b4834ae3fa Rename KeymasterException to KeyStoreException. 
The code in question talks to KeyStore which returns error codes
which are a mix of keystore and keymaster error codes. To better
match the layering of KeyStore on top of keystore and keymaster,
this CL renames KeymasterException into KeyStoreException. It also
adds human-readable error messages to exceptions raised by keystore
rather than keymaster (e.g., key not found).

a80eee052d Improve the AndroidKeyStore-backed HMAC state machine. 
This defers the start of a new KeyStore operation after Mac.doFinal
until the next Mac.update or .doFinal. Previously, the a new KeyStore
operation was started immediately, at the end of doFinal.

This adds AndroidKeyStore.getKeyStoreOperationHandle method which can
be used to obtain the KeyStore operation handle corresponding to the
provided JCA cryto primitive (provided it's backed by
AndroidKeyStore).
