The elan driver converts frames into a different format. These frames
are only needed to assemable the image and should be free'ed afterwards.
Fixes: #213
The manage-prints command would close the device twice when the user
hits an invalid number or 'n' and no prints need to be deleted.
Simply remove the erroneous call to fix the issue.
The private library needs to indirectly include fp-enum.h. This
dependency was not listed anyway, resulting in a race condition during
the build process.
While timeout was already cleared for parent, we didn't properly delete the
cancellable.
Although we'd warn anyways when starting the SSM, is still better to clear
any delayed action also for the sub-SSM
Since tests depending on the fake device don't depend on virtual-image
driver anymore, let's change the way we organize the things, by putting
everything in the test lib, but enabling unit-tests depending on what they
depend on.
Use the virtual image device as base for now, while the new setup allows
to create easily fake device drivers without including the driver in
libfprint itself and test all the fpi_device functionalities.
In order to be able to test the private device code (used by drivers) we
need to have that split a part in a different .c file so that we can compile
it alone and link with it both the shared library and the test executables.
Redefine fp_image_device_get_instance_private for private usage, not to move
the private struct as part of FpDevice.

A Fp-device use an union to track the handle to the lower-level device, and
the value depends on the object type.
So in case of using a virtual device, the priv->usb_device location matches
the priv->virtual_env string location, and thus we'd end up unreffing a
string location as it was a GObject, while we'd leak the string.
To avoid such errors, instead of just checking the device type when we
finalize the device, let's just use different pointers to avoid other
possible clashes.
This fixes the the problem that the sensor becomes unresponsive after
pressing the wrong fingerprint. We fix the problem by making sure that
the non-match report is delayed until the finger is removed. With this
we cannot run into the situation that the next match request fails
immediately as the finger is still present.
Fixes: #208
The FPI_MATCH_ERROR constant was set to 0, however it is propagated to
the task completion using g_task_propagate_int. As g_task_propagate_int
will always return -1 on error, we either need to add an explicit -1
check or we just need to match the semantics.
Change the constant to -1, also rearange FP_MATCH_SUCCESS so that it
does not end up being 0.
This also changes the code to keep the connection open and adds
automatic mainloop iteration to ensure the driver processes the request.
This is important so we will not deadlock when we send multiple
requests.
Add commands to disable automatic finger reporting for images and to
send a specific finger report. This is useful to test more code paths
inside the image-device code.
