Benjamin Berg bc55deab2a device: Do not allow enrolling a finger that is already enrolled
This makes little sense. Users should delete the finger before trying to
enroll the same one again. So throw an error at them from EnrollStart
right away.

Fixes: #95

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
