For a device used upside-down, make sure the wheels correspond to the
new physical directions. There's a grace range of 20 degrees either way
since that seems like it makes sense.
For 90 degree rotation (or 270 degree) the wheel is left as-is, the
heuristics to guess what angle we want in this case is not clear enough.

Adds a dedicated scroll movement type to the custom acceleration profile.
Supported by physical mouse and touchpad.
Other profiles remain the same by using the same unaccelerated filter for the scroll filter.

The IBM/Lenovo Scrollpoint mouse features a trackpoint-like stick that
sends a great amount of scroll deltas.
In order to handle the device, a quirk is in place to normalize the
scroll events as they were relative motion.
However, when high-resolution scroll was implemented, we started
normalizing the hi-res events instead of the lo-res events by mistake.
Fix the quirk by normalizing the right deltas.

Since cd4f2f32b5 ("fallback: disable mouse scroll wheel while middle
button is pressed") the mouse wheel is inhibited while the mouse wheel
is pressed.
The original intention of this feature was to avoid unintended scroll
while pressing the scroll wheel. However, now that high-resolution
scroll is fully integrated in libinput we can improve this feature and
filter unintended scroll (below half a detent) and allow it when it is
intended (over half a detent).
Remove the "WHEEL_STATE_PRESSED" state from the wheel state machine and
let the general heuristics handle this case.
Also, remove the specific tests for this feature as now it is covered
by the general test cases.

The device sends its own scroll events when its trackpoint is moved
while the middle button is pressed.
Because scroll events are not going to be inhibited after a certain
amount of scroll is detected in a follow up commit, remove the quirk.

Most mice with high-resolution support have a mechanism in place to
adjust the wheel to a detent. When scrolling, it is possible to stop
between two detents and this mechanism could generate a small amount of
scroll in the oposite direction.
Track the scroll direction in the wheel state machine and reset it when
the direction changes to avoid this issue.

Mice with high-resolution support can generate deltas when the finger is
put on the wheel or when the user tries to click the wheel.
To avoid sending involuntary scroll events, add an extra state the the
wheel state machine to accumulate scroll deltas.
While the accumulated scroll is lower than a certain threshold, ignore
them until the threshold is reached.
Since no finish event is sent by the mouse, reset the state machine
after a period of scroll inactivity.

In order to be able to add more complex rules in the future, transform
the current wheel handling code into a state machine.
