If I have understood the RFC correctly, it talks about SRV RR and not A
RR, and as far as I know, there is no RFC updated 1034 and 952 on this
aspect.  The same thing worked for FreeBSD's portsnap service at the
very least, and also Yahoo's domain key, but neither is an A RR having
underscore and, for many traditional Internet applications like
sendmail, an A RR with underscore is rejected.

I have made a change on -CURRENT and is waiting for comments from others
to see if it's suitable for MFC, to make it possible to resolve an A RR
with underscore symbol, instead of querying it and drop the result, and
give the application an opportunity to choose between rejecting or
allowing _'s when they are using gethostbyname().
