This adds a base class for SDCP devices. Not all functionality has been
fully tested, in particular the code to verify the model certificate is
most likely broken or incomplete. One problem there is that there is no
code to find the root CA to trust.
See: #257
To avoid conflicts with previous libfprint version and make sure that the
target version is the correct one (plus to allow parallel install in some
distros), let's use a versioned naming for the library keeping the abi
version in sync.
Fixes#223
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.
Add fpi_ssm_new_full() that allows to pass a name to the state-machine
constructor, not to change all the drivers, provide a fpi_ssm_new() macro
that stringifies the nr_parameters value (usually an enum value) as the name
so that we can use it for better debugging.
This allows to have an automatic cleanup of the timeout source when the
the callback is reached and to avoid to do further state changes in the
middle.
Meson files are normally using 4-spaces to indent and functions use first
parameter on the same line while others at next indentation level, not
following the parenthesis indentation.
So adapt libfprint to follow the meson standard.
Use the same approach of GTask, making possible to set the data from a
function. Givent the fact that a SSM has now a device parameter, it's
generally not needed to pass an extra data value.
In such case make it possible to set it and to define a destroy-notify
function to handle its destruction when freeing the SSM.
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.
This will allow us to segragate helper functions that we want to use
within NBIS. The first helper will be a macro checking for overflow in
multiplications.
In commit 231b8f9, when porting from doxygen to gtk-doc, we created a
section for "poll" functions, but we renamed that section to "events"
during the porting process. We ended up with an empty "poll" section,
and a correctly migrated "events" section.
Add fp_minutia_get_coords() so that debugging applications can show the
detected minutiae along with the captured image.
This will also help fix the positively ancient fprint_demo.

Not precise enough, and it was only used in upekts to get/set the
instance private struct and keep it around, so add a new, more precisely
defined field to fp_dev for that.
