This commit changes two things with the way distance and pressure axes are
reported:
1. Distance and pressure are made mutually exclusive. When there is a distance
event and a pressure event and the tool is in contact with the tablet, only
the pressure change will be reported. When the tool is not in contact and
both a distance and pressure change are received, only the distance update
will be received.
2. Bad distance events are not reported to the caller. There is a certain
distance a tool can be from the tablet where the tablet recongnizes that a
tool appeared, but the tool doesn't send any useful information to the
tablet. When this happens, the distance will update to it's minimum or
maximum value, and no other axis updates will be sent. Since this can give
a caller the impression that the tool is within a useful proximity of the
tablet, we filter out any distance events with a value of maximum or minimum
when the tool is not within useful proximity of the tablet.

Report the values for the distance, pressure, and tilt axes. Pressure is
normalized to a range of 0 to 1, and tilt is normalized to a range of -1 to 1.

This event is just used to notify the caller when the tool's no longer in
proximity. When an event like this occurs, everything from evdev up until the
next EV_SYN event is discarded along with any events that occured since the last
EV_SYN event. This also silences any tool update events where the tool type is
changed to LIBINPUT_TOOL_NONE, so we don't end up filling the tool list with a
bunch of tools that aren't actually tools.

These devices set the LIBINPUT_DEVICE_CAP_TABLET flag, and emit a lot more axis
information then mice and touchpads. As such, tablet events are in a whole new
group of events that is separate from everything else.
In this commit, only X and Y axes are reported in libinput.
