George Koehler e04166b85d More prototypes, less register in mach/proto/ncg
Files that #include "equiv.h" must do so after including "data.h", now
that a function prototype in equiv.h uses type rl_p from data.h.

Adjust style, changing some `for(...)` to `for (...)`.  The style in
mach/proto/ncg is less than consistent; the big annoyance now is that
some files want tabs at 4 spaces, others want tabs at 8 spaces.
