Clean up CSTYLEDs

69 CSTYLED BEGINs remain, appx. 30 of which can be removed if cstyle(1)
had a useful policy regarding
  CALL(ARG1,
  	ARG2,
  	ARG3);
above 2 lines. As it stands, it spits out *both*
  sysctl_os.c: 385: continuation line should be indented by 4 spaces
  sysctl_os.c: 385: indent by spaces instead of tabs
which is very cool

Another >10 could be fixed by removing "ulong" &al. handling.
I don't foresee anyone actually using it intentionally
(does it even exist in modern headers? why did it in the first place?).
