    y2038: inet: Convert inet deadline to support 64 bit time
    
    This change brings 64 bit time support to inet deadline related code for
    architectures with __WORDSIZE == 32 && __TIMESIZE != 64.
    
    It is also safe to replace struct timespec with struct __timespec64 in
    deadline related structures as:
    
    - The __deadline_to_ms () returns the number of miliseconds to deadline to
      be used with __poll (and hence it is a relative value).
    - To calculate the deadline from timeval (which will be converted latter)
      the uintmax_t type is used (unsinged long long int).
