litest_wait_for_event_of_type() skips all other events in the queue before the
one we want. This isn't appropriate in most cases, and unless we're dealing
with timeouts we should assume that a certain sequence triggered a specific
event rather than waiting some time for it to trigger.

Print the type of event when it is queued up internally. This makes it a lot
easier to associate evdev events with the libinput event queued up and does
not depend on the caller calling libinput_dispatch().
Since this should only be used during development, hide it behind an if 0.

For the puck/lens cursor tool we need to artificially reduce proximity
detection. These tools are usually used in a relative mode (i.e. like a mouse)
and thus require lifting and resetting the tool multiple times to move across
the screen. The tablets' distance detection goes too far, requiring the user
to lift the device several cm on every move. This is uncomfortable.
Introduce an artificial distance threshold for the devices with the default
value taken from the X.Org wacom driver. If a tool is in proximity but outside
of this range, fake proximity events accordingly.
If a button was pressed while we were out of range we discard that event and
send it later when we enter proximity again.
This is the simple implementation that only takes one proximity out value (the
one from the wacom driver) and applies it to all. Those devices that support a
button/lens tool and have a different default threshold are well out of date.

For checking if a tablet tool can be uniquely identified by libinput. In
practice this means checking for a nonzero serial number, but let's not

The only time we need this is on proximity in, so move it to where we handle
that to have better locality. And rather than looping through and checking
each bit, just memcpy the axis capabilities, because by definition they
represent the set of axes that can possibly change.

Process the axes explicitly, rather than having a loop that needs special
casing for most axes anyway. And since we do the axes one-by-one, we can use
the evdev axis code directly rather than the axis_to_evcode helper.

Only the rel wheel has true delta events, everything else is a delta
calculated by libinput based on the previous position. Since we supply that
position to the callers anyway, they can determine that delta themselves

Part of the big revamp to get rid of libinput_tablet_tool_axis and

Note that this commit drops the ability to check whether a tablet has an x or
y axis. If it doesn't, libinput won't initialize the tablet anyway so this was
superfluous already.
Likewise with the tilt axes - either we have x and y tilt or we have neither,
so separate checks for tilt_x and tilt_y is unnecessary.

If a tool wears out, it may have a pre-loaded pressure offset. In that case,
even when the tool is not physically in contact with the tablet surface it
will send pressure events.
Use automatic pressure offset detection, similar to what the X.Org wacom
driver does. On proximity-in, check the pressure and if the distance is above
50% of the range and the pressure is nonzero but below 20% of the range, use
that value as pressure offset.
