---
Fingerprint: Make the existing FingerprintService semi-useful.

- Add explicit actions for authentication so HW has
  a chance to power down when not in use.  The other
  option would be to start scanning when startListening
  is called, but that would force apps trying to enroll
  to start trying to authenticate immediately before they
  start enrollment.  That didn't seem like a good idea.
- Update to CM Fingerprint HAL 1-1.
- Extreme care needs to be taken to use this
  API.  It's not exactly robust against multiple
  clients stepping on each other.
- All of this goes away in M.

Fingerprint [1/2]: Numerous Fingerprint Improvements

1. Introduce getEnrolledFingerprints
2. Introduce Fingerprint object to track name/id/userid
3. Store fingerprints in global settings instead of per user.
   This is because vendor implementations are also global.
4. Give newly enrolled fingerprints a default name.
5. Allow fingerprint names to be changed
6. When getting fingerprint data, merge the native stored fingerprints data
   with settings provider fingerprint data.
   - This is because the vendor will store the actual fingerprint, but all the
     metadata is stored by the provider.
7. Provide basic dump commands in fingerprints

Too short with current time. UX wants the messages to last longer.

Fingerprint: Reset state when client cancels

Otherwise it is possible for the service to get stuck in
a non-idle state if the current task never finishes properly.

Add fingerprint to DB before calling clients

Some clients may call getEnrolledFingerprints when they receive
onEnrollResult.  If the settings database is not updated before
that call there will be a mismatch between the fingerprints stored
natively, and those in the settings database, and when merging the two
lists the new fingerprint will end up being removed from the native
storage.
