6cdf46f857 plugins: restore the wheel plugin specifically for the MX Master 3
The MX Master 3 is difficult, its wheel events are all over the place
and heuristics are tricky to determine. The previous plugin behavior
was seemingly sufficient for the MX Master but not for other devices.

Restore the old behavior if the quirk is set for a device by adding a
fourth state ALWAYS_ACCUMULATE. In this state the min movement is never
updated from the original threshold, causing any wheel motion to
accumulate.

Ref: ca6b82841c ("plugin/wheel: tighten the wheel debouncing code")
Ref: bb05e0d1b5 ("plugin/wheel: don't accumulate for low HID resolution multipliers")

efb4b6a3be evdev: detect virtual devices
The quirk AttrIsVirtual takes precedence, if present. If not, use the
syspath of the event device to detect if it is virtual, as long as we
aren't running the test suite. (Test suite devices are all virtual, but
we should test them as if they aren't.)

76c87d2486 util: add various helper functions to use __attribute__(cleanup)
Taken from libei, with slight modifications. The general approach is:
basic data types use _autofoo_ to call the maching foo function on
cleanup. Struct types use _unref_, _destory_, _free_, whichever applies
to that struct.

Notably: attribute syntax depends on where it's declared [1] so in the
following examles only a, b, and d have the autofree attribute:
   _autofree_ char *a, *b;
   char *c, _autofree *d;

Simplest way to ensure it's all correct to keep the declarations one per
line.

Unlike in traditional touchpads, whose pressure value equals contact
size, on pressure pads pressure is a real physical axis.

a7e4cbc212 quirks: allow overriding of AttrEventCode and AttrInputProp
This switches the quirk from AttrEventCodeEnable/Disable to just
AttrEventCode with a +/- prefix for each entry.
This switches the quirk from AttrInputPropEnable/Disable to just
AttrInputProp with a +/- prefix for each entry.

Previously, both event codes and input props would only apply the
last-matching section entry for a device. Furthermore, an earlier Disable entry
would take precedence over a later Enable entry. For example, a set of
sections with these lines *should* enable left, right and middle:

  [first]
  AttrEventCodeEnable=BTN_LEFT;BTN_RIGHT;BTN_MIDDLE

  [second]
  AttrEventCodeDisable=BTN_RIGHT

  [third]
  AttrEventCodeEnable=BTN_LEFT;BTN_RIGHT;

Alas: the first line was effectively ignored (quirks only returned the
last-matching one, i.e. the one from "third"). And due to implementation
details in evdev.c, the Disable attribute was processed after Enable,
i.e. the device was enabled for left + right and then disabled for
right. As a result, the device only had BTN_LEFT enabled.

Fix this by changing the attribute to carry both enable/disable
information and merging the commands together.

Internally, all quirks matching a device are simply ref'd into an array
in the struct quirks. The applied value is simply the last entry in the
array corresponding to our quirk.

For AttrEventCode and AttrInputProp instead do this:
- switch them to a tuple with the code as first entry and a boolean
  enable/disable as second entry
- if the struct quirk already has an entry for either, append the more
  recent one to the existing entry (instead of creating a new entry in
  the array). This way we have all entries that match and in-order of
  precedence - i.e. we can process them left-to-right to end up
  with the right state.

ac91d8df3b touchpad: disable jump detection on the Lenovo X1 Gen6 touchpad
This touchpad has firmware that seems to buffer events. In the words of the
reporter:

  In usage, it feels like motions vary between smooth and choppy; slow
  movements are smooth and quick movements are choppy. It's as if the
  touchpad aggregates quick movements and sends one big movement instead
  of sending discrete events. To make the movement more natural, the
  events preceding the jump should be of higher magnitude and the jump
  less pronounced, but that's just not how the touchpad works, it seems.

In the actual event data this looks exactly like a pointer jump: small
movements, one big one, then small ones again. If we filter that large
movement out we prevent the user from moving quickly.

There's no way to detect this or work around this, so let's add a quirk that
disables the jump detection for this device.

c457050d44 Revert "tablet: don't disable the proximity quirk on good sequences"
This quirk was introduced for #248 was caused by buggy input-wacom drivers,
not by actual firmware, see
https://gitlab.freedesktop.org/libinput/libinput/issues/381#note_279371

This appears to be the only tablet where this fix was needed, but we've been
playing whack-a-mole ever since to work around the various other tablets that
break with this behavior in place.

So let's revert that fix and hope there aren't any other tablets out there
(and if they are, we can probably quirk those). The revert makes the ISDV4 pen
quirk obsolete (see 9cb089f2b6), so this was
folded into this commit.

This reverts commit 4f63345b60.

9cb089f2b6 tablet: disable the forced proximity out for the Dell Canvas pen
This pen has random timeouts, often when a button is pressed. This causes a
forced proximity out (and the button release) and makes the whole device a
tad unusable.

Nothing we can detect by heuristics since it looks like other devices that
don't send proximity out events. And the timeout can be quite high, the
recording in #304 has over 800ms for one sequence.

bf4277623f Add a new dispatch interface for the Dell Canvas Totem
This device looks similar to a MT device on the kernel side, but it's not a
MT device and it's not quite a tablet either. It uses slots to track up to 4
totems off the same device and the only hint that it's not a MT device is that
it sends ABS_MT_TOOL_TYPE / MT_TOOL_DIAL.

udev thinks it's a touchscreen and a tablet but we currently init those
devices as touchscreen (because all wacom tablet touch devices are udev
tablets+tochscreens). So we need a quirk to hook onto this device.

And we use a completely separate dispatch implementation, because adding the
behavior to the tablet interface requires so many exceptions that it's easier
to just add a separate dispatch interface.

981f3a47e6 quirks: add the ability to disable custom event codes/types
This is a more flexible approach than adding a model flag and the C code to
just call libevdev_disable_event_code(). There's a risk users will think this
is is a configuration API but there are some devices out there (e.g. the
Microsoft Sculpt mouse) that need a more generic solution.

Case in point: the Sculpt mouse insists on holding BTN_SIDE down at all times.
We cannot ship any quirks for that device because we only have the receiver's
generic VID/PID. So a local override is required, but we might as well make
that one generic enough to catch other devices too in the future.

5792af9a5f Implement a quirks system to replace the udev property parsing
Previously, we had all extra device information ("This is an Apple Touchpad",
"This touchpad causes pointer jumps", etc.) in the udev hwdb. The problem with
the hwdb is that updating it is nontrivial for the average user and debugging
when things go wrong is even harder. Plus, the hwdb has a matching scheme that
is unpredictable unless one is familiar with the implementation.

This patch set moves the hwdb entries into .ini style text files, with a
simple line-based parser. A new libinput list-quirks tool can list the quirks
applied to any given device, in --verbose mode it prints all matches as they
apply or not apply.

The data files are currently unused by libinput, that comes in a later patch.
They're installed though, the defaults point to the /usr/share/libinput
directory and for *temporary* local overrides the single file
/etc/libinput/local-overrides.quirks.

Failure to parse any file is a hard failure for the quirks system, but if the
local override file doesn't exist that's fine.

THIS IS NOT A CONFIGURATION INTERFACE! None of these settings are exposed via
the libinput_device_config_* calls. There is no API guarantee for these files,
think of them as source code.
