This was a bad idea. No-one seems to use this and it gives us little benefits.
To even get this feature a number of other features need to be turned off
(like two-finger scrolling and tapping). Many of these are enabled by default,
if they are disabled a client stack with full touchpad gesture support could
in theory support true touchpad gestures. This has never happened.
Drop the touch events from the synaptics driver. This allows us to switch the
touchpad fully over to look like a relative device, thus also removing the
bug that changes the touchpad speed whenever a monitor is added/removed in.

This reverts commit 064445364b4775b25ba49c2250b22b169f291147.
The Lenovo *50 series, including the X1 Carbon 3rd always require multiple
kernel patches to enable the touchpad buttons. This patch in synaptics only
addresses the re-routing of the top buttons.
The final iteration of the kernel patches also route the trackpoint buttons
through the trackpoint device, rendering this patch unnecessary. These patches
are queued for 4.0.

Some applications ignore the second tap of double taps because of the
lack of a delay between the button down and button up events.
Prevent this by replacing the transition from TS_2B to TS_START with a
transition from TS_2B to TS_SINGLETAP that emits only a button down
event. The button up event will be emitted when transitioning from
TS_SINGLETAP to TS_START.
In addition, decrease the default value of MaxDoubleTapTime from 180 ms
to 100 ms in order to make double taps faster.

This device has the trackpoint buttons wired up to the touchpad to send BTN_0,
BTN_1 and BTN_2 for left, right, middle. This conflicts with previous
touchpads that used those event codes for dedicated scroll buttons.
Add an option HasTrackpointButtons that can be set via a xorg.conf.d
snippets. This option is not intended as a user-set option, rather
we expect distributions to ship some conglomerate of udev/hal rules with
xorg.conf snippets that take effect.
If the option is set, we look at the three affected buttons at the beginning
of HandleState and send button events immediately for them. The HW state is
reset to neutral and other processing continues. This saves us from having to
synchronize these buttons with software buttons (also present on this device),
tapping, etc.
Since the buttons are physically different and (mentally) associated with the
trackpoint device we also don't need to worry about having finger motion event
correctly synced up with the button presses - it's acceptable to send the
presses before the motion events.

The palm detection relies on both the width and the pressure.
a897147be04 ("Use ABS_MT events for the palm detection when supported")
assumed that all the touch devices can report both ABS_MT_TOUCH_MAJOR
and ABS_MT_PRESSURE, but this is not necessarily true. This assumption
could hence break the palm detection when at least one of the mentioned
events is not declared but both ABS_TOOL_WIDTH and ABS_PRESSURE are
reported.

Use ABS_MT_TOUCH_MAJOR and ABS_MT_PRESSURE instead of ABS_TOOL_WIDTH
and ABS_PRESSURE when supported so that the pressure and the width of
all the fingers is taken into account for the palm detection.
This also fixes the palm detection for those touchpads for which the
kernel only sends ABS_MT_TOUCH_MAJOR and not ABS_TOOL_WIDTH.

Touchpads are limited by a fixed sampling rate (usually 80Hz). Some finger
changes may happen too fast for this sampling rate, resulting in two distinct
event sequences:
* finger 1 up and finger 2 down in the same EV_SYN frame. Synaptics sees one
finger down before and after and the changed coordinates
* finger 1 up and finger 2 down _between_ two EV_SYN frames. Synaptics sees one
touchpoint move from f1 position to f2 position.
That move causes a large cursor jump. The former could be solved (with
difficulty) by adding fake EV_SYN handling after releasing touchpoints but
that won't fix the latter case.
So as a solution for now limit the finger movement to 20mm per event.
Tests on a T440 and an x220 showed that this is just above what a reasonable
finger movement would trigger. If a movement is greater than that limit, reset
it to 0/0.
On devices without resolution, use 0.25 of the touchpad's diagonal instead.

Default on evdev devices is CLOCK_REALTIME. If that clock falls behind the
server's CLOCK_MONOTONIC, motion after a clickpad click may be delayed by the
difference in the clocks.
In detail:
When the timer func is triggered, GetTimeInMillis() which is CLOCK_MONOTONIC,
is stored as hwState->millis. The eventcomm backend uses struct
input_event time (CLOCK_REALTIME).
When we read events from the device, if the evdev time is less than the server
time, the fix for (#48777) sets the current event time to hwState->millis.
Until the evdev time overtakes that stored time, all events have the
hwState->millis time.
If during that time a clickpad triggers a physical click,
clickpad_click_millis is set to hwState->millis + the ignore-motion timeout.
Thus, all motion is ignored until the event time overtakes that stored
time.
The whole issue is further enhanced by us unconditionally setting the timer
func if we get any events, which is a separate issue anyway.

When two fingers are used, the coordinates of only one of them is taken into
account. This can lead to sudden variations of the absolute coordinates when
two-fingers taps are performed if the finger considered changes.
Take into account coordinates variations to prevent unwanted taps only if
the number of fingers doesn't change.

We had reports that the top software button area is hard to hit for those
using the trackpoint and clicking the buttons with their thumb.
Analysis of event recordings (3 different people) for left, right and middle
clicks shows that there is a significant amount of events up to about 10mm
(with outliers up to 12mm) from the top of the touchpad. That maps to 15%.
Interestingly, the middle button does not seem to need this, presumably the
haptic feedback of the little dots sticking out from the surface make hitting
the button easier. Its size is increased to 15% anyway, for simplicity and
because a sample set of 3 is too small to be definitive about this.

When we required a grab on the device, this was a shortcut so we didn't have
to query the device only to realise we can't read events off it anyway. Now
that we don't actually grab the device by default, this is unnecessary.
Something else may have a temporary grab on the device during init, in which
case we just continue as usual and read events if and when they become
available.

Add a HasSecondaryButtons boolean config option which defaults to true for
devices with the INPUT_PROP_TOPBUTTONPAD and false for all other devices.
Only parse the SecondarySoftButtonAreas when this option is true, effectively
disabling the top buttons when it is false. Likewise, only initialize the
SecondarySoftButtonAreas property if we enable support for it.
This means that it is now safe to always set a SecondarySoftButtonAreas
default in 50-synaptics.conf, and that he section which was intended for
use with future pnp-id matching can be dropped, as that is now all handled
in the kernel.
While at also remove the comment about disabling the bottom edge area, as that
is now done automatically.

When trying to do a 3 fingerclick on a touchpad which only tracks 2 touches,
this may register as a 3 or 2 fingerclick depending on the order in which
the touchpad detects the fingers. If the 2 outer fingers of the 3 get seen
first, then the 2 touches will be too far apart for the heuristic to see
them as being close together, and the click gets counted as a 2 finger click.
A user will likely never do a 2 finger click with a 3th finger resting
somewhere else on the pad, where-as the above misdetection of the clicks is
a real issue, so simply always count a click with trippletap set as a
3 finger click on pads which track less then 3 touches.

This is a bit problematic: libevdev only has one global log handler.
So if we have another driver use libevdev, we'll either overwrite that handler
or get overwritten, whichever comes first. So we need to re-set the handler
every time we get an event to make sure we log through our handler.
Likewise, if we ever drop the device, we need to unset the log handler back to
NULL because we may unload the module and our handler may disappear.
Use the lowest logging priority, let the server filter based on the verbosity
level instead.

of a bug is significant.
Check the configuration source on init. If the device was hotplugged through a

configured through an xorg.conf then leave the default grab enabled to avoid

Enabling clicks in off mode also allows for the new Lenovo *40 series to use
the top software buttons while the touchpad is disabled. This benefits those
that usually disable touchpads altogether but still need the buttons for the
trackstick.
This changes existing behaviour, but TouchpadOff was always intended to stop
erroneous events while typing. Physical button presses are hard to trigger
accidentally. On the touchpads that TouchpadOff concept was originally
designed for the buttons are nowhere near the keyboard and are physically
separated from the touchpad anyway. On Clickpads, triggering a physical
click requires more force than accidentally touching the surface.
