Some trackpoints, notably the one on the Lenovo T460s have a tendency to send
the odd event even when they're not actually used. Trackpoint events trigger
palm detection (see 0210f1fee1) and thus effectively disable the touchpad,
causing the touchpad to appear nonresponsive.
Fix this by requiring at least 3 events from a trackpoint before palm
detection is enabled. For normal use it's hard enough to trigger a single
event anyway so this should not affect the normal use-case.

(cherry picked from commit 18adfed4c1)
If a tool starts reporting with serial 0 and later updates to a real serial,
discard that serial and keep reporting as serial 0. We cannot really change
the tool after proximity in as we don't know when callers query for the serial
(well, we could know but any well-written caller will ask for the serial on
the proximity in event, so what's the point).
Thus if we do get a serial in and the matching tool, check if we have a tool
with the serial 0 already. If so, re-use that. This means we lose correct tool
tracking on such tablets but so far these seem to only be on devices where the
use of multiple tools is unlikely.

(cherry picked from commit 64c8939911)
We've already been doing this for semi-mt devices and for non-clickpads but
let's do it for clickpads as well. On Synaptics touchpads (PS/2 and RMI4)
we see slot jumps where two slots are active, slot X ends but slot Y continues
with the other slot's positional data. This causes a cursor jump on finger
lift after a two-finger scrolling motion. Simply resetting the motion history fixes it.
The only multi-finger interaction where a user could expect perfect fluid
motion is when using a second finger to touch cone of the software button
areas. Let's see if we have complaints first before we implement something
more complex.

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.

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.
