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.
