6d435cda06 gestures: don't try to pinch for nfingers > slots
We don't know the position of the third finger on 2-slot touchpads, differing
between swipe and pinch is reliable. Simply disable 3-finger pinch and always
use swipe; 3fg pinch is uncommon anyway and it's better to have one of the
gestures working reliably than both unreliably.

6bb05c594a lid: disable all types but EV_SYN and EV_SW
The lid dispatch interface is a one-trick pony and can only handle SW_LID. It
ignores other switches but crashes on any event type other than EV_SW and
EV_SYN. Disable those types so we just ignore the event instead of asserting.

55d1bb1217 pointer: add button debouncing
Some devices have worn-out switches or just cheap switches that trigger
multiple button events for each press. These can be identified by unfeasably
short time deltas between the release and the next press event. In the
recordings I've seen so far, that timeout is 8ms.

We have a two-stage behavior: by default, we do not delay any events but we
monitor timestamps. The first time a bouncing button is detected we switch to
debounce mode. From then on, release events are delayed slightly to check for
subsequent button events. If one occurs, the releas and press are filtered. If
none occurs, the release event is passed to the caller.

6d0edf9d07 timer: always restart the timer loop when we called one of them
If a timer_func causes the removal or addition of a different timer, our tmp
pointer from the list_for_each_safe may not be valid anymore.

This was triggered by having the debounce code trigger a middle button state
change, which caused that timer to be cancelled.

696fdff247 timer: if a timer is inactive, do not call the timer func
Race conditions may happen where code that cancels a timer is called just
as that timer triggers. If we cancel a timer, we assume that we've put the
code into a state where the timer firing will trigger a bug.

This could be observed with the middle button code if the release event was
held back just long enough. The button release code cancelled the timer, set
the state back to idle and then complained when the timeout handling sent a
'timeout' event while being in idle.

399c50dbeb evdev: recover from a lost button count
If the kernel sends us a button press for a button that is thought to be down
we have lost track of the state of the button. Ignore the button press event,
in the hope that the next release makes things right again.

A release event may be masked if another process grabs the device for some
period of time, e.g. libinput debug-events --grab.

3669fa10df trackpoint: drop handling of CONST_ACCEL and undo SENSITIVITY
This was to counteract hardware that doesn't work well out of the box,
resulting in quite different behavior across devices. Specifically, only
some trackpoints even have the sensitivity setting.

Change to take over all of the pointer acceleration on trackpoints, so we can
control the actual behavior mostly independent of the system setting. So we
drop the CONST_ACCEL parsing (which never was handled as const accel anyway)
and undo the effect that the SENSITIVITY udev property has. [1]

We take a default range at the default sensitivity and multiply it by the
proportion of the current sensitivity. This seems to be accurate enough.

[1] In the future, we should read not only the property but also the sysfs file to
make sure we're handling the right value, but for now this will do.

432fbc33cd touchpad: add touch-size based touch handling
Apple touchpads don't use ABS_MT_PRESSURE but they are multitouch touchpads,
so the current pressure-based handling code doesn't apply because it expects
slot-based pressure for mt touchpads.

Apple does however send useful data for ABS_MT_WIDTH_MAJOR/MINOR, so let's use
that instead. The data provided in those is more-or-less random, so we need a
hwdb entry to track the acceptable thresholds.

eb36957625 Add support for CircleCI
This isn't currently hooked up to the fdo repo but it's hooked up to my
github mirror. I had SemaphoreCI hooked up to that before but it only
supports ubuntu 14.04 and the recent meson switch made it a bit hard to setup.

CircleCI supports running docker containers, so let's do that and run against
the most recent released Fedora and a recent Ubuntu. I'm not bothering with
rawhide, it's likely to increase the work for little gain when it's in a
semi-broken state.

Run the default build with a few permutations to test meson options. Run
scan-build too but that's just for the logs, eventually this may turn into a
hard failure.

Ubuntu 17.04's meson is too old, so we have to clone that from git. Install
arguments are taken from the meson.deb package.

Most of this effort was done by Benjamin Tissoires.

6a77cae850 touchpad: sync the slot state after tp_resume()
If the touchpad is suspended and resumed (e.g. lid switch), the initial slot
state may be out of sync. If a touch happened while the touchpad was suspended
and the next touch down is on exactly the same x and/or y coordinate, our
touch point would still have the coordinates of the most recently seen touch
(i.e. before touchpad suspend). This could cause a pointer jump or test case
failures.

The real-world impact of this is minimal, putting the finger down in exactly
the same spot is virtually impossible. It could cause a test case failure in the
lid_disable_touchpad() test though, the second touch sequence was on the same
y coordinate and the touch location for that whole sequence was x/0.

a31e4b818c test: remove failing thumb edge scroll test
Broken since the merge of palm pressure detection in
25d54b90d, not sure why the test suite succeeded on that one nonetheless.

I'm not 100% sure why the test does what it does but it seems to be testing
that a wide touch on the side still striggers edge scrolling and not the thumb
detection on the bottom of the touchpad. That is obsolete now, it's hard to
generically figure out the small gap between thumb and palm pressure, so this
test almost always triggers palm detection. It's obsolete.

d698de6e68 touchpad: send a left button event when we move out of topbuttons and click
We used to completely ignore a finger that was within the top software button
area and then moved to the main area and remained there for a timeout. This
avoids erroneous pointer movements when the user moves the finger while using
the trackpoint.

But we also ignored physical clicks, something we should not be doing. This
patch fixes that behavior: we still ignore the finger for movement, but a
physical click now triggers a left click once we've been in the area for the
timeout.

This new behavior doesn't apply within the timeout, i.e. if a finger is in the
right top button area, moves out and immediately clicks, we still trigger a
right click. This avoids erroneous switches to left-clicks when the finger is
at the edge of the button area and moves out during the press.
