Roland C. Dowdeswell eb682c1bf4 Fix weight zero entries when ordering SRV RR results. ...

In lib/roken/resolve.c, we find rk_dns_srv_order() which re-orders
the results of an SRV RR lookup by the algorithm in RFC2782.  We
note that the algorithm doesn't behave according to the RFC w.r.t.
entries of weight zero.  We solve this by scaling out the remaining
weights by the number of zeros we find at a particular priority
level and acting like the zero weights have a weight of one.
