This pen has random timeouts, often when a button is pressed. This causes a
forced proximity out (and the button release) and makes the whole device a
tad unusable.
Nothing we can detect by heuristics since it looks like other devices that
don't send proximity out events. And the timeout can be quite high, the
recording in #304 has over 800ms for one sequence.
Fixes#304

Where the proximity out event is delayed by the kernel, libinput would cause
an extra proxmity in-out after the forced proximity out event.
Event sequence is basically (k: kernel, l: libinput)
k: tablet axis events
l: tablet axis events
k: nothing for $proximity timer milliseconds
l: tablet proximity out
k: proximity out event
l: proximity in event
l: proximity out event

We only ever set properties in the devices, so let's make that more explicit
and auto-generate the udev rule. This way we're hopefully better protected
from the various typos that hid in those rules over the years, but also be
prepared for passing the udev property key/value pairs elsewhere.

This escaped us before because the MOUSE_DPI setting on the low-dpi device was

The touchpad_2fg_scroll_initially_diagonal test would semi-reliably fail under
valgrind but succeed otherwise. Cause was that on some devices, the initial
diagonal movement wasn't diagonal enough and closer to a horizontal movement.
This was fine on normal runs, but under valgrind we'd hit the "active
threshold" time limit and lock to horizontal scrolling, ditching the remaining
events and failing the test.
Fix this by calculating the scroll vector based on the device's width/height
ratio and go "more diagonal" on the initial vector.

This device looks similar to a MT device on the kernel side, but it's not a
MT device and it's not quite a tablet either. It uses slots to track up to 4
totems off the same device and the only hint that it's not a MT device is that
it sends ABS_MT_TOOL_TYPE / MT_TOOL_DIAL.
udev thinks it's a touchscreen and a tablet but we currently init those
devices as touchscreen (because all wacom tablet touch devices are udev
tablets+tochscreens). So we need a quirk to hook onto this device.
And we use a completely separate dispatch implementation, because adding the
behavior to the tablet interface requires so many exceptions that it's easier
to just add a separate dispatch interface.

Some versions [1] of the Lenovo ThinkPad Compact USB Keyboard with TrackPoint USB
have the pointing stick on an event node that has keys but is not a regular
keyboard. Thus the stick falls through the cracks and gets disabled on tablet
mode switch. Instead of adding more hacks let's do this properly: tag the
pointing stick as external and have the code in place to deal with that.

WEXITSTATUS() "should be employed only if WIFEXITED returned true", see
wait(2). If a test failed with an abort, WIFEXITED is false and WEXITSTATUS
is... undefined? and apparently zero, so test case failures would cause a
false postive test result.
This doesn't affect a normal test run because check handles the aborts
correctly, but the valgrind invocation with CK_FORK ended up being handle by
litest. So with the result that any abort during valgrind was a silent success
and if there was a memleak in the same process that exited with a signal, the
memleak would be ignored too.

Tablets in left-handed mode are rotated, so we need to rotate the touchpad
part of them too. This doesn't affect all tablets though, some of them are
symmetrical and the left-handed mode merely changes the button order around
(some of the earlier Bamboos). So we rely on libwacom to tell us which device
must be rotated.
The rotation itself is done on the input coordinate itself as we get it. This
way any software buttons, palm zones, etc. are automatically handled by rest
of the code.

Unlike virtually everything else, the tablet tool was processed at the time
the event was read rather than when the subsequent EV_SYN came in. This causes
difficulties with tablets that send the wrong BTN_TOOL_PEN events.
Moving the tool change processing to tablet_flush() makes the injection of the
BTN_TOOL_PEN event a lot easier, simply flipping the matching bit does the
job. It also makes it easier to ignore duplicate tool updates like we've seen
in #259.

Don't require a quirk update, just enable this by default for all tablets. If
we get a proximity out event at the right time, the quirk is disabled for that

trigger events for 50ms.

it obvious.

accordingly but that requires more effort.
