Description changed by david:

New description:
http://httpd.apache.org/docs/2.2/mod/core.html#servertokens allows
changing the version info string. We need at least the Minor setting; we
will very likely need the Min[imal] setting in the future.
If people have a configuration where the directive is incorrect, the
result may be messed up handling of incoming URLs in the routing, as Agavi
needs to apply certain hacks depending on how miserable exactly the Apache
version is. This is super hard to debug, and even harder to put into docs,
or a WTF document or anything, because it's a very fuzzy error situation.
So instead, we should throw an exception, asking people to
* fix their http.conf, or
* override SERVER_SOFTWARE with a static value in factories.xml (that
should be possible, obviously), or
* force a value for SERVER_SOFTWARE in index.php
