Bin protocol-token; respecify message-token.
Bin protocol-token; respecify message-token.

As explained on <https://bugs.freedesktop.org/show_bug.cgi?id=26838#c2>,
protocol-token has never been implemented, and it's impossible to
provide the uniqueness guarantees people might want for incoming
messages, so we shouldn't pretend otherwise. Since message-token is
already in use and implemented in a manner compliant with a weakening of
its uniqueness guarantees, I think respecifying it is safe.

(This would, however, break the N900's event logger, which does depend
on message-tokens being globally unique.)
