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.

In some applications, notably Inkscape, where it is common to frequently drag
objects a short distance the default to drag-lock always-on is frustrating for
users.
Make it configurable, with the current default to "on".
New API:
libinput_device_config_tap_set_drag_lock_enabled
libinput_device_config_tap_get_drag_lock_enabled
libinput_device_config_tap_get_default_drag_lock_enabled
Any device capable of tapping is capable of drag lock, there is no explicit
availability check for drag lock. Configuration is independent, drag lock may
be enabled when tapping is disabled.
In the tests, enable/disable drag-lock explicitly where the tests depend
on it.

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.

Adds the following quartett of functions to enable/disable middle mouse button
emulation on a device:
libinput_device_config_middle_emulation_is_available()
libinput_device_config_middle_emulation_set_enabled()
libinput_device_config_middle_emulation_get_enabled()
libinput_device_config_middle_emulation_get_default_enabled()
This patch only adds the config framework, it is not hooked up to anything
yet.
Note: like other features this is merely the config option, some devices will
provide middle button emulation without exposing it as configuration. i.e. the
return value of libinput_device_config_middle_emulation_is_available() only
tells you whether you can _configure_ middle button emulation.

Some devices require more than just flipping around the buttons, such as
tablets.
When it comes to devices like tablets, because the position of the palm rest is
on the right, the entire tablet has to be flipped around in order to be usable
by lefties. As such, this requires that we reverse the coordinates of the
tablets in addition to flipping the buttons on the tablet. As such, renaming
these functions so that they aren't specific to devices where only the buttons
are flipped seems appropriate.

Sending separate axis events instead of one unified events is limiting,
especially when simultaneously scrolling in both directions and the caller
tries to implement kinetic scrolling.
Take a page from the tablet-support branch and instead implement the axis
event as a generic event that can contain multiple axes simultaneously.
Right now we only have two (scroll) axes and we could easily just check both
for non-zero values. If we want to allow further axes in the future, we need
a check whether an axis is set in an event, that's what
libinput_event_pointer_has_axis to scroll events() is for.
We also need the mask to notify of a scroll stop event, which could otherwise
be confused as a vertical-only or horizontal-only event.
This is an API and ABI break.
