* Synchronization of zone reload and zone transfers.
* Fixed build on NetBSD 5 and FreeBSD.
* Fixed binding to both IPv4 and IPv6 at the same time on special
interfaces.
* Fixed access rights of created files.

wildcard in the same zone.
Other improvements:
* IXFR-in optimized.
* Many zones loading optimized.
* More detailed log messages (mostly transfer-related).

servers.

* Copying OPCODE and RD bit from query to NOTIMPL responses.
* Corrected response to CNAME queries if the canonical name was also
an alias (was adding the whole CNAME chain to the response).
* Fixed crash when NS or MX points to an alias.
* Fixed problem with early closing of filedescriptors (lead to crash
when compiling and loading or bootstrapping and restarting the server
with a lot of zones).
Other improvements:
* Significantly sped up IXFR-in and reduced its memory requirements.
