Define IN_HISTORICAL_NETS for kernel space

    kernel: deprecate Internet Class A/B/C

    Hide historical Class A/B/C macros unless IN_HISTORICAL_NETS is defined;
    define it for user level.  Define IN_MULTICAST separately from IN_CLASSD,
    and use it in pf instead of IN_CLASSD.  Stop using class for setting
    default masks when not specified; instead, define new default mask
    (24 bits).  Warn when an Internet address is set without a mask.
