    ip_address: add str_address_reversed() et.al., simplify build_dns_name()
    
    In build_dns_name(), use fmt_address_reversed(), and strip trailing
    '.'s before formatting an FQDN (not after by scribbling over the
    output buffer).
    
    Revive tests and add them to ipcheck.
    
    Redefine ADDRTOT_BUF as sizeof(ip_address_reversed_buf).  Turns out
    that the old value (32 * 2 + 3 + 1 + 3 + 1 + 1) has always been one
    byte too small - the second "3" should have been "4" for "ARPA" (the
    things you find when running tests!?!).  Fortunately only client used
    a different and bigger constant.
