Previously, any lower finger spaced more than the vertical threshold apart
would be labelled as thumb. This causes some taps to be detected as
single-taps, particularly where the user's hand is at an angle that causes the
touches to be effectively vertical.
Restructure that condition so that we only go for a thumb if we're
distinctively apart, and we only *not* go for thumb if we're distinctively
close together.

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.

Positive side-effect - this exposed a bunch of missing #includes that got
pulled in by other headers before.

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.

These tests include string parsers, definitely want those to run under
valgrind to detect OOB reads and writes.

The quirks for each device are listed in the recording but they may not apply
during libinput replay (e.g. for DMI matches). Work around this by writing out
the local-overrides.quirks file before initializing the devices. This way
we're guaranteed that the device is identical as on the reporter's machine.

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
is bound to trigger some little issues eventually that should be triggered
explicitly, not by accident.

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.
