We can avoid having multiple device feature-check functions now and
just rely on a few.
Add uncrustify config to properly handle begin/end deprecation macros.
It can be convenient for device users to check what it supports, without
having multiple functions to check each single feature.
So expose this and add tests.
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.
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
This was added as alias to the error check, but given we're passing to the
callback both the error and the match itself, we can just avoid adding an
extra parameter that could be confusing (as may imply that the matching
happened).
Also clarify the documentation and ensure that the match value is properly
set in tests.
It is a good idea to report match results early, to e.g. log in a user
immediately even if more device interaction is needed. Add new _full
variants for the verify/identify functions, with a corresponding
callback. Also move driver result reporting into new
fpi_device_{identify,verify}_report functions and remove the reporting
from the fpi_device_{identify,verify}_complete calls.
Basic updates to code is done in places. Only the upekts driver is
actually modified from a behaviour point of view. The image driver code
should be restructured quite a bit to split the reporting and only
report completion after device deactivation. This should simplifiy the
code quite a bit again.
When we notify the enroll progress with a print, this needs to be unreffed
once we're done, but this only was happening in case of error.
Since it's not up to the callback function to free it, let's do it at the
end of the function.
As per this, clarify the docs for FpEnrollProgress marking it as transfer
none.
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.
