[tor-commits] [torsocks/osx] Remove socksdns, tordns and hostnames configure options.

commit a445ee509995cca33595647b37c290884944743f

    Remove socksdns, tordns and hostnames configure options.
    
    These options are defunct:
     1. socksdns (force dns lookups to use tcp)
        torsocks does this by default, no reason to make it optional.
     2. tordns (force dns lookups through tor)
        torsocks does this by default, option has been a no-op for a
        long time.
     3. hostnames (resolve name of socks server if required)
        potentially useful, but not really a good idea for tor.
