EvdevAddDevice/EvdevRemoveDevice keep a reference to the device to detect
duplicate devices based on the dev_t.
EvdevAddDevices was called during PreInit, EvdevRemoveDevice was called during
DEVICE_CLOSE. That makes it imbalanced if the device succeeds PreInit but the
server skips everything else because MAX_DEVICES is exceeded. So for all
devices after MAX_DEVICES, we'd add a reference but never remove it,
eventually reading/writing past evdev_devices.
The server keeps the list of devices for us anyway, so remove the copy of all
the pointers and instead run through the device list the server gives us.

This was the original behavior introduced in
f77410e1f9 and stayed that way until smooth
scrolling erroneously added it as vertical axis in
b450efdf95. Revert to horizontal scrolling to
restore the previous behaviour - which unbreaks scrolling on Microsoft mice.
This effectively reverts 54a3120e33 too.

wheel emulation, for some reasons beyond time, got the value from
pEvdev->vals, then set the value back into pEvdev->vals. Alas, that value is
always 0, hence oldValue is zero and the delta is nil.
If we're not in relative (touchpad) mode, store the current value in
old_vals, so they're retrievable for the next event.

Removes the need to ioctl manually and check bits, with all the dangers that
come with that. libevdev is much better prepared for invalid values, OOB
checks, etc.
Plus, we get almost free SYN_DROPPED handling as well which we didn't have
before.

If a device has ABS_MT_SLOT, mtdev merely reads the events and returns them
to the caller as-is. For this we don't need mtdev, we can just handle those
events ourselves.
This patch switches to the mtdev plumbing layer that takes events and
converts them instead of reading them off the fd.

When writing LED values to the device, append a SYN_REPORT to the list to
ensure other clients are updated immediately. Otherwise, the LED events
will be queued and not sent to other clients until the next input event

As of xkeyboard-config 1.9, the evdev model is hidden (c887d2876)
The server switched to pc105 with version 1.8 (1df4bd601).
The evdev model resolves to pc104 anyway, so this commit has no real effect
other than to switch from a catch-all rule to explicit.
Use pc104 so this is easy to find for those investigating the code and
wondering why. pc104 is the 'correct' geometry for the us layout, which is
the default after all. Switching to pc105 would show keys missing if no
model is set (e.g. on uk/de layouts) but it would be the wrong layout for
the default.

The kernel should give us ABS_X/Y for backwards compat but some devices
don't. For now, ignore these devices as evdev is not suited to handle this
yet and will crash if a device is set up without axes (i.e.
pEvdev->vals == NULL) and later receives an event from an MT axis.

evdev tries to assign the right XI 1.x type-name based on various device
capabilities. In some cases, that fails. e.g. the Mionix Naos 5000 mouse
looks like a keyboard. And we assign a keyboard type in that case since
there are plenty of keyboards that also advertise some axes or others.
Add a new option TypeName to allow for system-wide configuration of such
devices in a quirks file.
This can also be used to address #55867

FALSE == Success, so if we fail during EvdevOpenMTDev, the caller thinks
that everything worked fine, proceeds to set up the fd, etc.
This may later cause a crash, when a device comes back later as different
device and posts axis events where we didn't configure axes in the first
place.
Note: Unclear why there was no udev event received for the device being
removed and coming back as different device though.

Fixes regression introduced in 2f67509b53.
If evdev is used for touchpads, the abs axis movement is converted to a rel
movement. Without the two relative axes initialized, the events are
discarded.
Axes 0 and 1 are always x/y anyway unless specifically configured otherwise.

We expect at least BTN_TOUCH for anything with MT axes, but devices that
don't have that need a button class regardless. Some gamepads define
MT axes but no buttons, causing a bug in the server when they post a
TouchBegin.
