This moves the non-public API classes backing Android Keystore from
android.security to android.security.keystore, a package specially
created for Android Keystore.

This enables users of AndroidKeyStore crypto to differentiate between
the key being unusable until the user is authenticated
(UserNotAuthenticatedException) and the key being permanently unusable
(KeyPermanentlyInvalidatedException). The latter is the case when the
secure lock screen has been disabled or reset, and, for keys that
require user authentication for every use, when a new fingerprint is
enrolled or all fingerprints are unenrolled.
NOTE: The KeyPermanentlyInvalidatedException subsumes/replaces the
NewFingerprintEnrolledException which has thus been removed. There
is no way to find out whether a key was permenently invalidated
specifically because a new fingerprint was added.

When AndroidKeyStore keys require used authentication, they need to be
bound to a Keymaster's Secure User ID. This ID will be set by keystore
soon. Until then, set it from the framework level (i.e., from apps
which use AndroidKeyStore).
NOTE: Accessing gatekeeper to obtain the Secure User ID will be
blocked by SELinux policy. To test this code, disable SELinux
enforcing mode.
