[PATCH 5/5] utimens: use extern-inline

[Paul Eggert]

* lib/utimens.c (_GL_UTIMENS_INLINE): Define when including utimens.h.
* lib/utimens.h: Add copyright notice, since this is now large enough
to copyright.  Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END.
(_GL_UTIMENS_INLINE): New macro.  Use it instead of 'static inline'.
* modules/utimens (Depends-on): Add extern-inline.
