Part of the big revamp to get rid of libinput_tablet_tool_axis and
replace it with a set of axis-specific APIs.
Only the rel wheel has true delta events, everything else is a delta
calculated by libinput based on the previous position. Since we supply that
position to the callers anyway, they can determine that delta themselves
where needed.

Part of the big revamp to get rid of libinput_tablet_tool_axis and
replace it with a set of axis-specific APIs.
Note that this commit drops the ability to check whether a tablet has an x or
y axis. If it doesn't, libinput won't initialize the tablet anyway so this was
superfluous already.
Likewise with the tilt axes - either we have x and y tilt or we have neither,
so separate checks for tilt_x and tilt_y is unnecessary.

Second part of the big revamp to get rid of libinput_tablet_tool_axis and
replace it with a set of axis-specific APIs.
Note that this commit drops the ability to get the absolute value from a
relative wheel. The previous API always returned 0 for this case, it is not
needed anymore.

The tablet tip works like a button in the kernel but is otherwise not really
a button. Split it into an explicit tip up/down event instead.

DWT can interfere with some applications where keyboard and touchpad use at
the same time is common, e.g. games but also anything that requires a
combination of frequent pointer motion and use of keyboard shortcuts.
Expose a toggle to disable DWT where needed.

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.

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.
