587131a6bd drivers: Use more fpi_ssm_usb_transfer_cb when possible
Replace all the transfer callbacks where we just switch to the next state or
fail with fpi_ssm_usb_transfer_cb.

2642fc6560 fpi-usb-transfer: Take ownership of the transfer when submitting it
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.

a855c0cc79 fpi-ssm: Take ownership of the SSM when completing it
When a machine is completed, we automatically free it since we can't
consider it valid anymore since this point.

Update the drivers not to free the SSM on completion callback anymore.

7bc62821ee ssm: Make possible to set data via function
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.

4cec28416e lib: Remove state from fp_img_driver activate handler
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).

Manual changes plus:

@ init @
identifier driver_name;
identifier activate_func;
@@
struct fp_img_driver driver_name = {
    ...,
    .activate = activate_func,
    ...,
};
@ remove_arg @
identifier dev;
identifier state;
identifier init.activate_func;
@@
activate_func (
	struct fp_img_dev *dev
-	, enum fp_imgdev_state state
	)
{
	<...
-	if (state != IMGDEV_STATE_AWAIT_FINGER_ON) { ... }
	...>
}

10ae8ffb55 drivers: Simplify libusb_alloc_transfer(0) calls
By using our new, never-failing, USB allocation wrapper. As it can never
fail, we can also remove all the error paths for the allocations
failing.

0c3a22758b drivers: Simplify FP_INSTANCE_DATA(FP_DEV()) calls
When fp_dev is already available, don't use the fp_img_dev struct to get
to fp_dev with FP_DEV(), use the fp_dev directly.

9cc859a318 drivers: Diminish fpi_ssm_get_user_data() usage
Can't remove it yet, as libusb transfers and timeouts don't pass the
fp_dev or fp_img_dev separately.

e397571f83 lib: Add more args to fpi_ssm callbacks
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.

994061af44 drivers: Simplify headers

<libusb.h> and <errno.h>, include "assembling.h" and "driver_ids.h" there
as well to avoid doing it in (almost) every driver.

32fcfde86b lib: Use GLib and libusb directly for debug output
Use GLib internally to output debug information, and tell about
libusb's LIBUSB_DEBUG envvar for libusb debug.

fp_set_debug() is now a no-op.

ea6d5ba6d6 lib: Fix mess with driver IDs
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.

handles. This allows front-ends to direct the user better.
