    sysctl - Add -i and -q from FreeBSD
    
    Enhance the sysctl code, will be used by /etc/network.subr
    
    * sysctl -i	- Exit cleanly with exit code 0 if a sysctl mib does not
    		  exist.  No warning or error message is output for this
    		  case.
    
    * sysctl -q	- Exit with exit code N if a sysctl mib does not exist.
    		  N is the number of mib's on the command line which failed.
    		  No warning or error message is output for this case.
