Part of the big revamp to get rid of libinput_tablet_tool_axis and
replace it with a set of axis-specific APIs.
Only the rel wheel has true delta events, everything else is a delta
calculated by libinput based on the previous position. Since we supply that
position to the callers anyway, they can determine that delta themselves
where needed.

Part of the big revamp to get rid of libinput_tablet_tool_axis and
replace it with a set of axis-specific APIs.
Note that this commit drops the ability to check whether a tablet has an x or
y axis. If it doesn't, libinput won't initialize the tablet anyway so this was
superfluous already.
Likewise with the tilt axes - either we have x and y tilt or we have neither,
so separate checks for tilt_x and tilt_y is unnecessary.

Second part of the big revamp to get rid of libinput_tablet_tool_axis and

Note that this commit drops the ability to get the absolute value from a
relative wheel. The previous API always returned 0 for this case, it is not

The quartett of new config functions is:
libinput_device_config_accel_get_profiles
libinput_device_config_accel_get_profile
libinput_device_config_accel_set_profile
libinput_device_config_accel_get_default_profile
The profile defines how the pointer acceleration works, from a very high-level
perspective. Two profiles are on offer, "adaptive", the standard one we have
used so far and "flat" which is a simple multiplier of input deltas and
provides 1:1 mapping of device movement vs pointer movement.
The speed setting is on top of the profile, a speed of 0 (default) is the
equivalent to "no pointer acceleration". This is popular among gamers and
users of switchable-dpi mice.
The flat profile unnormalizes the deltas, i.e. you get what the device does
and any device below 800dpi will feel excruciatingly slow. The speed range
[-1, 1] maps into 0-200% of the speed. At 200%, a delta of 1 is translated
into a 2 pixel movement, anything higher makes it rather pointless.
The flat profile is currently available for all pointer devices but touchpads.

The previous approach to pointer acceleration was to initialize the same
motion filter behavior but a different acceleration profile depending on the
hardware (the profile converts a speed to a multiplier for input deltas).
To be more flexible for hardware-specifics, change this into a set of specific
pointer acceleration init functions. This patch has no effective functional
changes, they're still all the same.
The acceleration functions are kept for direct access by the ptraccel-debug
tool.

This reverts commit 8a6825f160.
Aside from introducing bugs, this doesn't really help with anything, it adds a
requirement to rename everything to make clear where we're using µs and where
we're using ms and that just clutters up the code.

There is no need here to use µs since we're just handling speeds/thresholds,
not actual events where a ms granularity can be too high.
Moving back to ms lets us drop a bunch of zeroes that clutter up the code, and
since the acceleration functions are a bit magic anyway, having the various
1000.0 factors in there makes it even less obvious.

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.

Extend the touchpad gesture API with pinch gestures. Note that this
new API offers a single event stream for both pinch and rotate data, this
is deliberate as some applications may be interested in getting both at
the same time. Applications which are only interested in one or the other
can simply ignore the other.
