Upon further thought, this patch is somewhat unwieldy. I intent to
split it up. I plan to split it into the following:
1. Fixing the settimeofday64 weirdness
2. 1:1 move from lsm_hooks.h to lsm_hook_types.h of the hook
definitions (union + comments)
3. Rewiring lsm_hooks.h to use macros only
4. Rewiring security.h to use macros only

Does that sound reasonable?
