Changes with Apache 2.0.23-dev

  *) Add a handler to mod_includes.c.  This handler is designed to

     implement the XbitHack directive.  This can't be done with a

     fixup, because we need to check the content-type, which is

     only available in the handler phase.  [Ryan Bloom]

  *) Make the includes filter check return codes from filters lower in

     the filter chain.  If a lower level filter returns an error, then

     the request needs to stop immediately.  This allows mod_include to

    {NULL}
