- Each service must have xyzInit/xyzExit (with that name)
- xyzInit/xyzExit use reference counting
- xyzExit returns void
- The utilities in <3ds/result.h> are used instead of manual error checking
- The intrinsics in <3ds/synchronization.h> are used instead of inline asm
- Other miscellaneous changes
- APT now uses a lightweight lock instead of a mutex
- Initial handle parameters in PTMU were killed
- Explicit init'ion to 0 or NULL has been removed for global variables
since they end up on .bss anyway
- MIC hasn't been touched because it must be rewritten first
- CFGNOR needs a slight touch before converting
- SOC is still to be cleaned up
