Where a fuzz is defined in the 60-evdev.hwdb, we rely on a udev builtin to
set the kernel device to that fuzz value. Unfortunately that happens after our
program is called with this order of events:
1. 60-evdev.rules calls IMPORT(builtin) for the hwdb which sets the EVDEV_ABS_*
properties. It also sets RUN{builtin}=keyboard but that's not invoked yet.
2. 90-libinput-fuzz-override.rules calls IMPORT{program} for our fuzz override
bits. That sets the kernel fuzz value to 0 and sets the LIBINPUT_FUZZ_*
propertie
3. The keyboard builtin is run once all the rules have been processed.
Our problem is that where the fuzz is set in a hwdb entry, the kernel fuzz is
still unset when we get to look at it, so we always end up with a fuzz of zero
for us and a nonzero kernel fuzz.
Work around this by checking the EVDEV_ABS property, extracting the fuzz from
there and re-printing that property without the fuzz. This way we ensure the
kernel remains at zero fuzz and we use the one from the hwdb instead.

libinput-util.h is getting a bit of a catchall bucket and it includes things
like libinput-private.h which in turn includes libwacom. This makes
libinput-util.h less useful for bits that only need e.g. the string processing
utilities.
So let's split them all up in to separate files, to be used as-needed.

Allowing gestures when holding a physical click enables tasks like
switching workspaces while dragging an icon, but this should only be
possible with a *thumb* holding down the clickpad, not fingers. This
commit restores the ability to hold down the clickpad with two or three
fingers to right- or middle-drag.

Pens that don't have a pressure offset (caused by a worn-out tip) still have
basic pressure thresholds to avoid tip events when we're still a bit away from
the tablet or barely touching it. That range is currently 5% of the pressure
for tip down, 1% for tip up.
This leaves us with 95% of the range and that needs to be scaled correctly,
otherwise the bottom 5% happen before a tip event and are inaccessible where
applications don't look at pressure before tip down.

Theoretically this shouldn't matter, but testing at the far end of the range

Previously, the pressure range was calculated from the axis total range. A
device with a pressure offset making the bottom 10% inaccessible would lose
10% of that range as non-accessible. Due to the implementation, this affected
the upper range of the device, so the top N percent became unaccessible. Which
may be why no-one's noticed this yet.

Unsuprisingly, a normalized [0,1] value will always be between 0 and 1, so
bhis gave us a false positive. Check for the real values instead.
Those values aren't 100% correct because of a bug in the offset handling which
will be fixed in a follow-up commit. The difference is near enough that it
doesn't matter here anyway.

In evdev_device_calibrate, the user matrix was not being stored when it
was the identity matrix. This resulted in
libinput_device_config_calibration_get_matrix not providing the correct
matrix. Instead of giving the identity matrix, the last non-identity
matrix set was given.
This just moves the storage of the user matrix in
evdev_device_calibrate to be above the identity matrix early return so
that it always get stored.

We keep running into the proximity timeout for these tests, especially under
valgrind. To avoid this, manually intersperse the touch events with tablet
events.
Note that this manual loop would just work even without tablet events
because we no longer have a 10ms delay between touch events as enforced by
litest_touch_move_to. But let's do the right thing anyway.

Instead of a simple yes/no/maybe for thumbs, have a more extensive state
machine that keeps track of the thumb. Since we only support one thumb anyway,
the tracking moves to the tp_dispatch struct.
Test case changes:
touchpad_clickfinger_3fg_tool_position:
with better thumb detection we can now handle this properly and expect a
right button (2fg) press for the test case
touchpad_thumb_no_doublethumb_with_timeout:

When a touchpad has thumb detection enabled, avoid false-positive gestures
involving a resting thumb by using two thresholds: inner and outer.
While both touches remain inside their inner thresholds, remain in UNKNOWN
state to allow for accurate gesture detection even with no timeout.
If both touches move outside their inner thresholds, start a pinch or
swipe/scroll gesture according to direction, as usual.
If one touch moves outside its outer threshold while the other has not yet
exceeded its inner threshold, and thumb detection is enabled, then if one
touch is >20mm lower, mark it as a thumb and cancel the gesture.

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.

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.

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.

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.
