Embedded SPU elf patching

Browse source 
- PS3 games include both PPU and SPU code in their PPU executables, so to make patching games that make use of the same SPU libraries easier, we add a system to find and patch them.
- Patches for this system still use SPU LS (Local Storage) addresses despite the fact that we aren't loading anything into SPU LS at this time. The patches are checked against each segment and patched in place.
