When a transfer is completed, we automatically unref it since we can't
consider it valid anymore since this point.
Update the drivers not to free the transfer after submitting anymore.
When a machine is completed, we automatically free it since we can't

Update the drivers not to free the SSM on completion callback anymore.
Use the same approach of GTask, making possible to set the data from a
function. Givent the fact that a SSM has now a device parameter, it's
generally not needed to pass an extra data value.
In such case make it possible to set it and to define a destroy-notify
function to handle its destruction when freeing the SSM.
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).

identifier driver_name;

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.
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.
ID is just a some magic number to make fingerprint from one scanner model
incompatible with another scanner model. Get rid of "magic", declare enum
and use it.
