Add KeyStore.onUserPasswordChanged for the lockscreen to call when
the user changes their password. Keystore will then handle the logic of
deleting keys. Instead of calling Keystore.password_uid for both
unlocking and password changes the behavior has been split into
Keystore.unlock and onUserPasswordChanged.

This converts KM_ERROR_CALLER_NONCE_PROHIBITED into
InvalidAlgorithmParameterSpec, as expected by the contract of JCA
Cipher.

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.

This simplifies the AndroidKeyStore API around user authentication: no
more explicit control over which user authenticators are bound to
which keys.
User-authenticated keys with timeout are unlocked by whatever unlocks
the secure lock screen (currently, password/PIN/pattern or
fingerprint). User-authenticated keys that need authentication for
every use are unlocked by fingerprint only.

This updates the documentation of the application element of
AndroidManifest.xml to mention the new android:usesCleartextTraffic
attribute.
This also updates the Javadoc of
android.security.NetworkSecurityPolicy and ApplicationInfo to match.

This replaces int-based enums from KeyStoreKeyConstraints with
String values commonly used in JCA API.
As part of under the hood refactoring:
* KeyStoreKeyCharacteristics and KeyStoreKeyConstraints have been
merged into KeyStoreKeyProperties.
* KeymasterUtils methods operating on KeymasterArguments and
KeymasterCharacteristics have been moved to their respective
classes.

This makes the new AndroidKeyStore API conform with the latest
Keymaster API changes as well as the latest Android framework API
design guidelines.
Keymaster changes:
* Multiple paddings, block modes, and digests can be set on a key.
* "max uses per boot" and "min seconds between use" restrictions will
not be exposed in the framework API.
* Padding scheme ZERO will not be exposed.
Changes due to Android framework design guidelines:
* Sets of enum values have been replaced with bitsets represented as
ints.
* Integer has been replaced with int, with null being represented
with a special value (e.g., -1 or 0) where possible.

generateKey and begin can now optionally take an array of bytes to add
to the rng entropy of the device before the operation. If entropy is
specified and the device does not support add_rng_entropy or the call
fails then that device will not be used, leading to fallback or error
depending on the situation.

Now that the libcore's NetworkSecurityPolicy abstraction is in place,
the framework version of the abstraction should delegate to the
libcore one, to avoid them getting out of sync.

Having it as a raw byte[] caused issues in keystore because keymaster
handles a null blob differently than a blob with null contents. Make
this explicit in the API.
