bugfix for virtualhosts

[Alexei Kosut <ak...@organic.com>]

Recently, there've been some bug reports concering the interaction between
the Listen directives and Host:-header handling and related issues.

I've been able to track down this bug, which stems from the fact that the
Host-header checking code was assuming that all the virtual hosts were on
the same port as the main server, which isn't neccessarily true anymore
(since you can do <VirtualHost host:port>).

Here's a patch. I'd like to see it committed prior to a b4 or final
release of Apache 1.1.0, so if people could look it over, that'd be great.

Thanks!
