    y2038: include: Move struct __timeval64 definition to a separate file
    
    The struct __timeval64's definition has been moved from ./include/time.h to
    ./include/struct___timeval64.h.
    
    This change would prevent from polluting other glibc namespaces (when
    headers are modified to support 64 bit time on architectures with
    __WORDSIZE==32).
    
    Now it is possible to just include definition of this particular structure
    when needed.
