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.
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.
Since GSource data can be automatically cleaned up on source destruction, we
can mimic this for the devices timeout easily as well.
Add an extra parameter, and let's use this cocci file to adapt all the
drivers like magic:
@@
expression e1, e2, e3, e4;
@@
fpi_device_add_timeout (e1, e2, e3, e4
+ , NULL
)
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.
