mod_imap patch

[Randy Terbush <ra...@zyzzyva.com>]

The following patch fixes the segmentation violation when
accessing an image map with a browser that does not 
understand ISMAP, and for those times when you forget to
add the tag. :^) A more comprehensive solution should be
forthcoming when the ability to add HTML attributes is
added. Should we be returning DECLINED instead?

Since we are still patching the release, I am including
patches to Makefile and Configuration to give some
evidence that this has been compiled on NetBSD.
