Let's create a new file for this instead of adding it to ring_buffer.h.
Although it's being used by remote buffers, I rather not make this
something that people may think they can access anywhere.

Perhaps: ring_buffer_types.h

with a comment stating that these are to be used by the remote ring buffers
and the ring buffer internals and should not be used directly.
