    kernel - Silently accept any value for IPV6_V6ONLY sockopt
    
    * Numerous utilities including named behave horribly if the IPV6_V6ONLY
      socketopt returns a failure.  We were returning failure if anyone
      attempted to set it to 0.
    
    * just silently ignore the value entirely, always return success.  Fixes
      named, libuv (which named uses), and numerous other ports that use
      libuv or otherwise stupidly mess with this socketopt.
