Has 2 variants, one that supports identify, one that doesn't.
The mode of operation for this device is:
- Run fprintd with "FP_VIRTUAL_DEVICE=/tmp/fprint.socket"
- As root:
FP_VIRTUAL_DEVICE=/tmp/fprint.socket ./sendvirtcmd.py "ADD left-middle testuser success"
FP_VIRTUAL_DEVICE=/tmp/fprint.socket ./sendvirtcmd.py "ADD right-middle testuser failure"
- As testuser:
fprintd-enroll -f left-middle-finger
fprintd-enroll -f right-middle-finger
Now, across fprintd restarts (as it has its own storage), verification
will always succeed for user "testuser" with the "left-middle-finger".
Using the FP_VIRTUAL_DEVICE_IDENT envvar instead will allow
identification, with the first found "successful" finger being presented
as the identified one.
Rather than requiring a driver to implement a variant with
identify support, and another one without, ask the driver whether a
particular device supports identification.
When no driver is found for an USB device a debug message is
printed. However, it has PID and VID in wrong order - usually it
is Vendor ID which goes first. This is how 'lsusb' prints it.
Matching the order helps debugging.

In the fpi_print_fill_from_user_id() GDate is defined using
g_autoptr(). However, this requires new enough GLib. For older
versions there's a definition provided locally in fpi-compact.h.
Include the file to fix build with older version of GLib.

If we fail when setting the scanned image to a print, we'll have a fatal
error, in such case we can terminate the current action and deactivate the
device.
In some cases nbim's get_minutiae returns no minutiae without providing an
error code, and if this happens we would crash in the task callback function
as we would try to deference the data->minutiae pointer.

If the image height is less than the sensor horizontal resolution, then
return a retry error rather than trying to submit the image for further
processing.
Related to: #251
The minutiae detection might fail and we must not copy any data at that
point. So check g_task_had_error to ensure that we only do so when the
task was successful.
Fixes: #251
During verify/identify complete we replace the error pointer that the driver
returned with another error we created, after clearing that one.
However, when we initialize a new error the compiler may reuse the same
allocation of the cleared one, and this might lead to a test failure.
So, don't be so fragile and ignore the pointer check

The unittest_parser script would try to import FPrint gi module, but it
would fail as per the fact that none is installed yet, so make sure that
we don't load any FPrint module until we try to actually run the tests
The public API uses gio and gobject header, ensure that these are in the
list of Required pkg-config modules, otherwise they are added to
Required.private which is not OK.
It appears the order of linking is relevant in this case, change it to
fix some linking issues.
It may be that there are better solutions to this problem.

Devices with no storage don't allow listing prints, and if we try to do
that, we'd end up in trying to call a NULL function pointer, causing a crash
So always check if the device has storage before calling the list vfunc, and
if we fail, return an error.
Include an unit-test to verify this situation
