This effectively disables the button scrolling, but since 0 is the default
button for most devices, we should allow setting the default button.

In some cases the compositor will want to know which buttons a device has.
E.g. for scrolling we want the compositor to be able to set a button to change
a relative device (e.g. a trackball) into scroll mode, so that it sends
scroll-axis events instead of pointer motion events.
In order for the compositor to be able to present a sane UI for this, it needs
to know which buttons a device has.

The previous code used delta/event as scroll trigger which roughly translates
to speed, but depends on the sampling rate of the device.
For slow two-finger motion, a user may move the height of the touchpad without
ever triggering scrolling. Change the _initial_ trigger to a cumulative
trigger, i.e. once the user moved past the threshold distance, scrolling
starts regardless of the speed.
Once scrolling is engaged, the original trigger of threshold/event is
required to engange the second scroll direction.
Note that except for really slow movements, it's very easy to engage both
scroll directions on a touchpad. This is intentional, libinput does not have
enough semantic knowledge to know if horizontal scrolling is needed. So we
provide some direction locking but not much, it's up to the
client/toolkit/widget to decide if both scroll directions should be handled.
Add a comment to clarify that in the public doc.

Natural scrolling is simply inverted scrolling, but I decided to

Add the usual quartett of config options for has/set/get/get_default/, as a

Only exposes one knob - speed, normalized to a [-1, 1] range with 0 being the
neutral "this is what we think is normal" speed. -1 and 1 reflect the
slowest/fastest reasonable speed on this device.
Note: with this API we commit to having any pointer accelerating as a true
gliding scale. We cannot map the [-1,1] range into a discrete set of steps
as we do not communicate to the caller whether a specific value has changed
the acceleration. Without that, a caller may assume that acceleration has
changed even when it is not visible to the user.

Rather than adding a config interface to disable a device merely allow a
caller to toggle the "send events" mode on the device. If off, the device
won't send events (though further events may be received depending on the
current state of the device).
Default is enabled, i.e. the device sends events.
A special mode is added to the obvious enable/disable: disable the device when
an external mouse is connected. Once set, the device will be enabled when no
mouse is present and stop sending events otherwise. This isn't hooked up to
anything yet though.
Built into the config API is the default option of "enabled". Any device
supports this, for the obvious reason. Disabling or conditionally disabling is
left to the implementation.

The big change here is the requirement to have the translation component in a
device-normalized coordinate space. Without that, we cannot reliably rotate as
the coordinate space is effectively unknown and may differ between the axes.
This affects any rotation matrix or translation matrix, pure scale matrices
were working just fine since they're unit-less.
Requiring the matrix in device-normalized space makes it possible for libinput
to rotate or otherwise handle the matrix independent of the screen resolution.
The rotation matrix is documented in a bit more detail to make it easier for
users to figure it out.
This changes the definition of the WL_CALIBRATION property (which is currently
broken).
