Without this, each finger movement happens in a different evdev event frame.
Since we average deltas for gestures, this messes with the expected data.

There's no test case where we need to do something immediately after the last
event so we might as well do everything in the same loop.
This also fixes a bug where the first movement would usually get swallowed.
Test cases in general put the finger down at x/y, then move them to some other
position. We'd expect the first event in a loop to happen at x+n/y+n, not at
x/y again.

We have two behaviors here:
- tap + 2fg -> scrolling
- tap + 1fg move + 2f down -> dragging
Let's document this. The 3fg case only has one situation, so let's test that.

Some users reported problems triggering multi-finger tap-and-drag,
with reliability decreasing as the finger count increased.
This is plausible because they may shift towards moving the whole hand
up and down, which obviously takes more time than just a finger.

The group names are forced by check (they are called suite names there) but
for our test suite they provide very little benefit. Much easier to just
use the filename a test is in as group name.
This removes the pure substring match for --filter-group, it's now fnmatch
only. group names are short enough that the typing isn't an issue and we don't
want to run tests twice (e.g. 'pad' is also in 'touchpad').

This is the device from

BTN_TOOL_PEN in addition to the real tool. Integrate this into the test device
proper so it always does this to catch various outliers.

The current tool type test merely sends BTN_TOOL_RUBBER (and others) manually
and expects libinput to do the right thing. This only tests the perfect
sequence but not test weird devices that behave differently on a tool type
switch.
So let's fix this by setting the tool type as property on the libinput test
device itself, and then emulate the tool switch through litest.
For special devices this will need extra callbacks, this is just the initial
framework to handle those buttons.

Putting an EVIOCGRAB on the device before sending those events means no-one
else sees those events - particularly upower. This means no-one else knows the
lid is on or off and thus we never blank the screen (or suspend/shut down but
those are inhibited anyway).

Take a snapshot of the time every 10 libinput_dispatch() calls. During event
processing, check if the event timestamp is more than 10ms in the past and
warn if it is. This should provide a warning to users when the compositor is
too slow to processes events but events aren't coming in fast enough to
trigger SYN_DROPPED.
Because we check the device event time against the dispatch time we may get
warnings for multiple devices on delayed processing. This is intended, it's
good to know which devices were affected.
In the test suite we need to ignore the warning though, since we compose the
events in very specific ways it's common to exceed that threshold
(particularly when calling litest_touch_move_to).

IMPORT really only supports == and != and for a short while udevd warned about
this before that warning was reverted again.
Where anything else is used, it falls back to ==. systemd upstream rules all
use a single = though, so let's stick with that to be consistent, even if it
is technically wrong (udevd will warn about this in debug mode).

Problem: it's still not a 100% check because the way real udev handles the
EVDEV_ABS overrides ignores any that are set through udev properties only. So
we manually have to trigger the keyboard builtin for our test device which
can give us false positives (e.g. it wouldn't have detected #424). But still,
it'll alert us if the actual overridden values are different to what we
expect.

check 0.13.0 introduced a new struct type TTest for test functions
instead of just a function. However, now the tcase_add_* functions use
`const Ttest *`, and since litest stores the test case in a `void *`,
we get warnings like the following:
../test/test-touchpad.c:7079:30: warning: passing argument 3 of '_litest_add' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
litest_add("touchpad:fuzz", touchpad_fuzz, LITEST_TOUCHPAD, LITEST_ANY);
To fix this, use `const void *`, which is compatible with both APIs.

The Wacom Cintiq 24HD and later tablets send specific key events for
hardware/soft buttons. KEY_PROG1..KEY_PROG3 on earlier tablets,
KEY_CONTROLPANEL, KEY_ONSCREEN_DISPLAY, and KEY_BUTTONCONFIG on later tablets.
We ignore KEY_PROG1-3 because starting with kernel 5.4 older tablets will too
use the better-named #defines.
These differ from pad buttons as the key code in itself carries semantic
information, so we should pass them on as-is instead of mapping them to
meaningless 0-indexed buttons like we do on the other buttons.
So let's add a new event, LIBINPUT_EVENT_TABLET_PAD_KEY and the associated
functions to handle that case.
Pad keys have a fixed hw-defined semantic meaning and are thus not part of
a tablet mode group.

libcheck has the ability to write out XML files for test results, but
converting those into junit isn't ideal, for a number of reasons:
- junit xml is different to libcheck's xml, so not all data is available or
useful. Especially with our litest wrappers around it.
- litest forking off tests means we have to wrap around everything anyway to
avoid multiple forks writing to the same test file.
This is the minimal implementation since it's only user is likely the CI which
we control fairly tightly. So there are a few corners we can skip:
- no filename validation is performed by litest
- we write out a lot of junit xml files (one per litest fork). Rather than
collating those we just rely on the CI to find the files.

In the current implementation, movements > threshold and timeouts usually move
to HOLD state and continue from there. Where a finger is lifted, we go back
up the diagram into the previous finger count's HOLD state.
The side-effect of this is that a tap of a finger can be counted as tap even
after a movement:
- two fingers down, move to scroll, hold down
- third finger down, third finger up
This sequence triggers an erroneous three-finger tap. Once the motion
threshold is hit by any touch, no finger must trigger 2/3 finger tap events
while any touch is down.
The false tap is only triggered where the new finger can execute a tap without
any other finger changing any property. This can be triggered on the
reporter's Dell Precision 5520 but on most other touchpads, a new finger down
will trigger slight movement, pressure or touch size updates and thus the bug
cannot be triggered.

Scroll button locking is an accessibility feature. When enabled, the scroll
button does not need to be held down, the first click holds it logically down,
to be released on the second click of that same button.
This is implemented as simple event filter, so we still get the same behavior
from the emulated logical button, i.e. a physical double click results in a
single logical click of that button provided no scrolling was triggered.

We can't run this in parallel so it doesn't gain us any speed advantage. If
anything, it'll be slower because it's more setup time in between. But: meson
doesn't display the result until the test suite finished, so having this
broken up into smaller chunks means we're more likely to see a general failure
early.
And the failure should be quicker to reproduce as well.

This device looks similar to a MT device on the kernel side, but it's not a
MT device and it's not quite a tablet either. It uses slots to track up to 4
totems off the same device and the only hint that it's not a MT device is that
it sends ABS_MT_TOOL_TYPE / MT_TOOL_DIAL.
udev thinks it's a touchscreen and a tablet but we currently init those
devices as touchscreen (because all wacom tablet touch devices are udev
tablets+tochscreens). So we need a quirk to hook onto this device.
And we use a completely separate dispatch implementation, because adding the
behavior to the tablet interface requires so many exceptions that it's easier
to just add a separate dispatch interface.
