[suggestion] Warning "Skipping obsolete configuration option" should suggest what the replacement is
I've encountered these two messages in the log:
Jul 24 22:39:01.908 [warn] Skipping obsolete configuration option 'DNSListenAddress'
Jul 24 22:39:01.909 [warn] Skipping obsolete configuration option 'TransListenAddress'
An obvious improvement for such messages is to suggest what they should be replaced with.
