When the loop was reduced to BTN_DIGI only, it guaranteed that the BTN_STYLUS
condition was no longer met.

The latter has more obvious handling of hwdb matches. With udevadm hwdb a glob
may take precedence over a hwdb entry even if the latter is sorted later.

These numbers just happened to add up correctly for the motion history to
produce a zero delta for a diagonal movement. Fix it by adding extra events to
flush out any motion history leftovers.

This test had a loop around the proximity events, so in theory we could've
sent two proximity-in events and still get a positive test.

The totem, also a tablet tool, is a tool that is always tip-down and does not
support hovering so we need to be able to distinguish this for tests.

The Dell Canvas Totem only has the MT axes but not the single touch ones. Make
sure we copy the axis extents correctly.

On the Dell Canvas Totem, the tool will cancel existing touch points and to
visually debug that, we need the touchpoints to be drawn over the tool.

Buttons that aren't lmr are drawn in a separate button square now with the
name as it comes from the kernel. This only handles one button at a time, but
it'll do for debugging.

The old one is deprecated (and removed), new one is archlinux/base which also
now requires the diffutils package.
The new one apparently doesn't come with /var/cache/pacman/pkg and it's
not created, so pacman clean exits with an error, breaking the build.
Simply create that directory and everything is hunky, though dory remains
elusive.

When the touch arbitration is reset to ARBITRATION_NOT_ACTIVE, the proximity
timer is set for 90ms to avoid erroneous touches (see 2a378beab for the
reason).
If the device is removed within those 90ms, the timer is never cancelled,
leading to an assert on cleanup.

On the Asus Vivobook Flip 14, the tablet mode switch is unreliable and always
on. Instead of marking every device as 'do not suspend', just mark the tablet
switch itself.

If the tilt angle on tip down is not 0 set the touch arbitration to a
rectangle around the assumed position of the hand. This assumed position is
right of the tip for a rightwards tilt and left of the tip for a leftwards
tilt (i.e. left-handed mode). The rectangle is 200x200mm with a 20x50mm
NW of the tip or NE for left-handed. In other words, if the period below is
the tip, the rectangle looks like this:
+-----------+ +-----------+
| . | <- for rightwards tilt | . |
| | | |
| | | |
| | for leftwards tilt -> | |
+-----------+ +-----------+
Touches within that rectangle are canceled, new touches are ignored. As the
tip moves around the rectangle is updated but touches are only cancelled on
the original tip down. While the tip is down, new touches are ignored in the
exclusion area but pre-existing touches are not cancelled.
This is currently only implemented in the fallback interface, i.e. it will
only work for Cintiqs.

This enables us to specify the location that needs to be arbitrated, rather
than just disabling the whole device altogether. This patch just adds the
hooks, no implementation.
This is internal API only, one backend can specify an area in mm which gets
converted to device coordinates in the target device and arbitrated there.
Right now, everything simply passes NULL.

If we don't have tool-based palm detection, make sure our touch is labelled as
"not palm" during touch down. Otherwise that slot remains on palm forever if
it gets tagged as palm through some other means.
This currently has no effect, nothing in the code would label the touch as
palm. This is prep work for better touch arbitration.

This enables us to change the types of touch arbitration, with the focus on
allowing location-based touch arbitration as well as the more generic "disable
everything".

When a hand is resting on a pen+touch device, lifting the hand may remove the
stylus from proximity before the hand leaves the surface. If the kernel
performs touch arbitration, this triggers a touch down on proximity out,
followed by a touch up immediately after when the hand stops touching.
This can cause ghost touch events. Prevent this by using a timer-based
arbitration toggle.
Same as 2a378beab0 but for the fallback
interface.

This leaves a bug open, on a Lenovo T440 generation touchpad with top software
buttons, the button will not be leased correctly. This is caused by
device->is_suspended=true by the time we try to clear the state and the
button events thus getting filtered.
This used to affect all touchpads, this patch just moves it so it only affects
the T440-like devices now.
