Description

messages.proto has to be slightly changed to use a raw bytestream instead of a string for AuthenticationStartMessage as non CRAM-MD5 authentication mechanisms may transmit binary data.

NOTE that the above change does basically have no impact on C++ based proto code other than the prevention of a warning due to non-UTF8 characters being encoded.

Even though the above is pretty much determining that we wont run into compatibility issues (old master vs. new slave and vice versa), it still should be tested briefly.
