Our udev callout is supposed to reset the kernel fuzz to 0 and move the value
to the LIBINPUT_FUZZ property. This is to stop the kernel from applying its
own hysteresis-like approach.
Where the kernel fuzz is nonzero, something has gone wrong with that approach.
Complain about it and set our fuzz to zero, we are in the hands of the kernel
now. If we leave our fuzz as nonzero, we'll apply our own hysteresis on top of
the kernel's and that leads to unresponsive behavior.

We generate litest-specific udev rules that contain the path to the binaries
in the builddir. But litest wasn't using those, so IMPORT would run things in
/usr/lib/udev instead. Thus any changes to those binaries generated false test
results depending on how compatible the system-installed libinput was.
This is why 410b157 passed the test suite for example.

And when that happens, skip the tests because what's happening here is that
you're running tests as root, but your X server doesn't allow root to connect.

We don't have a hysteresis for tablet devices, so let's leave those as-is.
This may be a slight regression in behavior compared to pre-410b157e84 now the
kernel will apply the fuzz. Let's see if anyone notices, the fuzz is usually
so tiny on tablets that it shouldn't be noticable.

If the libwacom context failed to initialize for some reason, the database is
NULL and the refcount remains at zero. Calling unref should just work then.

If we don't handle a device, don't touch it. Especially joysticks that we
don't handle and thus should not touch either.

This causes a regression - the ID_INPUT_* properties are not available through
libudev within a callout, the device we get here basically has no properties.

This reverts commit 410b157e84.
The previous movement was one finger still, the second finger moving. This may
cause axis events to trigger when a 2fg scroll gesture was detected. Those
axis events will stop after the gesture timeout but generate one more axis
stop event.
Make two changes here: first, move the fingers like a proper 2fg scroll
motion. And shuffle around the litest_drain_events() calls to ignore any axis
event immediately after the timeout.

This test worked because no gesture was detected in the initial movement.
If that happens though, releasing one finger triggers the gesture timeout
during which we suppress events, thus failing the test. Fix this by moving,
waiting, moving - that will definitely generate an event.

Second finger's x coordinate was wrong. That we didn't pick this up as pinch
is quite telling too.

If we're testing for this, let's not try to get it picked up as pinch

We only care about the third-finger data here, the movement of the first two
was just to get out of the base tap states. A timeout will do the same thing
here.

I don't think there was a specific reason for the second touch point to jump
around here either and the comment indicates it was just to avoid the
clickfinger distance trigger. So let's just move the first touchpoint.

If the fingers are in the position in the current code, that's not a 3fg
click, that's a pinch. Let's use something more realistic.

This test was putting both fingers down in the thumb area. That's not
representative, it's more likely that a thumb is in the area and the second
finger clicks elsewhere. So let's test for that instead.

These were supposed to test the thumb area, but the pressure exceeded the
threshold for most devices, thus ending up testing the palm detection instead.
Fix to use a timeout where possible, otherwise move them to the palm detection
code instead.

This pen has random timeouts, often when a button is pressed. This causes a
forced proximity out (and the button release) and makes the whole device a
tad unusable.
Nothing we can detect by heuristics since it looks like other devices that
don't send proximity out events. And the timeout can be quite high, the
recording in #304 has over 800ms for one sequence.
Fixes#304

Where the proximity out event is delayed by the kernel, libinput would cause
an extra proxmity in-out after the forced proximity out event.
Event sequence is basically (k: kernel, l: libinput)
k: tablet axis events
l: tablet axis events
k: nothing for $proximity timer milliseconds
l: tablet proximity out
k: proximity out event
l: proximity in event
l: proximity out event

__builtin_popcount might not be available and in this case, a bitwise-and
can accomplish the same task.
Signed-off-by: Michael Forney <mforney@mforney.org>
__builtin_popcount might not be available on all compilers, so using
it requires a configure check and fallback implementation. In fact
on gcc without an -march flag, it gets compiled to a function call to
libgcc. However, we only need to test whether multiple bits are set,
and this can be done easily with a bitwise and.

We only ever set properties in the devices, so let's make that more explicit
and auto-generate the udev rule. This way we're hopefully better protected
from the various typos that hid in those rules over the years, but also be
prepared for passing the udev property key/value pairs elsewhere.

This escaped us before because the MOUSE_DPI setting on the low-dpi device was
