must not *skip* obsolete options.

Tor version 0.3.5.8 ignores DNSListenAddress.

While it logs May 21 08:59:58 raven Tor-transparent[32235]: Skipping obsolete configuration option 'TransListenAddress' May 21 08:59:58 raven Tor-transparent[32235]: Skipping obsolete configuration option 'DNSListenAddress'

it still starts, and then binds to 127.0.0.1:53, breaking all sorts of things.

If it finds obsolete configuration options, it really, really, really must not ignore then and do unwanted stuff.
