    rc.d/sysctl: Rewrite to be more robust and clean
    
    * Check the validity of the sysctl config and warn about the invalid
      syntax.
    
      A common mistake is that users set 'sysctl <mib>=<val>' in
      /etc/sysctl.conf, which generate huge amount of junk/mysterious
      messages on the console.  Now this will be warned.
    
    * Reorganize the logic to be much cleaner.
    
    * Do not bother to check whether the new value is different from the old
      one.
    
    * Rename the function for consistency.
