a3f568db3d fp-context: Check hidraw VID/PID with udev instead of an ioctl
Previously, we checked hidraw devices against drivers by using the
HIDIOCGRAWINFO ioctl. While this works, it's not ideal for doing unit
tests since umockdev would have to implement hidraw ioctls.

The new approach uses the HID_ID property on the parent hid device,
which contains the VID/PID pair.

94e86875ae context: Remove idle sources and use thread local context
libfprint uses the thread local context in almost all cases. Update
FpContext to also use it and make sure that any sources are removed when
the FpContext object is finalized. Otherwise we may run into
use-after-free issues.

511d456006 context: Use g_signal_connect_object for removal handling
Technically the API user might not keep the FpContext around after getting
the device object. Really bad idea, but we shouldn't rely on that.

b0d9d00762 Add support for udev based device discovery
This is primarily useful for SPI devices. These devices sometimes needs
a combination of an SPI and HID device, so discovery is a bit more
complicated.

b6dd522459 Rework device removal to have a nice API
This enhances the device removal to create a well defined behaviour.

Primarily, it means that:
 * "device-removed" will only be called for closed devices
 * "removed" will be called only when no operation is active

Note that all actions will fail with FP_DEVICE_ERROR_REMOVED, *except*
for open which will only return this error if it failed.

Resolves: #330

5d0481b031 context: Lower severity of warning if USB fails to initialise
This is unlikely to happen in a real world scenario and currently breaks
running the CI test (not the umockdev based ones) while building the
flatpak. Lower the severity to avoid aborting because there is a
warning.

596d22a449 context: Fix invalid accesses to GUsbContext if USB is missing
When USB cannot be initialised (inside the flatpak build environment),
then we would have invalid accesses to the NULL pointer. Fix those.

eefc954f91 context: Fix order of PID/VID in a debug message
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.

5b17eda011 Prefix internal properties/signals with fpi- and annotate them
We prefixed them with fp- which is not as obvious as fpi-. Also,
explicitly mark them as private and to be skipped in the GObject
Introspection annotatinos.

eeddd8c7bc fp-context, tools: Use auto-ptr to handle GTypeClass ownership
This also fixes a small leak we might have if reffing a type that was not a
virtual one.

This avoids that we pick unwanted drivers when running the tests in a
machine that has some supported device attached.

5dc3edf07c fp-context: Run dispose on the usb context to deal with circular refs
Ensure that we dispose the USB context before unreffing it, so that it will
release any reference it has and destroy the internal libusb context.

689aff0232 lib: Major rewrite of the libfprint core and API
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.
