I think Roland recommended to having this in irt.h, but I'm not sure where he
was imagining this would sit in.  Perhaps inlined into irt_interfaces.cpp?

The other CL also seems to rely on these two having the same prefix, and have
connected version numbers (if you bump one, you must bump the other).  That
seems worth commenting, if that's what we go for.

Done.

 struct nacl_irt_ppapihook {
   int (*ppapi_start)(const struct PP_StartFunctions *);
   void (*ppapi_register_thread_creator)(const struct PP_ThreadFunctions *);
