New configuration API:
libinput_device_config_calibration_has_matrix()
libinput_device_config_calibration_set_matrix()
libinput_device_config_calibration_get_matrix()
libinput_device_config_calibration_get_default_matrix()
Deprecates libinput_device_calibrate().
For coordinate transformation, we're using a precalculated matrix. Thus, to
support ..._get_matrix() we need to store the original user-specified matrix
separately, in an unmangled state.

Basic tests for rotation, translation and scaling events.
Note that tests need to be added separately for single-touch and touch
devices, this is a restriction of the litest framework.

Fixed point numbers can easily overflow, and double to fixed point
conversion is lossy. Use floating point (double) where fixed point
numbers where previously used and remove the li_fixed_t type.

libinput currently handles 16 per device touch points. Test that we
behave as expected when a device has an even higher number of active
touch points.

Instead of having a test device which only purpose is to test absolute
coordinate transformation, use the litest_create_device_with_overrides()
API to create a specially crafted wacom touch device with high
resolution.

Instead of having one touch events representing different types of touch
events by providing a touch type, have one separate event type per touch
type. This means the LIBINPUT_EVENT_TYPE_TOUCH is replaced with
LIBINPUT_EVENT_TYPE_TOUCH_DOWN, LIBINPUT_EVENT_TYPE_TOUCH_MOTION,
LIBINPUT_EVENT_TYPE_TOUCH_UP and LIBINPUT_EVENT_TYPE_TOUCH_CANCEL.

Add a test case and test device that checks if the scale transform can
handle high resolution devices and output monitor resolutions.
The test case is created in a way that it will fail if the coordinate
transform expression will overflow if only 32 bit integer data
containers are used.
