rototiller,fb: swap dispatch with page flipping
For the sake of sdl_fb, move page flipping into the main thread and run module render dispatch from another thread instead. This eliminates the fb flipper thread, moving its functionality into fb_flip() which synchronously consumes and performs a single flip from the same queue as before - the function is verbatim the loop body of the flipper thread. Now main() calls fb_flip() in a loop where it previously dispatched pages for rendering. Rendering dispatch is now performed in a created thread. See the comment in fb.c for more explanation of this shuffle.
