Benjamin Berg 9c8d062669 device: Handle full device storage including garbage collection 
The new libfprint version has support for devices that store data on the
sensor. In that case, the on-sensor storage might fill up when the user
tries to enroll a new print.

The strategy introduced here to handle this is to try and delete prints
from the device that we do not know about (assuming, it is e.g. from an
old installation and unusable).

It can also happen that we are not able to garbage collect old prints.
If that happens, a new error code "enroll-data-full" will be returned
signalling the situation to the enrolling application.

README 

fprintd
=======

https://fprint.freedesktop.org/

Daemon to offer libfprint functionality over D-Bus
Might eat your kangaroo.

Written in C.

Licensed under the GPL version 2 or any later version (see COPYING).

A PAM login module is included in the 'pam' directory.

API use cases
=============

- User wants to use the fingerprint reader, and enroll
  his fingerprints, or remove some fingerprints from the database

- Administrator wants to enroll fingerprints for a particular user,
  or remove fingerprints for a particular user

- Laptop/desktop authentication:
  * Check for fingerprint devices
  * Check whether a particular user has any fingerprints enrolled
  * Verify a fingerprint for a particular user, or, if the device
  supports it, verify that the fingerprint matches against
  any of the fingerprints enrolled

- Point Of Sale authentication (in a bar, the fingerprint reader is
  used to see who accesses a particular point of sale/till, in place
  of PIN code authentication and/or tokens)
  * Given a list of users, verify which one has scanned their finger
