u64: use extern-inline

* lib/u64.c: New file.
* lib/u64.h: Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END.
(_GL_U64_INLINE): New macro.  Use it instead of 'static inline'.
* modules/u64 (Files): Add lib/u64.c.
(Depends-on): Add extern-inline.
(configure.ac): No need to require AC_C_INLINE, since extern-inline
does that now.
(lib_SOURCES): Add u64.c.
