Revise most services to follow these guidelines:

- 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
