Exposed via new configuration option this enables 3 and 4 finger
dragging on touchpads. When enabled a 3/4 finger swipe
gesture is actually a button down + motion + button up sequence.
If tapping is disabled the drag starts immediately, if tapping is
enabled the drag starts after the tap timeout/motion so we can distinguish
between a tap and a drag.
When fingers are released:
- if two fingers remain -> keep dragging
- if one finger remains -> release drag, switch to pointer motion
When 3/4 fingers are set down immediately after releasing all fingers
the drag continues, similar to the tap drag lock feature. This drag lock
is not currently configurable.
This matches the macos behavior for the same feature.

This adds the configuration option to define a rectangle that serves as
an input area on external tablets such as an Intuos.
The intention behind this is to make this input area behave as if it was
the only physical input area on this tablet with libinput emulating
proximity events as required for where the tools moves in and out
of this area.
This could also be achieved with the existing calibration setting but
area configuration is not calibration and we don't want to expose other
side-effects of the matrix (e.g. scaling and rotation) for these
devices.

Add a configuration option to reduce the available hardware range to a
fraction thereof. This is done by copying the absinfo struct for the
pressure value and adjusting that copy's minimum/maximum value for
scaling into the target normalized range.
The 1%/5% tip thresholds are kept but pressure offset detection is
disabled if there is a custom pressure range.
Unlike the pressure curve which is implemented in the compositor, the
pressure min/max range needs to be in libinput, primarily because the
tip threshold needs to adjust to any new minimum, allowing for
light touches with a pen without triggering tip down even at a higher
hardware pressure.
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.

Add option to control whether the touchpad should be disabled while the
trackpoint is in use.
