If a type99 SPF record is found, don't even start looking for TXT.

I wish it were that simple.  Too many (braindead) DNS servers timeout
when presented with a type99 query.  The obvious algorithm of checking
type99 first, then check TXT if not found is unworkable thanks to these
antisocial beasts.

It might be useful to keep a cache of which DNS servers are braindead
(timeout on type99).
