rototiller: add threaded rendering
This is a simple worker thread implementation derived from the ray_threads code in the ray module. The ray_threads code should be discarded in a future commit now that rototiller can render fragments using threads. If a module supplies a prepare_frame() method, then it is called per-frame to prepare a rototiller_frame_t which specifies how to divvy up the page into fragments. Those fragments are then dispatched to a thread per CPU which call the module's rendering function in parallel. There is no coupling of the number of fragments in a frame to the number of threads/CPUs. Some modules may benefit from the locality of tile-based rendering, so the fragments are simply dispatched across the available CPUs in a striped fashion. Helpers will be added later to the fb interface for tiling fragments, which modules desiring tiled rendering may utilize in their prepare_frame() methods. This commit does not modify any modules to become threaded, it only adds the scaffolding.
