devfs.conf support for wildcarded devices

I saw a previous post once on this, but I haven't seen support for
wildcards implemented.  I've gone ahead and tried what I think is a
workable mechanism to support this.  Please let me know if this would do
what I think people are interested in (it does what I want ;)
