This commit mostly just moves code to a separate file, but it also includes a
couple changes:
Converts several critical messages to warnings. moves some data from RedWorker
to DisplayChannelClient (e.g. jpeg_data). As such, I think it's worth splitting
this into separate commits so that we can review more effictively. Will post
soon.
