Thanks to Stefan Karlsson for helping with the implementation. Also add SASLMechanism.checkIfSuccessfulOrThrow(), to increase the security by verifying the mechanisms state at the end of SASL authentication. SASLMechanism now has a SASLPrep StringTransformer. Refactor SHA1 functions out of StringUtils into SHA1 utility class. Add MAC utility class. Make DummyConnection getSentpacket() methods use generics to make unit testing SCRAM-SHA1 easier. Fixes SMACK-398
