1b5dd0057f tests: Add device removal test
This tests all relevant scenarios of device removal, i.e.:
 * device is not open
 * device is currently closing
 * device is open and idle
 * device is currently opening
 * device is open and active

The test ensures that in all scenarios the following holds true:
 * device "removed" signal is only emitted after the action completes
 * context "device-removed" signal is only emitted after the device has
   been closed

Note that the "opening" case is special. Here we confirm that a success
from "open" will not be overriden by a FP_DEVICE_ERROR_REMOVED error, in
order to correctly signal that the internal device state is open and it
needs to be closed.

8a6f1932f8 virtual-image: Add a notify::removed handler
In general, we rely on the underlying transport layer to throw errors
which will abort the current operation. This does not work for the
virtual image device though, but we need it there for testing purposes.

Add a notify::removed handler that makes things work as expected. Let it
throw a protocol error which should not be visible to the outside.

0051ff6352 device: Treat devices as closed even after a close failure
We require the close call, but as the underlying transport layer is
gone, it will generally just return an error.

In principle, it makes sense to think of close as a function that always
succeeds (i.e. it makes no sense to try again). Should the device be in
a bad state, then a subsequent open() will simply fail.

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

656bf3d175 elan: Add a few comments that stopping/callibrating helps
Apparently stopping/callibrating helps with the reliability of these
sensors. Add a few comments so that this information is known.

fe498c56c7 virtual-image: Fix race condition closing new connection
When a new connection came in we would close the old connection. This in
turn would trigger a receive error causing the *new* connection to be
closed from the error handler.

Fix this by simply cancelling any pending transfers when a new
connection comes in. Also change the error handling code to catch issues
like partial writes correctly.

This fixes an issue for the fprintd test where some tests were flaky.

3b993fabb6 verify/enroll: Save and use locally saved prints also for devices with storage
Some devices have storage but that's is limited enough not to be able
to store all the metadata, but just a fingerprint id.

In such case we also need to use the local storage to be able to verify.
Fprintd does this already, but we don't do it in the libfprint examples.

So, in in case we enroll, always save the print information to the disk,
while in case we verify we try to load the print from disk and we use
that in case its private data matches the one provided by the device.

893ff9c033 fp-image-device: Report finger status changes to the device

4f29a32da8 tests: Store temporary directory on failure
It is not very useful to just delete the data again after a failure, as
it might be useful for debugging. Just store it into an "errors"
subdirectory of the PWD in the hope that this is a sane location.

Note that it'll error out if the directory already exists, but that
should be acceptable in all cases. i.e. it won't exist in the CI and
developers can just wipe the directory.

d3076039d0 vfs301: Fix device pointer handling in callback
When porting the driver to the new libfprint 1.90.0 a mistake was made

still read from there. Stop using user_data in the callback to fix this.

a748f4d30f elan: Simplify elan driver internal state machine
The elan driver always "deactivates" the device after a cpature run. We
can simplify the while internal state into a single "active" state and
rely on the image device driving this state machine correctly.

i.e.:
 * We start a callibrate/capture/deactivate when we go into the
   AWAIT_FINGER_ON state
 * We only store the fact that we are active and want to deactivate
 * We rely on the image device never going into the AWAIT_FINGER_ON
   state without first waiting for the finger to be off (which implies
   deactivation).

3ee5536a13 image-device: Redefine internal states and valid transitions
This adds a number of new internal states to better capture what is
going on. Also added are checks that all transitions we make are in the
set of expected and valid transitions.

Only three drivers use the state_change notification. These drivers are
updated accordingly.

f56aacc7ef image-device: Remove cancelling boolean from private data
The boolean is just used to emit a warning for unexpected state

96fa0a96eb uru4000: Fix missing reference to image transfer

was implicitly removed after the transfer completed. Add a new reference

handler.

33d50e4e30 usb: Annotate access to USB buffers
Annotate the USB transfer creation functions with the correct buffer
access attribute. Note that we only annotate them as read_only as the
functions may be used for sending and receiving.

Hopefully this will catch buffer overflows in drivers in the future.

994690cfa3 virtual-image: Only read socket when active
Doing this avoids race conditions in testing code where the code might
try to submit errors/images before the device has been activated. This
would then (sometimes) trigger assertions in the image driver code.

52b2d10887 image-device: Delay task completion until device is deactivated
The earlier image device code tried to hide deactivation from the
surrounding library. However, this does not make any sense anymore with
the early reporting feature present.

This changes the operation to complete only once the device is
deactivated. Also changed that in most cases (except for cancellation)
we wait for the finger to be removed before deactivating the device.

81e0f4dfe5 aes3k: Re-send some commands for each capture
The driver seems to have relied on the device to be fully
deactivated and activated again for each capture. This is not the case
during enroll, and as such in can cause issues.

Try fixing this by splitting out the last few commands send to the
device and assuming that this starts the capture.

c7cab77fc1 usb-transfer: Work around libgusb cancellation issue
We have plenty of code paths where a transfer may be cancelled before it
is submitted. Unfortunately, libgusb up to and including version 0.3.6
are not handling that case correctly (due to libusb ignoring
cancellation on transfers that are not yet submitted).

Work around this, but do so in a somewhat lazy fashion that is not
entirely race free.

bcce8876e2 aes3k: Fix cancellation logic of aes3k driver
The change_state function is called synchronously from the
image_captured callback. This means that deactivation of the device
happens during the img_cb function, causing the USB transfer to be
re-registered even though the device is already deactivating.

There are various ways to fix this, but it makes sense to directly bind
the cancellation to the deactivation. So create a cancellable that we
cancel at deactivation time, and make sure we always deactivate by going
through cancellation.
