fixes for GCC 6: - -Wstrict-prototypes is not available for C++, so don't try to ignore it for C++. - remove many _DIAGASSERT() checks against not NULL for functions with arguments with nonnull attributes. in two cases, leave code behind that should set defaults to "(null)". - use -Wno-error=frame-address for i386 mcount, as it seems valid to assume the caller will have a frame.fair

__BEGIN_DECLS
Add __returns_twice for the attribute of the same name. This makes the attribute explicit based on the functions GCC gives it too.
