This changes the cancellation logic a bit to ensure we always deactivate
the device (equivalent to the AWAIT_OFF state in the driver). All
commands except for the deactivation command should be cancelled when an
operation is stopped, this is to ensure that the LED is turned off at
the end of an operation.
The state was always AWAIT_FINGER and it was never used by any driver
(except for error checking). So remove it, in particular as a correct
state change will be done after activation anyway.
The only driver with code that actually did anything based on this was
the URU4000 driver. However, all it did was an explicit state change
execution. This is not necessary, as the state_change handler is called
anyway (i.e. we now only write the AWAIT_FINGER register once rather
than twice).

Check for the mean calibration being outside of range to know whether we
require a recalibration. Continue with the usual checks if the
calibration value is within range.
The dimensions some sensors return is the maximum zero-based index
rather than the number of pixels. Assuming every sensor has an
even number of pixels is safe.

Pass the struct fp_dev and user_data to fpi_ssm callbacks, so that we
might be able to get rid of the fpi_ssm_get_user_data(), and
fpi_ssm_get_dev() as most drivers just get those from the ssm anyway
in their callbacks.
There has been a report that a 0x0c03 was installed straight (other
readers so far have produced images that are 90 degrees rotated). There
is no way for the dirver to know how a device is installed, so for now just
make an exception.
Sensor reset code has been removed because it is not needed during normal
operation.
Calibration and frame processing logic has been improved according to
recommendations from Elantech.
Make each command a separate struct to get finer control over which
commands are called on which devices. Update ssm's accordingly. Add
sensor_reset and fuse_load commands.
Support 0x0903, 0x0c03, 0x0c16, 0x0c1a, 0x0c26
Remove all the headers already included through "fp_internal.h" such as
<libusb.h> and <errno.h>, include "assembling.h" and "driver_ids.h" there
as well to avoid doing it in (almost) every driver.
