The hwdb match entry used to be this one:
libinput:name:*Elan Touchpad*:dt:*
LIBINPUT_ATTR_PRESSURE_RANGE=10:8
from commit 596777a314. It was intended to match
for devicetree only but the way the udev rules were composed, it ended up
matching on any system.
Restore that for all systems to have compatibility with 1.11. For this one,
let's also add the resolution hint and hope that that works too.

All we do now is to set the fuzz, so we only ever need to care about this when

This was removed accidentally as part of a9ef4ba1f3 and then completely dropped in
870ddce9e4 when the hwdb was deprecated completely. The model quirks call
is also the one that reads and sets the LIBINPUT_FUZZ property, effectively
making that code a noop.

We may get a pointer jump on tip down/up, see #128. For absolute coordinates
we reset the history to avoid smoothing across that jump but deltas still used
to be calculated based on the previous position to the current one. This
can result in a large jump on tip down.
Since the delta is supposed to be useful (and not physically accurate, see the
docs), let's force it to 0/0 on tip down/up to avoid that scenario.

Because we're doing axis smoothing, we may get a nonzero delta between events
even when the real axis hasn't updated. Make sure the bit is set in this case.

On Dell i2c touchpads, the controller appears to go to sleep after about 1s of
inactivity on the touchpad. The wakeup takes a while so on the next touch, we
may see a pointer jump, specifially on the third event (i.e. touch down,
event, event+jump). The MSC_TIMESTAMP value carries a hint for what's
happening here, the event sequence for a touchpad with scanout intervals
7300µs is:
...
MSC_TIMESTAMP 0
SYN_REPORT
...
MSC_TIMESTAMP 7300
SYN_REPORT +2ms
...
MSC_TIMESTAMP 123456
SYN_REPORT +7ms
...
MSC_TIMESTAMP 123456+7300
SYN_REPORT +8ms
Note how the SYN_REPORT timestamps don't reflect the MSC_TIMESTAMPS.
This patch adds a quirk activate MSC_TIMESTAMP watching. When we do so, we
monitor for a 0 MSC_TIMESTAMP. Let's assume that the first event after that is
the interval, then check the third event. If that third event's timestamp is too
large rewrite the touches' motion history to reflect the correct timestamps,
i.e. instead of the SYN_REPORT timestamps the motion history now uses
"third-event SYN_REPORT timestamps minus MSC_TIMESTAMP values".
The pointer accel filter code uses absolute timestamps (#123) so we have to
restart the pointer acceleration filter when we detect this jump. This allows
us to reset the 0 time for the filter to the previous event's MSC_TIMESTAMP
time, so that our new large delta has the correct time delta too. This
calculates the acceleration correctly for that window.
The result is that the pointer is still delayed by the wake-up window (not
fixable in libinput) but at least it ends up where it should've.
There are a few side-effects: thumb, gesture, and hysteresis all still use the
unmodified SYN_REPORT time. There is a potential for false detection of either
of these now, but we'll have to fix those as they come up.

This function expected distances per-frame, not per-time which gives us
different behaviors depending on the hardware scanout rate. Fix this by
normalizing to a 12ms frame rate which reflects the touchpad I measured all
the existing thresholds on.
This is a bit of a problem for the test suite which doesn't use proper
intervals and the change to do so is rather invasive. So for now we set the
interval for test devices to whatever the time delta is so we can test the
jumps without having to worry about intervals.

This is mostly taken from the Weston Contributing.md document.
Main changes from there are:
- more detailed step-by-step on how to create a MR
- commit history/messages in two sections
- s/Weston/libinput/
I skipped the Review/Commit Rights sections for now until there's some demand
for it. Same with the Licensing/Stabilising for releases sections.

In testing on an Apple Magic Trackpad, thumb touches are reliably
detected by being quite large in the major dimension, but around
half the size in the minor dimension.
Use a boolean for whether we need to use it and drop the unneded absinfo

This forces events for every ~10ms now. If we want a slower movement, we need
more steps - just like a real touchpad does it.

The only test that needed a real fix was touchpad_no_palm_detect_2fg_scroll,
it used 12ms before, now it's using 10ms so on the bcm5974 touchpad the second
finger was a speed-thumb. Increasing the events and thus slowing down the
pointer means it's a normal finger and the test succeeds again.

The libinput context's user_data was used for deciding whether to grab the
event device but also to hold the struct window data for the debug-gui. Worked
fine for the initial batch of devices, but any device coming in late would
just use the first field of the struct window to decide whether to grab or
not.

anyway.

libinput applies averaging to the velocity of most pointer devices. Averaging
the velocity makes the motion look smooth and may be of benefit to bad input
devices. For good devices, however, it comes at the unfortunate price of
decreased accuaracy.
This change turns velocity averaging off by default (sets ntrackers to 2 instead
of 16) and allows for it to be turned back on via a quirk, for bad devices which
require it.
20 min for the "this docker image is ok" marker should be enough but not when
we're hit with random stuck containers in the next stage. By the time those
time out the artefacts have been removed and we now get a dependency error,
forcing us to re-run the whole pipeline.
Since the marker is only a few bytes, we can keep this for a bit longer
without risking running out of space.
