Add a framework for subtitle decoder modules that work more like audio/video decoders do, and change libass rendering of demuxed subtitles to use the new framework. The old subtitle code is messy, with details specific to handling particular subtitle types spread over high-level code. This should make it easier to clean things up and fix some bugs/limitations.
