device: Add API for perstistent data storage

API consumers should fetch the persistent data when they are done and store it to disk. It is undefined when this data is updated by the driver, but in general, it should only be updated once the first time a device is used.

+libfprint is part of the fprint project:
+https://fprint.freedesktop.org/

 ## History

-**LibFPrint** was originally developed as part of an
-academic project at the **[University Of Manchester]**.
+libfprint was originally developed as part of an academic project at the
+University of Manchester with the aim of hiding differences between different
+consumer fingerprint scanners and providing a single uniform API to application
+developers. The ultimate goal of the fprint project is to make fingerprint
+scanners widely and easily usable under common Linux environments.

-It aimed to hide the differences between consumer
-fingerprint scanners and provide a single uniform
-API to application developers.
-
-## Goal
-
-The ultimate goal of the **FPrint** project is to make
-fingerprint scanners widely and easily usable under
-common Linux environments.
+The academic university project runs off a codebase maintained separately
+from this one, although I try to keep them as similar as possible (I'm not
+hiding anything in the academic branch, it's just the open source release
+contains some commits excluded from the academic project).

 ## License

-`Section 6` of the license states that for compiled works that use
-this library, such works must include **LibFPrint** copyright notices
-alongside the copyright notices for the other parts of the work.
+THE UNIVERSITY OF MANCHESTER DOES NOT ENDORSE THIS THIS SOFTWARE RELEASE AND
+IS IN NO WAY RESPONSIBLE FOR THE CODE CONTAINED WITHIN, OR ANY DAMAGES CAUSED
+BY USING OR DISTRIBUTING THE SOFTWARE. Development does not happen on
+university computers and the project is not hosted at the university either.

-**LibFPrint** includes code from **NIST's** **[NBIS]** software distribution.
+For more information on libfprint, supported devices, API documentation, etc.,
+see the homepage:
+https://fprint.freedesktop.org/

-We include **Bozorth3** from the **[US Export Controlled]**
-distribution, which we have determined to be fine
-being shipped in an open source project.
+libfprint is licensed under the GNU LGPL version 2.1. See the COPYING file
+for the license text.

-<br/>
+Section 6 of the license states that for compiled works that use this
+library, such works must include libfprint copyright notices alongside the
+copyright notices for the other parts of the work. We have attempted to
+make this process slightly easier for you by grouping these all in one place:
+the AUTHORS file.

-<div align="right">
+libfprint includes code from NIST's NBIS software distribution:
+http://fingerprint.nist.gov/NBIS/index.html
+We include bozorth3 from the US export controlled distribution. We have
+determined that it is fine to ship bozorth3 in an open source project,
+see https://fprint.freedesktop.org/us-export-control.html
