Take the <HostAlias> functionality added earlier, and fold it back

into <VirtualHost>. This hopefully makes for a config file that makes
more sense, plus it allows for easier transition, since the conf files
do not have to be changed. A ServerAlias directive has been added,
which goes inside the <VirtualHost> and can provide additional names
which that host will recognize itself as. These can include wildcards,
e.g. "ServerAlias *.foo.com foo.bar.net foo.com". The canonical name
is given by the <VirtualHost> directive or a ServerName.
