For certain applications (such as FPS games) it is necessary to use
unaccelerated motion events (the motion vector that is passed to the
acceleration filter) to get a more natural feeling. Supply this
information by passing both accelerated and unaccelerated motion
vectors to the existing motion event.
Note that the unaccelerated motion event is not equivalent to 'raw'
events as read from devices.

The libinput device abstracts a number of things but sometimes the underlying
device is important. The udev device provides the necessary handle to access
that underlying device and various sysfs properties that may be necessary.
A function returning the device node would've done the same thing but is more
prone to race conditions than the udev_device.

400 used to be the default DPI for many mice but it it's not anymore. A survey
of mice shows that 400 is still common as one of the pre-configured settings
in switchable multi-resolution gaming mice, but devices with a single
resolution mostly favor 1000 dpi.
Let's make that switch now so that any future changes to the pointer
acceleration code assumes that resolution as a default.
For the touchpad, this has a bad side-effect, caused by our expectation of
mouse vs touchpad behaviours: our acceleration code ignores device type and
provides the same acceleration for the same physical movement. Unfortunately,
we expect touchpads to be significantly slower than mice.
The previous 400 DPI worked because it caused an acceptable slowdown on input.
e.g. on the T440 with a res of 42 units/mm, the scale coefficient was 0.37.
For 1000 DPI as default, this now results in 0.94, i.e. speeding up the
touchpad by a factor of 2.5. That is way too fast.
Adding touchpad-specific filter code is a bigger project, so let's just add a
fixme for now and scale the coefficient back to what it was before the
DPI default change. Effect: touchpad behaves as before.

The filter code is what relies on some default dpi configuration to apply
pointer acceleration and expects the input coordinates to be pre-scaled to
that resolution.
Let's move the define here so we can use it from the touchpad code too.
No functional changes.

Add edge-scrolling support for non multi-touch touchpads as well as for
users who prefer edge-scrolling (as long as they don't have a clickpad).
Note the percentage to use of the width / height as scroll-edge differs from
one manufacturer to the next, the various per model percentages were taken
from xf86-input-synaptics.

The seat of a device is currently immutable, but a device may (in a
multi-pointer case) move between different logical seats. Moving it between
seats is akin to removing it and re-plugging it, so let's do exactly that.
The physical seat name stays immutable.
Pro:
- device handling after changing a seat remains identical as handling any
other device.
Con:
- tracking a device across seat changes is difficult
- this is not an atomic operation, if re-adding the device fails it stays
removed from the original seat and is now dead

Potential race condition:
- udev notifies us that a udev_device became available
- we go for a coffee and chat to the neighbours on the way
- the device is unplugged
- a new device is plugged in, gets the same devnode
- we finish our coffee and come back
- open(udev_device_get_devnode())
- new device is now opened as the old device
To avoid the above race, we compare the syspath of the device at the open fd
with the syspath of the device we originally wanted. If they differ, we fail.
evdev_compare_syspath was simply moved up.

Using a udev_device instead of the various bits separately safes us
