The Dell Precision 5480 has a large touchpad without any visible markers
for the touchpad buttons.
Since the ModelTouchpadVisibleMarker quirk is enabled by default for all
Dell touchpads, the middle button area ends up being too small. Disable
the quirk for this specific model.

Some touchpads, notably those on the Dell XPS 15 9500, are prone to registering
touchpad clicks when the case is sufficiently flexed. Ignore these by
disregarding any clicks that are registered without touchpad touch.

Unlike in traditional touchpads, whose pressure value equals contact
size, on pressure pads pressure is a real physical axis.
We don't take advantage of the pressure information reported by
pressure pads yet, so we disable it to avoid errors.
Add a new model quirk for pressure pads instead of disabling
ABS_MT_PRESSURE and ABS_PRESSURE.

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.

Later versions of this same model seem to have a different ALPS touchpad
and don't need the pressure settings. Narrow down this match so we only
apply to the one from the actual bug report in #565.

Pressing Ctrl/Shift on this model triggers light touches that causes random clicks.
This doesn't occur on Windows 10 so adding this quirk to fix it

The default setting makes the "Dell Latitude E5510 TouchPad" too sensitive and
consequently difficult to use.
Note that the the size of the TouchPad is detected to be higher than it is
(the side-bars are half out of the TouchPad), see
https://github.com/systemd/systemd/pull/18493 for the hwdb overrides for this
device.

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.
