The objects RedsStream and RedsSASL are currently using the namespace "Reds" rather than the standard "Red" namespace used throughout the rest of the project. Change these to be consistent. This also means changing method names and some related enumeration types. The files were also renamed to reflect the change: reds-stream.[ch] -> red-stream.[ch] Signed-off-by: Jonathon Jongsma <jjongsma@redhat.com> Acked-by: Frediano Ziglio <fziglio@redhat.com>
