tap-and-drag remains
enabled by default (though tapping is disabled by default).
For the touchpad tap state diagram, the new option disables the transition
from state TOUCH to state TAPPED and releases the button immediately instead.
This means that multitap-and-drag is disabled too since we now just loop
around in the single-tap state for multitap.
It also makes tapping more responsive - we don't have to wait for the timeout
before we know whether it's a tap event. The first touch time is noted, we now
send the button press with the time of the first touch and the release with
the time of the release. This ensures a realistic time diff between the two
events.

When two fingers move slowly, an event frame may only have one finger motion,
followed by a frame with the other finger's motion. If we only divide by the
number of dirty touches, the speed of the gesture increases whenever that
happens.
