        _____________
       /

 /

where the x axis is the speed, y is the acceleration factor.
The first plateau is at the acceleration factor 1 (i.e. unaccelerated
movement), the second plateau is at the max acceleration factor. The threshold
in the code defines where and how long the plateau is.

This patch adjusts the curve based on a [-1, 1] range. For anything below 0,
the plateau is longer (i.e. accel kicks in at a higher speed), the second
incline is flatter (i.e. accel kicks in slower) and the max accel factor is
lower (i.e. maximum speed is slower). For anything above 0, the inverse is
true, acceleration kicks in earlier, harder and is faster in general. So the
default/min/max curves overlaid look something like this:
      ________ max

    | /  _____ min

Note that there are additional tweaks we can introduce later, such as

http://www.who-t.net/publications/hutterer2014_libinput_ptraccel_study.pdf

We found that there was little difference between the method we had in
libinput 0.6 and this three-line function. Users didn't really notice a
difference, but measured data suggests that it has slight advantages in some
use-cases.

The method proposed here is the one labeled "linear" in the paper, its profile
looks roughly like this:

        _____________
       /
  ____/

Differences to the previous accel function:
- both inclines are linear rather than curved
- the second incline is less steep than the current method

From a maintainer's point-of-view, this function is significantly easier to
