Shawn Willden f0f05d4052 Add utility method to perform HMAC agreement
To make it easier for clients (vold & keystore) to perform key
agreement, this CL adds a service method that does it.  To make key
agreement consistent, this method sorts the HMAC sharing parameters
lexicographically.  The requirement for sorting is documented in the
HAL.
