Change calibration into a configuration option

Change calibration into a configuration option

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.
