This release fixes the novel ghost domain issues CVE-2022-30698 and
CVE-2022-30699. They were reported by Xiang Li from the Network and
Information Security Lab of Tsinghua University.

Other than that there are some bug fixes, and an option to configure the
max retransmit timeout, infra-cache-max-rtt. If left at default it does
not make any change.

Because it is a security fix point release, there is no RC1 release 
candidate.

- Merge #718: Introduce infra-cache-max-rtt option to config max
   retransmit timeout.

   outbound tcp sockets.

- Fix dname count in sldns parse type descriptor for SVCB and HTTPS.
- For windows crosscompile, fix setting the IPV6_MTU socket option
   equivalent (IPV6_USER_MTU); allows cross compiling with latest
   cross-compiler versions.
- Merge PR 714: Avoid treat normal hosts as unresponsive servers.
   And fixup the lock code.
- iana portlist update.
