A device with REL_X/Y and keys gets marked only as ID_INPUT_KEY, initializes
as keyboard and then segfaults when we send x/y coordinates - pointer
acceleration never initializes.
Ignore the events and log a bug instead. This intentionally only papers over
the underlying issue, let's wait for a real device to trigger this and then
look at the correct solution.

The previous approach to pointer acceleration was to initialize the same
motion filter behavior but a different acceleration profile depending on the
hardware (the profile converts a speed to a multiplier for input deltas).
To be more flexible for hardware-specifics, change this into a set of specific
pointer acceleration init functions. This patch has no effective functional
changes, they're still all the same.
The acceleration functions are kept for direct access by the ptraccel-debug
tool.

The previous code used a 5mm threshold before axis events were posted. This
threshold was on top of the 2mm 2fg threshold (and timeout handling) in the
gesture code and effectively prevented events from being sent after a timeout,
or in the 2mm-5mm range.
We still want a directional lock though, so split the two out. The default 5mm
threshold is set to 0 for touchpads since we have our own handling of the
threshold there. The directional lock only applies once scrollin has started
and remains on 5mm.

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.

To quote Bryce Harrington from [1]:
"MIT has released software under several slightly different licenses,
including the old 'X11 License' or 'MIT License'. Some code under this
license was in fact included in X.org's Xserver in the past. However,
X.org now prefers the MIT Expat License as the standard (which,
confusingly, is also referred to as the 'MIT License'). See
http://cgit.freedesktop.org/xorg/xserver/tree/COPYING
When Wayland started, it was Kristian Høgsberg's intent to license it
compatibly with X.org. "I wanted Wayland to be usable (license-wise)
whereever X was usable." But, the text of the older X11 License was
taken for Wayland, rather than X11's current standard. This patch
corrects this by swapping in the intended text."
libinput is a fork of weston and thus inherited the original license intent
and the license boilerplate itself.

In the original bug report[1], a Galago Ultra Pro was returned to the

model identified as MODEL_SYSTEM76_CLEVO.
Since the actual manufacturer of the W740SU is Clevo and the CLEVO hwdb

This way the unaccelerated deltas returned by libinput are correct.
To maintain the current behavior we slow down the input speed by the magic
factor and likewise the accelerated output speed. This produces virtually the
same accelerated deltas as the previous code.
The magic factor is applied to the default denominator for guessing a
resolution based on the touchpad diagonal. We can't really get around this
without having a resolution from the touchpad; meanwhile this produces
virtually the same coordinates before/after.
