Priviously we installed the legacy keystore SPI by the name
KeyStore.AndroidKeyStore and set an alias to
KeyStore.AndroidKeyStoreLegacy. This conflicted with with the Keystore
provider which also registers as KeyStore.AndroidKeyStore.
This patch registers the old provider only by the name
KeyStore.AndroidKeyStore.

Test: None
Change-Id: I3db72c17a9cb999a0248df4c37588dfc2ad84f74

With this patch we install the old Keystore provider as
AndroidKeyStoreLegacy when the Keystore 2.0 provider is installed as
AndroidKeyStore. This allows system components to keep using the old
keystore while we can run CTS tests against the new provider.

The tests are still mostly failing at this point. Installing the new SPI
can be enabled by setting the property
ro.android.security.keystore2.enable=true

We no longer need to get the key characteristics from the Keystore

key info from the KeyParameter AIDL type rather than from the hand
written KeymasterArguments.

This patch also exposes the correct security level for a key through
KeyInfo.

This patch evolves the Crypto SPI to use the new Keystore 2.0 shim.
The main changes are:
 * The SPI uses the AIDL defined KeyParameter instead of
   KeymasterArguments.
 * Operations are created directly from the KeystoreSecurityLevel that
   is part of the AndroidKeyStoreKey object.

Also this patch deletes the DeletatingX509Certificate class. This is no
longer needed, because public key operations are no longer performed by
Keystore 2.0. We can delegate public certificate operations simply by
wrapping such certificates into public keys that are understood by other
providers, such as BouncyCastle.

The wire type for key parameters is now generated from AIDL rather than
the hand written parcelable KeymasterArguments. So we need some of the
utilities for creating key parameters that the latter provided.
We also nicked some utility function from KeymasterUtils.

This patch makes the chunked streamer observe the simplified
Keystore 2.0 operation interface. Keystore is now required to consume
all supplied data or reject data outright if too much (more than 32KiB)
is supplied in a single transaction. This allows for a simplified
streamer logic and a simplified interface. We also no longer send
entropy to Keystore. This will be handled by the Keystore 2.0 daemon.

Keystore 2.0 does no longer report an error code if an operation
requires user authorization. Instead this is indicated by sending us
an operation challenge. In that case we have to check if the
authorization can possibly succeed. We changed the utility class by
adding a predicate function that checks exactly that, and we handle
other errors separately instead of having one exception handling path
that does all.

KeyStoreKeys can now be constructed from key entry metadata and key
descriptors as defined by the new Keystore AIDL spec.
AndroidKeystorePublicKey can now create the private key proxy.
KeyStoreKeys also cache the key characteristic, which should drastically
reduce the frequency by which the SPI has to call into the Keystore 2.0
daemon.

This patch adds a shim around the Keystore 2.0 AIDL spec. The new shim
is modularized like the AIDL spec into the base Keystore module
Keystore2, the security level specific interface KeystoreSecurityLevel,
and the operation specific interface KeystoreOperation.

Other system maintenance specific interfaces have yet to be added.

This patch copies the relevant portion of the Keystore SPI to the new
package name android.security.keystore2. The purpose of this is to
illustrate the evolution from the existing Keystore SPI to the
Keystore 2.0 SPI while keeping the existing Keystore SPI intact.
Reviewers are advised to check the equivalence of this code to the
corresponding files in
    android/security/keystore (<-- no 2 here).
Subsequent patches can them be reviewed as evolution towards the new SPI
rather than completely new code.

Test: None. When the evolution is complete, Keystore CTS tests can be
used to check for regressions.

A normal synchronous binder call would not be influenced by an
interrupted thread. With the move to asynchronous keystore IPC we wait
on a future which can throw an interrupted exception. The Java crypto
API does not expect the implementation to throw interrupted exceptions
though. So to preserve the expected behavior we wrap the Future.get()
calls in a loop that handles the interrupted exception and sets the
interrupted state after the get completed successfully.

Update keyguard locked state from TrustManagerService

TrustManagerService holds the ground truth about whether a user is
locked or not, so update keystore using the information there,
instead of doing it from KeyguardStateMonitor. This fixes the issue
of work profile locked state not being correctly pushed to keystore.

Note: since this change is likely to be backported as a security
patch, I'm refraining from doing major refactoring right now.
