This feels weird to reference ppapi::proxy at all here... this should use a
different namespace, I think.

Would it make sense to instead declare these somewhere in ppapi/nacl_irt? I'm
not clear yet on what that directory is for.

I intended ppapi/nacl_irt/ to be used just for public headers that define NaCl's
stable ABI, not for anything else.  So it's similar to ppapi/c/.
