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.

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

Expected side-effect: earlier versions of ALPS touchpads now lose their

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.

(cherry picked from commit 0b0150e08d)
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.

(cherry picked from commit b27f04689e)
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 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.

Synaptics, Elantech and Alps semi-mt devices all have issues with reporting
correct MT data, even the bounding box which semi-mt devices are supposed to
report is wrong.
Synaptics devices have massive jumps with two fingers down. Elantech devices
may open slots without coordinate data. Alps devices may send 0/0 coordinates
as initial slot position.
All these may be addressable with specific quirks, but the actual benefit is
largely restricted to better palm detection (though even with quirks this is
unlikely to work) and support for pinch gestures (again, lack of coordinates
makes supporting those hard anyway).

(cherry picked from commit b3f11180e3)
open_restricted() doesn't always mean 'open the fd'. When the X server uses
systemd-logind, the fd is opened once before PreInit and then kept open across
devices being disabled and enabled through the protocol.
When the device is re-enabled and libinput_path_add_device is called for the
device, we may have events pending on the fd, leaking information that we
should just ignore.
There's also the potential of inconsistent state. The kernel updates the
device state whenever it processes an event, the evdev ioctls return that
state. If events are pending, the state we see is newer than the events we
process immediately after initialization. That can lead to confusion.
