Import nsd-4.6.0; last import was nsd-4.3.5 23 June 2022: Wouter - Tag for 4.6.0rc1. It became 4.6.0 on 30 June 2022, and it continues with version 4.6.1. 17 June 2022: Wouter - Fix compilation with libev, without event_base_loopbreak. 16 June 2022: Wouter - Fix that the unit test verify_repat cleans up nsd on exit. - Fix to remove ixfrcreate.c asserts about uint16 within limits because of warnings from analyzers. 14 June 2022: Wouter - Fix compilation without libevent and compilation of nsd-mem. - Fix verify handler add of sigchld event for compilation without libevent. 3 June 2022: Wouter - Fix static analyzer reports on ixfrcreate temp file. - Fixup wrong ixfrcreate fread return check. 13 May 2022: Wouter - The code repo continues with version 4.5.1. 6 May 2022: Wouter - Merge PR #209: IXFR out This adds IXFR out functionality to NSD. NSD can copy IXFRs from upstream to downstream clients, or create IXFRs from zonefiles. The options store-ixfr: yes and create-ixfr: yes can be used to turn this on. Default is turned off. The options ixfr-number and ixfr-size can be used to tune the number of IXFR transfers and total data size stored. This is configured per zone, the IXFRs are served to the hosts that are allowed to perform zone transfers. And if TSIG is configured, signed with the same key. The content is stored to file if a zonefile is configured for the zone, in the zonefile.ixfr and zonefile.ixfr.2, .. files. They contain readable text format. The number of IXFRs is num.rixfr in statistics output, also per zone if per zone statistics are enabled. If offline, nsd-checkzone -i can create ixfr files. NSD already supports requesting IXFRs, this addition allows NSD to serve IXFR transfers to clients. NSD stops responding with NOTIMPL to IXFR requests, also for zones that do not have IXFR enabled. The clients gets a full zone reply or a status reply if the serial is up to date. - set version to 4.5.0 for feature change. - Tag for 4.5.0rc1 release.

Instead of preallocating all elements, they are allocated when used. There are options for managing the memory usage, defaults are the same as before. xfrd-tcp-max sets the number of sockets for tcp connections that xfrd can make to download zone contents.
