SWCODEC/IRAM: Save voice IRAM when a plugin initializes its IRAM. Defines two macros for declaring and initializing IRAM. Plugins should use these instead. See mp3_encoder, doom, etc. for details. Further tweaks in buffer restoration after other use. Hiding of some interfaces that should only be used by buffer management.
