Keymaster HAL currently requires that key validity start and end dates
always be specified. The framework API does not. This CL expresses
the framework API's "not specified" instants to Keymaster as instants
in distant past or future.

This also adds the MAC length constraint on imported HMAC keys. HMAC
doesn't work without this constraint at the moment.

AES and HmacSHA256 symmetric keys can now be imported into
AndroidKeyStore. These keys cannot yet be used.

Add the encrypted flag for the KeyPairGenerator and the KeyStore so that
applications can choose to allow entries when there is no lockscreen.

In previous commits, we added the ability to specify which UID we want to
target on certain operations. This commit adds the ability to reach those
binder calls from the KeyStore class.
Also fix a problem where saw() was not reading all the values returned via
the Binder call. This changes the semantics to return a null instead of
failing silently when it's not possible to search.

Existing KeyStore implementations throw NullPointerExceptions beacuse
the KeyStoreSpi doesn't check these arguments for null. Add in checks so
we don't accidentally check some bogus values.
Also switch a RuntimeException to a KeyStoreException

For the AndroidKeyStore API, allow entries to have their certificate
chain replaced without destroying the underlying PrivateKey. Since
entries are backed by unexportable private keys, requiring them to be
supplied again doesn't make sense and is impossible.

This allows end-users to generate keys in the keystore without the
private part of the key ever needing to leave the device. The generation
process also generates a self-signed certificate.

This introduces a public API for the Android keystore that is accessible
via java.security.KeyStore API. This allows programs to store
PrivateKeyEntry and TrustedCertificateEntry items visible only to
themselves.
Future work should include:
* Implement KeyStore.CallbackHandlerProtection parameter to allow the
caller to request that the keystore daemon unlock itself via the
system password input dialog.
* Implement SecretKeyEntry once that support is in keystore daemon
