Nit: Should use "_" not "__" (wunderbars are reserved)

I don't know where this magic number comes from.  Can you do the addition of
this file (and nacl_paths.cc) as a separate change so that it can be reviewed on
its own?  It's not really manageable for me to review changes like this in the
middle of such a huge changeset.

+  FILE_NACL_HELPER_BOOTSTRAP,    // ... and nacl_helper_bootstrap executable.

+  PATH_END

+// Call once to register the provider for the path keys defined above.
+void RegisterPathProvider();
