This release fixes a bug where zone transfers would not succeed, because
of an error in the selective NSEC3 allocation (introduced in 4.1.18).
The refuse ANY query feature now sends truncated answers over UDP and
allows TCP queries. This is the same size response on UDP as the
refusal but allows the query to succeed over TCP for genuine queriers
that fallback to that transport mechanism.
The release contains a speed up for TCP processing that should NSD
better at handling large numbers of incoming TCP connections.
