We used to mark dell touchpads this way but let's make this more generic.
Nothing else used the dell touchpad model flag, so we can simply replace it.

If the fingers rest on the touchpad without moving for a timeout, switch to
pinch or swipe based on the finger position. We already switched to two-finger
scrolling based on the timeout, now we also do so for 3 and 4 finger gestures.
This gives us better reaction to small movements.
This also fixes previously unreachable code: the test for the finger position
required at least 3 fingers down but was within a condition that ensured only
2 fingers were down. This was introduced in 11917061fe.

(cherry picked from commit 5307051386)
The Elantech touchpad on my Asus Vivobook doesn't release BTN_TOOL_FINGER on
up. If the touchpad was used before libinput initializes, the kernel filters
the event because its state is already set. We never receive it and keep
ignoring all events until the first switch to BTN_TOOL_DOUBLETAP and back.
On touchpad init sync the BTN_TOOL_FINGER state and set it accordingly. This
is the only event that can be legitimately down on init. We don't care about
BTN_TOUCH because ignoring an ongoing touch on init is generally a good idea
and we can ignore any multifinger gesture as well.

This touchpad has cursor jumps for 2-finger scrolling that also affects the
single-finger emulation. So disable any multitouch bits on this device and
disallow the 2-finger scroll method. This still allows for 2-finger
tapping/clicking.

Taking the last 4 points means factoring in a coordinate that may be more than
40ms in the past - or even more when the finger moves slowly and we don't get
events for a while. This makes the pointer more sluggish and slower to catch up
with what the finger is actually doing.
We already have the motion hysteresis as a separate item to prevent jumps (and
thus adds some delay to the movement), the calculation over time doesn't
provide enough benefit to justify the sluggish pointer.

The hysteresis cuts the first pointer motion by the hysteresis margin. On some
touchpads this causes the tests to fail when the motion history length is
reduced (future patch). Allow the first event to be smaller than the expected
minimum.
This doesn't trigger in current tests because the hysteresis is per-event and
by the time we get past the minimum 4 events to move the pointer, we're
already flying unaffected by the hysteresis.

The test is supposed to make sure no motion event is sent and that scrolling
continues once leaving the edge. It does so by moving down the edge, into the
touchpad, then down further. The move from the edge into the touchpad had a
vertical component to it though and could cause the scroll minimum test to
fail. This is currently covered up by the delta calculations though, but fix
it anyway.

This doesn't have an effect in our current tests because the touchpad always
needs 4 motion events to get moving. But for the future, it simplifies the
case of "i want to move between x1/y1 and x2/y2", because it fills in only the
events in between rather than re-using the touch down coordinates and thus not
causing a motion on the first event.
