87dee93633 examples: Do not re-prompt the finger when repeating verification
Let's assume the user will want to re-scan the same finger rather than
being prompted again to change it.

516c1593bb examples: Continue verification when return is pressed
The message says [Y/n], but will not do Y by default. Fix this.

dcc7e6de90 examples: Save image even on match failure
Move the image saving out, so that it is always done when an image is
available. This allows viewing the image that corresponds to a match
failure.

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.

b46d336d2b examples: Add back examples using the async APIs
Add the examples back by using the new async API, support verification and
enroll for devices with own storage.

16875d7776 examples: Port enroll and verify examples to new storage
This ports the enroll and verify examples to the new storage so that
they do not need any deprecated API anymore.

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.

c1f8581ec9 Cleanup discover_device in examples
Andrei Tchijov pointed out that the discover_device() function is written
in a strange way.

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.

a86cd51959 Clean up on exit, and convert to singly-linked-lists
This adds fp_exit() to the public API, intended to be called while the
driving app is shutting down.

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.

Added 2 simple example programs to demonstrate this.

a verify example that loads from disk.

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.

verify a finger against it.
