099fa9f005 meson: Use preferred syntax everywhere
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.

1319daba54 examples: allow to select multiple devices
Since there might be external USB readers and embedded ones, better to allow
easily to select them all in examples.

39e3e2b794 examples: Move discover_device function to utilities
While there are various functions which similar usage in all the examples,
I'd prefer to keep each example to be self-containing most of the things.
However some clearly repeated action can be moved to a single codebase.

cddd0f4653 examples: Remove old verify_live example
The example has not been ported and it is not very useful as verify
already shows how everything works.

256c7cea07 examples: Remove x11 based examples
These examples have not been ported. In addition, they are also not very
useful these days, as the demo application offers a much nicer view to
view images from a sensor.

dd40aeaa79 examples: Add sendvirtimg.py script to send a print to virtual_imgdev
With this script it is possible to test libfprint/fprintd without any
hardware device. The image needs to be provides as a PNG with the alpha
channel storing the print data.

See the comment in the file on how the script can be used.

9b175a7681 examples: Add PNGs for NIST example prints
These PNGs were generated using gimp simply by using the greyscale image
itself as an alpha mask. The reason to do this is solely for easier
consumption together with cairo A8 surfaces.

0a45ed7af6 data: Deprecate print storage API
The only API user currently seems to be the examples. fprintd has its
own storage and that will be a good idea in general.

So deprecate the API, we'll need to find a different solution for the
examples eventually.

6ba9439bbb examples: Remove sleep call in enroll examples
The call to sleep(1) inside of the enrollment loop caused a crash
on at least the etes603 driver.

Because in fp_enroll_finger_img the function enters an event
handling loop. This loop needs to start before the next libusb
event timeout. Which would not happen in the etes603 driver
because the timeout there was set to 1 second as well.

014b933b2b Add gdk-pixbuf support
When imaging support is required, we prefer to use gdk-pixbuf,
as it's already on things like Live CDs.
Also fix the examples building against the system libfprint.

5485f8031d Return images through enroll/verify path
Added new API functions to obtain images, even when scans are bad, perhaps
a useful way to show the user just how good/bad the scan actually was.

Drivers and examples updated accordingly.

2709c6dc8c Basic image driver foundations
The basic model is that image drivers declare a fp_img_driver structure
rather than a fp_driver struct. fp_img_driver will contain primitive imaging
operations such as 'scan finger and return image'. The imgdev layer will
generically implement the primitive fp_driver operations, and the imgdev
layer will fix up the enroll/verify/etc pointers at driver registration
time.

Removed const from all fp_driver declarations, as these are now modified
dynamically in the case of imaging drivers.

680142f268 storage: add save/load functionality
Prints can now be saved to disk (but you currently must classify which
finger they are) and you can load them later.

39271b4fe5 Enrollment: improved error reporting
Convert enrollment function to return a signed integer, which is negative
on error or corresponds into fp_enroll_result otherwise.
Now we can treat a 'FAIL' condition differently from an actual error: fail
means that enrollment didn't complete because the data was nonsense or
whatever (e.g. scanned a different finger for each stage?).

Updated upekts accordingly.

50e2de0730 Enrollment tweaks
upekts will need to know when the first enrollment stage is attempted for
the first time, so add an __enroll_stage counter which actually indicates
the next stage to enroll. -1 is a special value and it means 0 is next *and*
it is the initial attemt.

Added more debug output to the enroll handler.
Added new fp_enroll_status codes for too short or uncentered scans.

Changed the print_data allocator to consider the device rather than the
driver, this feels more natural. Added missing return value.

Make fp_enroll_status codes start at 1. 0 can now be used as a
special/temporary value by the drivers. Also check that we aren't exceeding
the number of enroll stages.

Also add a missing exit() call to the verify example and update for the
above.
