The i2c one came from an Dell XPS13. The ALPS one I can't remember but highly
likely they were on Dells and if not, nothing really changes here anyway
because it's not a clickpad and right now only clickpads have dell-specific
behaviour.

We simply don't have enough space on those touchpads to have an area carved
out for horizontal scrolling. Given that horizontal scrolling is rarely needed
anyway users of these touchpads will just have to cling to scroll bars or use
two-finger scrolling.
Exception are small clickpads because they already have an area blocked off
for software buttons and those small clickpads generally come from a time when
clickfinger wasn't much of a thing yet.

10s is not enough when running the test suite in parallel as any test may have

litest_add_device and litest_delete_device trigger a udev rule reload. This

To unify this we need to move the tagging process forward so tp_init() can
rely on it for config setup. This means moving it to the touchpad init code.
Other than that no real functional changes, the rules stay the same:
* serial/i2c/etc. are considered internal touchpads
* Bluetooth is always external
* USB is external for Logitech devices
* USB is external for Wacom devices
* USB is internal for Apple touchpads
And if we can't figure it out, we assume it's external and log a message so we
can put a quirk in place.

Increase the mm move threshold for 3 and 4 finger gestures to 2 and 3 mm,
respectively. In multi-finger gestures it's common to have minor movement
while all fingers are being put down or before the conscious movement starts.
This can trigger invalid gesture detection (e.g. a pinch instead of a swipe).
Increase the movement threshold to make sure we have sufficient input data.
No changes to 2-finger movements.

A natural hand position for a 4-finger swipe will have one finger well below
the other triggering the pinch detection. This is obviously wrong, only do the
finger position analysis when we have 2 fingers.
This is only a partial fix, for 3-4 finger gestures chances are high that the
third/fourth finger come in a different event frame. Before that we likely
detect 2 fingers in a possible pinch position and still trigger the code path.
This issue has to be fixed separately.

The current code tried to emulate the relative motion to be equivalent to the
absolute motion, except in screen coordinates. This is way too slow for the
cursor tool that we want to behave like a mouse.
Tablets have high resolution (e.g. an Intuos 4 is a 5080dpi mouse) and that
motion is way too fast to be usable. Scale it down to match a 1000dpi device
instead. Since the cursor and lens tool are still high precision devices leave
them in a flat acceleration profile without actual acceleration.
For the stylus-like devices leave the current accel, pointer acceleration on a
stylus is hard to handle.
This also adds the missing bits for actually using the speed factor set
through the config interface.
