[ANNOUNCE] libinput 0.15.0

[Peter Hutterer]

A new release of libinput, 0.15.0, is now available. 

One new API was added: libinput_device_keyboard_has_key() which does what it
says on the box.

A new tool is now available: libinput-debug-events
This tool allows debugging libinput events directly, it works as something
like an evtest to libinput. Note that it is very much a debugging tool only,
do not rely on any specific behavior or output format.

A new udev property POINTINGSTICK_CONST_ACCEL is now supported for
pointing sticks. If set for a compatible device, the input data is
multiplied with a constant factor. Pointing sticks vary greatly across
devices and often feel very different to a mouse or touchpad, this property
is to make them roughly the same so that a single acceleration setting is
appropriate for both mice and pointing sticks.

We've added support for the LIBINPUT_MODEL_xzy udev tag. This enables us to
tag specific models or series in udev and apply required quirks. First to
use that is the Lenovo X230T which has a broken touchpad and needs a custom
acceleration method to be useable.
Another use of model-specific configuration: clickfinger behavior is now the
default on Chromebooks and some System76 laptops to match the vendor
defaults.

A couple of bugfixes, mainly in the touchpad code. The doubletap timeout is
now longer but multi-tapping is generally more responsive now.
Clickfinger behavior was fixed to allow left-clicks even when a touch isn't
present on the device. This is particularly useful for standalone touchpads
like the Logitech T650.

Button scrolling is enabled by default on some devices now, specifically on
devices without a scroll wheel but with a middle button.

A final note to answer the question: where is 1.0?
We've had a few bugs reported that simply shouldn't be in a 1.0, like the
doubletap timer bug. So for now I'm keeping the numbers at 0.xy until those
are ironed out. The ABI is stable, so it shouldn't matter what magic number
we assign anyway.

As usual, the git shortlog is below.
