Not all mice have a click angle with integer degrees. The new
MOUSE_WHEEL_CLICK_COUNT property specifies how many clicks per full rotation,
the angle can be calculated from that.
See https://github.com/systemd/systemd/pull/4440 for more information
CLICK_COUNT overrides CLICK_ANGLE, so we check for the former first and then
fall back to the angle if need be. No changes to the user-facing API.

open_restricted() doesn't always mean 'open the fd'. When the X server uses
systemd-logind, the fd is opened once before PreInit and then kept open across
devices being disabled and enabled through the protocol.
When the device is re-enabled and libinput_path_add_device is called for the
device, we may have events pending on the fd, leaking information that we
should just ignore.
There's also the potential of inconsistent state. The kernel updates the
device state whenever it processes an event, the evdev ioctls return that
state. If events are pending, the state we see is newer than the events we
process immediately after initialization. That can lead to confusion.

In order to provide higher precision event time stamps, change the
internal time measuring from milliseconds to microseconds.
Microseconds are chosen because it is the most fine grained time stamp
we can get from evdev.
The API is extended with high precision getters whenever the given
information is available.

To quote Bryce Harrington from [1]:
"MIT has released software under several slightly different licenses,
including the old 'X11 License' or 'MIT License'. Some code under this
license was in fact included in X.org's Xserver in the past. However,
X.org now prefers the MIT Expat License as the standard (which,
confusingly, is also referred to as the 'MIT License'). See
http://cgit.freedesktop.org/xorg/xserver/tree/COPYING
When Wayland started, it was Kristian Høgsberg's intent to license it
compatibly with X.org. "I wanted Wayland to be usable (license-wise)
whereever X was usable." But, the text of the older X11 License was
taken for Wayland, rather than X11's current standard. This patch
corrects this by swapping in the intended text."
libinput is a fork of weston and thus inherited the original license intent
and the license boilerplate itself.

There is quite a wide spread in the delta events generated by trackpoints,
some generate deltas of 1-2 under normal use, while others generate deltas
from 1-20.
It is desirable to normalize trackpoint deltas just like we are normalizing
mouse deltas to 1000 dpi, so as to give different model laptops aprox.
the same trackpoint cursor speed ootb.
Recent versions of udev + hwdb set a POINTINGSTICK_CONST_ACCEL udev property
which can be used to adjust trackpoints which are too slow / too fast
ootb, this commit implements support for that property.

Not all touchpad kernel drivers supply the x/y resolution. Let the udev hwdb
fix this up where possible and read the value from it.
This is intentionally only used on touchpads, touchscreen devices without
resolution should be considered buggy and fixed in the kernel.

Added: udev-tag detection for the tablet.
libwacom assigns ID_INPUT_TABLET to all known devices but also
ID_INPUT_TOUCHPAD to all known devices with a touch interface. That's a bug
and should be fixed there but we can work around it by checking both and
making sure only one is set.

Makes the code use more commonly used paths, no real functional changes at
this point. This was using hand-crafted devices as it predates the
litest_add_for_device() helper.
For an upcoming patch to use the udev ID_INPUT_. tags the
event_conversion_key test requires this change: without it the device will be
tagged with ID_INPUT_KEY but not ID_INPUT_KEYBOARD. This could be fixed by
adding all normal keyboard keys to the uinput device but it's easier to just
re-use litest.
