I think it is best to get rid of string2.h given it is only included in a limited number of
cases. There are now only small number of inlines left that are useful. The
explicit_bzero is an example of something you want to inline always (as it's just
memset), not in the limited cases of string2.h.

Yes if that's more appropriate. Does your header cleanup solve both the internal
name space issues as well as allowing builtins to be used in GLIBC internally?
