This adds MD5, SHA-1, SHA-224, SHA-384, and SHA-512. SHA-256 was
already there.
MD5 is not exposed for HMAC on purpose, because MD5 has been
deprecated for years.

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).

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).

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