This driver has a rather odd state machine and also used to mess iwth
the internal state of the image device. This code has been removed, but
is untested unfortunately due to a lack of hardware.
Most likely, this driver is not quite functional currently.
With this script it is possible to test libfprint/fprintd without any
hardware device. The image needs to be provides as a PNG with the alpha
channel storing the print data.
See the comment in the file on how the script can be used.
This is a rewrite of the core based on GObject and Gio. This commit
breaks the build in a lot of ways, but basic functionality will start
working again with the next commits.
Apply the previously added spatch/coccinell file to replace all
free/malloc/realloc calls with g_free/g_malloc/g_realloc. It also removes
all the error code paths that we do not need to check anymore.
This means that the returned data must be free'ed using g_free rather
than free, making memory management more consistent.

These PNGs were generated using gimp simply by using the greyscale image
itself as an alpha mask. The reason to do this is solely for easier
consumption together with cairo A8 surfaces.
We will not want to install virtual drivers by default, yet they should
be inside the "all" category. So add a new "default" category and also a
separate array for the future virtual drivers.
We will use GUsb rather than libusb directly in the future. This should
simplify a lot of the integration work and changes such as supporting
hotplugging. It will also require quite a lot of internal changes.
If one of the callbacks called from fpi_imgdev_deactivate_complete()
was reactivating the device, then we would be overwriting whichever
"action" got set in the callback, leading to
fpi_imgdev_activate_complete() failing as it doesn't handle the "none"
action.
Reset the action before calling the callbacks.
If a USB transfer is started but not completed in one go, the wdata we
pass to continue_write_regv() will already be freed by the time we try
to use it again.
Only free() the wdata on error, or when the USB transfer is completed.
Closes: #180
