Apple touchpads don't use ABS_MT_PRESSURE but they are multitouch touchpads,
so the current pressure-based handling code doesn't apply because it expects
slot-based pressure for mt touchpads.
Apple does however send useful data for ABS_MT_WIDTH_MAJOR/MINOR, so let's use
that instead. The data provided in those is more-or-less random, so we need a
hwdb entry to track the acceptable thresholds.

The max values on ABS_MT_TOUCH_MAJOR/MINOR aren't hard limits, they basically
represent the size of a finger with (afaict) a suggestion that anything
greater than the max may be a palm. Disable the 0-100% range checks for those
axes so we can send custom events.

This was useful when we had a small number of test-forks with the suites

Broken since the merge of palm pressure detection in
25d54b90d, not sure why the test suite succeeded on that one nonetheless.
I'm not 100% sure why the test does what it does but it seems to be testing
that a wide touch on the side still striggers edge scrolling and not the thumb
detection on the bottom of the touchpad. That is obsolete now, it's hard to
generically figure out the small gap between thumb and palm pressure, so this
test almost always triggers palm detection. It's obsolete.

We used to completely ignore a finger that was within the top software button
area and then moved to the main area and remained there for a timeout. This
avoids erroneous pointer movements when the user moves the finger while using
the trackpoint.
But we also ignored physical clicks, something we should not be doing. This
patch fixes that behavior: we still ignore the finger for movement, but a
physical click now triggers a left click once we've been in the area for the
timeout.
This new behavior doesn't apply within the timeout, i.e. if a finger is in the
right top button area, moves out and immediately clicks, we still trigger a
right click. This avoids erroneous switches to left-clicks when the finger is
at the edge of the button area and moves out during the press.

If a touch goes past the fixed pressure threshold it is labelled as a palm and
stays a palm. Default value is one that works well here on a T440 and is
virtually impossible to trigger by a normal finger or thumb. A udev property
is exposed so we can handle this in the udev hwdb and the new tool introduce a
few commits ago can help finding the palm detection threshold.
Unlike the other palm detection features, once a palm goes past the threshold
it remains a palm until the touch is released. This means palm overrides any
other palm detection features. For code simplicity, we don't combine the
states but merely check for pressure before and after the other palm detection
functions. If the pressure triggers, it will trigger before anything else. And
if something else is already active (e.g. edge where the pressure doesn't work
well) it will trigger as soon as the palm is released.
The palm threshold should thus be chosen with some room to spare between the
highest finger pressure.

Do so on the synaptics serial touchpads at least, they're known to cause
cursor jumps when the third finger is down. Not detecting a tap move means
three-finger taps get more reliable on these touchpads.
This change affects gestures who now effectively have to wait for the tap
timeout to happen. It's a trade-off.

Check arranges the tests into suites and test cases (which then can have
multiple test functions). The primary feature for suites is the ability to
select them with environment variables and that the log messages are printed
per suite, not per test case.
We used the suites to distribute tests across the processes forked by the test
runner, but that also resulted in slow suites relying on timeouts (tap/dwt) to
take a lot longer than other suites and hold everything else up.
This patch basically drops the use of check test suites. Our test runner has a
--filter-group argument which selects on suite names, the log messages are
more useful if they immediately include the device and the test case name.
So we just save the test metatdata in our own struct and then assemble a
suite/test case on the fly for each test.
The advantage of this is that tests of the same suite are now distributed
across the forks so slow tests that rely on length timeouts are now run in
parallel. This brings the test runs down to under 6 min again.

This makes it possible to run multiple test suite simultaneously on the same
host without messing up the other runs (provided that all instances use
the same udev/hwdb files). Previously, removing the udev rules/hwdb at the end

This explains the heisenbugs when running the test suite. libevdev gives us
the syspath to the /sys/.../input123 node, not the one for the event node.
The device node path is created based on the sysfs tree, so there's a
window where the device node may not exist yet but we already returned the
device node path.
In litest, we're using a udev monitor to wait until the device is ready for
us, but the path interface only takes a device node path. So what happens is:
* libevdev gives us a syspath for the input node and a device path
* the monitor receives the input node udev device and matches the syspath
* we pass that up to the caller litest_add_device_with_overrides()
which opens the device node and adds it to libinput
* the path interface creates a udev device from the device node, which still
points to the old device node. Things fail because we don't have the device
we expect or it doesn't send events and eventually times out [1].
The errors triggered by this are either odd udev property mismatches or
timeouts because events are never processed.
This race is fixed by simply constructing the actual device node path we
expect from the udev device and waiting for the right device.
[1] We rely on the caller to notify us when to remove the device and thus
silently ignore ENODEV.
