[Suggestion] video code refactor

[eezstreet]

I suggest we refactor the video code to be in rd-common, and load different formats other than .ROQ for the cinematics. The idea is that the video loader would operate similar to the way the image code is done, with something like:

static const videoLoader_t [] = {
    {"roq", OpenROQ, StreamROQ, CloseROQ},
    {"mpeg", OpenMPEG, StreamMPEG, CloseMPEG},
    {"mov", OpenMP4, StreamMP4, CloseMP4},
    {"avi", OpenAVI, StreamAVI, CloseAVI},
};

I realize that most of these formats are container formats, so I suggest we use libavcodec, which is LGPL (compatible with GPLv2/3, yes?)

I'm an idiot, this code is really handled by the client and not the renderer.

But in a surprising twist of fate, libavcodec supports ROQ format, so we can just use that and replace all the ROQ code wholesale, while gaining support for all those other formats in the list.
