This test is supposed to test for the timeout kicking in on edge scrolling -
if the finger is in the edge for longer than the timeout, we switch to
scrolling without requiring the motion threshold to be met first.
To emulate this, move the finger ever so slightly first to load up the motion
history, then timeout, then move. We expect a bunch of motion events with a
small delta.

The first finger is accurate, it's just the second finger that is imprecise,
so we can't handle it as a true touch. Instead, revert the device back to
being a single-touch touchpad and use the fake touch bits for second finger
handling.
Two-finger scrolling thus becomes usable though we will lose out on
other features like thumb detection. Useful scrolling trumps that though.

Add a LIBINPUT_TEST_DEVICE udev parameter to test devices created by
the test suite. When an application tries to add such a device to the
path backend or when the udev backend discovers such a device, it will
be ignored. Only the context when run via the test suite will actually
handle these devices.
Doing this will enable a user to run the libinput test suite on a system
running libinput without having the test suite devices interfering with
the actual system.
Note that X.org users running an input device driver that is not the
libinput X input driver will still need to manually configure the X
server to ignore such devices (see test/50-litest.conf).

We currently rely on an extra millisecond being added by the filter
code to get a velocity that are small enough to not hit the max
acceleration limit. If this arbitrary millisecond is changed (for
example by changing the internal time measurment to microseconds and
adding just a microsecond instead), the velocity may change so that the
maximum or minimum acceleration is always hit.
Adding a delay to the test won't work either since it would not only rely
on ending up within the acceleration limits but there would also be an
non-deterministic actual delay causing the velocity of the movement
after the direction change to be potentially larger than the movement
in the original direction due to the actual time delta in libinput will
not always be 1ms.
To fix the test to not rely on any artificial delays in the filter code
nor any non-deterministic delays in the test, lets just test that the
direction change of the hardware events resulted in a direction change
of the libinput motion events.

It's reasonable to expect a thumb (or the other hand's index finger) to click
a button while a finger is down for movement. It's less reasonable to expect
this when two fingers are interacting with the touchpad, or when two fingers
click the touchpad (even on a large touchpad that's an awkward position).
Simplify the clickfinger detection mechanism - if we have three touches down,
it's always a three-finger click. Two fingers may be a right click or a index
+ thumb click.

That's the most likely area it will be resting in, if it's sitting anywhere
above that it's likely part of an interaction.
A thumb in the lowest 15mm needs to trigger the pressure threshold before it's
labelled a thumb. A thumb in the lowest 8mm is considered a thumb if it
remains there for 300ms. Regardless of the pressure, since we can't reliably
get pressure here. If a thumb moves out of the area, or starts outside of that
area it is never a thumb.
If edge scrolling is enabled, the 8mm threshold is ineffective since we'll
have normal interaction in that zone for horizontal scrolling.
The thumb tests now require all touchpads to be switched to clickfinger, if we
test for thumb detection on the bottom of the pad we won't get expected
motion events due to the software button area.

Synatics touchpads only have 2 slots, but support TRIPLETAP and above. When
the third finger touches, the kernel may end the second slot and re-start it
with the coordinates of the third touch in the next frame. The event sequence
is something like:
ABS_MT_SLOT 0
ABS_MT_POSITION_X 4000
ABS_MT_POSITION_Y 4000
ABS_MT_PRESSURE 78
ABS_MT_SLOT 1
ABS_MT_TRACKING_ID -1
ABS_X 4000
ABS_Y 4000
ABS_PRESSURE 78
BTN_TOOL_DOUBLETAP 0
BTN_TOOL_TRIPLETAP 1
--- SYN_REPORT (0) ----------
ABS_MT_SLOT 0
ABS_MT_POSITION_X 4000
ABS_MT_POSITION_Y 4000
ABS_MT_PRESSURE 78
ABS_MT_SLOT 1
ABS_MT_TRACKING_ID 55
ABS_MT_POSITION_X 2000
ABS_MT_POSITION_Y 2000
ABS_MT_PRESSURE 72
ABS_X 4000
ABS_Y 4000
ABS_PRESSURE 78
--- SYN_REPORT (0) ----------
libinput usually ignores any BTN_TOOL_* <= num_slots since we expect
that the slot values are valid. Make an exception for the serial synaptics
touchpads. If a touch has ended when the fake touch goes above active-slots
(but still within num-slots), move that touch back to UPDATE. This ensures the
right number of nfingers_down. When the touch restarts again in the next
frame, tp_begin_touch() will skip over re-initializing it because it's already
in UPDATE anyway.
Note that at this point this only handles the transition _to_ TRIPLETAP, not
from TRIPLETAP to DOUBLETAP. Need to wait for this to be seen in the wild
first.

The average human hand has four fingers but only one thumb, i.e. the chance of
a fake finger being close to the top-most touch is higher than to whatever the
first touch was (which may be a thumb at the bottom of the touchpad).
So search for the top-most real touch and copy its position into the fake
touches.
This also fixes another bug with the previous code - the first slot may not be
active but we still used its position for the fake touches. Whether that was
really triggerable is questionable though.
The test is only run for the T440 touchpad - we know it's big enough to
enable thumb detection and that way we don't have to double-check in the how
big the touchpad is, etc.
