This test was putting both fingers down in the thumb area. That's not
representative, it's more likely that a thumb is in the area and the second
finger clicks elsewhere. So let's test for that instead.

These were supposed to test the thumb area, but the pressure exceeded the
threshold for most devices, thus ending up testing the palm detection instead.
Fix to use a timeout where possible, otherwise move them to the palm detection
code instead.

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.

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

__builtin_popcount might not be available and in this case, a bitwise-and
can accomplish the same task.
Signed-off-by: Michael Forney <mforney@mforney.org>
__builtin_popcount might not be available on all compilers, so using
it requires a configure check and fallback implementation. In fact
on gcc without an -march flag, it gets compiled to a function call to
libgcc. However, we only need to test whether multiple bits are set,
and this can be done easily with a bitwise and.

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.

If we don't handle a device, don't touch it. Especially joysticks that we
don't handle and thus should not touch either.

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.

This is the public API only, not the internal bits, so nothing will work just
yet.
This interface addition is for the Dell Canvas Totem tool, so let's go with
the same name because options like "Rotary" are too ambiguous.
The totem is a knob that can be placed on the surface, it provides us with
location and rotation data. The touch major/minor fields are filled in by the
current totem, but they're always the same size.
The totem exports BTN_0 as well, so let's add that to the debug-events output.

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.

No real changes for the non-tablet code, but for tablets we now keep the
libwacom datbase around. The primary motivating factor here is response time
during tests - initializing the database under valgrind took longer than the
proximity timeouts and caused random test case failures when a proximity out
was triggered before we even got to process the first event.
This is unfortunately a burden on the runtime now since we keep libwacom
around whenever a tablet is connected. Not much of an impact though, I
suspect, chances are you're running a web browser and everything pales against
that anyway.
