Add flash0:/kd/mpeg.prx to the sceUtility module swap, hung off av_mpegbase, so it loads when DisableHLEFlags::sceMpeg is set. Games that ship their own sceMpeg_library on the disc never get here and just use theirs. The piece that was missing to make it work: the access unit address mpeg.prx passes to sceVideocodecDecode is in Media Engine space, which we can't read. On hardware sceMpegBasePESpacketCopy DMA'd the payload there first. That copy is ours, so it now gathers the blocks and sceVideocodec decodes from those, falling back to main memory for any caller that points at it directly. The gather is keyed by destination, because that call carries the audio payload too - video to an ME address, audio to main memory - and handing an ATRAC packet to the H.264 decoder gets you nothing. With that, video/mpeg/basic gets a 144x80 frame out of real Sony code driving our sceVideocodec through ffmpeg. The test still fails overall, as it did before this branch - it is in tests_next.
