Fixes the main-thread hitch reported on Dolphin (and, less severely, elsewhere) whenever the MP3 decode buffer needed refilling: audioStreamMp3Read() -> audioStreamMp3DecoderDecodeFrame() does real work synchronously (asset I/O + libmad decode), previously called directly from each platform's once-per-frame Feed(), blocking rendering for a frame on every refill. Adds a background decode-ahead ring (src/duskmad/audiostreammp3ring.c): a one-shot-per-pass thread reads via the existing audioStreamRead() into a ring buffer ahead of need; Feed() becomes a cheap, lock-protected drain instead of a decode call. Reuses this project's own thread_t/threadmutex_t (mutex+condvar) primitives, mirroring PSP's own background-thread-plus-ring precedent. Fixes a real (if narrow) race in thread.c along the way: threadHandler() reset thread->threadId outside the mutex it also used to signal STOPPED, which a stop-then-immediately-restart pattern (needed once per pass: play/seek/loop-restart) could hit as a stale-threadId assertion. Initially built Dolphin-only, then generalized: the ring doesn't touch ASND at all, so it was straightforward to share with Linux too, moving both it and the libmad decoder into a new top-level src/duskmad/ - a shared-capability directory in the same vein as src/duskgl or src/dusknetwork, pulled in by whichever DUSK_TARGET_SYSTEM values need it (linux/knulli, wii/gamecube) rather than PSP, which keeps its own hardware sceMp3 decoder and ring untouched. With both platforms now sharing real code, deduped what was left: audioStreamComputeEndFrame() (loop-segment math, byte-identical between Linux/Dolphin) moved to the generic audio/stream/audiostream.c, and audioStreamMp3Ring*IfNeeded()/audioStreamReadForPlayback() wrappers (in duskmad) collapse each platform's own `if(stream->type == AUDIO_STREAM_TYPE_MP3)` branches at every Init/Dispose/Buffer/Feed call site into one check each, living in the ring module itself.
