The only two callers passed in the fake resolution anyway, so we don't need
extra parameters here.
We don't allow devices with only x or y resolution set, either both or none.
And we can use libevdev_set_abs_resolution() rather than handling absinfo

Most thumbs are detected a few events into the sequence. Work this into parts
of the tapping state machine. Only the most common use-case is handled here -
if the first finger ends up being marked as a thumb, we return to the idle
state and ignore that touch sequence.
At any other state, we handle thumbs like any other finger.

All touchpad recordings seen so far show that a value above 100 is definitely
a thumb or a palm. Values below are harder to discern, and the same isn't true
for touchpads supporting ABS_PRESSURE instead of ABS_MT_PRESSURE.
The handling of a touch is as outlined in tp_thumb_detect:
* thumbs are ignored for pointer motion
* thumbs cancel gestures
* thumbs are ignored for clickfinger count
* edge scrolling doesn't care either way
* software buttons don't care either way
* tap: only if thumb on begin
The handling of thumbs while tapping is the simplest approach only, more to
come in follow-up patches.
Note that "thumb" is the synonym for "this touch is too big to be a
fingertip". Which means that a light thumb touch will still be counted as a
finger. The side-effect here is that thumbs resting a the bottom edge of the
touchpad will almost certainly not trigger the pressure threshold because
most of the thumb is off the touchpad.

The touchpads currently all send a default value of 30 for ABS_PRESSURE. For
some tests we want to have a custom pressure but changing all tests isn't
sensible. So hook each device up to send a default value of 30 if it isn't
overridden in the test itself.

Watching a colleague try clickfinger right-click after enabling it the first
time showed that the vertical distance is too small. Increase it to 30mm
instead.
Increase the allowed spread between fingers to 40x30mm, but check if one of
the fingers is in the bottom-most 20mm of the touchpad. If that's the case,
and the touchpad is large enough to be feasable for resting a thumb on it,
discard the finger for clickfinger count.
If both fingers are in that area or one finger is in the area and they're
really close together, the fingers count separately and are not regarded as
thumb.

Extend the touchpad gesture API with pinch gestures. Note that this
new API offers a single event stream for both pinch and rotate data, this
is deliberate as some applications may be interested in getting both at
the same time. Applications which are only interested in one or the other
can simply ignore the other.

For touchscreens we always send raw touch events to the compositor, and the
compositor or application toolkits do gesture recognition. This makes sense
because on a touchscreen which window / widget the touches are over is
important context to know to interpret gestures.
On touchpads however we never send raw events since a touchpad is an absolute
device which primary function is to send pointer motion delta-s, so we always
need to do processing (and a lot of it) on the raw events.
Moreover there is nothing underneath the finger which influences how to
interpret gestures, and there is a lot of touchpad and libinput configuration
specific context necessary for gesture recognition. E.g. is this a clickpad,
and if so are softbuttons or clickfinger used? What is the size of the
softbuttons? Is this a true multi-touch touchpad or a semi multi-touch touchpad
which only gives us a bounding box enclosing the fingers? Etc.
So for touchpads it is better to do gesture processing in libinput, this commit
adds an initial implementation of a Gesture event API which only supports swipe
gestures, other gestures will be added later following the same model wrt,
having clear start and stop events and the number of fingers involved being
fixed once a gesture sequence starts.

Since 69449ca854, the minimum deceleration is 0.3 and we don't get a 0 motion
event anymore. We can drop the helper function now too.
What we do in that test instead is pump one relative motion event through
before we start comparing the events, this way our second, third, .. events
will have some acceleration applied and the tests compare more accurate
values.
