Kevin Chyn 749799387e Tweaks to fingerprint AIDL 
1) Explicit numbering for Error enum, which contains intentionally
   skipped entries for backwards compatibility
2) Documentation for vendorCode. The vendorCodes must have a well
   defined behavior with the array API for things like GSI to work,
   e.g. generic system image with non-generic HAL implementation -
   with this explicit requirement, both components, as long as the
   contract is followed, would allow proper string feedback to be
   loaded/shown.

Biometric HALs

Overview:

The interfaces within the biometrics.* HAL tree are used by the Android Biometric Services (e.g. FingerprintService, FaceService) to discover and operate biometric sensors on the device.

More details and versioning information can be found within each particular HAL.

More complete information about the Android Biometric HALs and subsystem can be found at source.android.com.
