don't know what i was smoking when I wrote log_request() like that...

Listening by default on all the addresses is so bad I don't know why I haven't changed this before. Anyway. Add a `listen on $hostname port $port' syntax to the config file and deprecate the old "port" and "ipv6" global setting. Still try to honour them when no "listen on" directive is used for backward compatibily, but this will go away in the next next version hopefully. At the moment the `listen on' in server context don't filter the host, i.e. one can still reach a host from a address not specified in the corresponding `liste on', this will be added later.

it fails bandly at runtime on various linux distros and on freebsd. Until a fix is found, disable it so I can move forward.

while here also make them a list rather than a fixed-size array.
