description:
PosixDaemon.c: restore NetBSD logging additions lost in merges

Restore part of local modifications r. 1.2 & 1.4 from tsarna@. One
aspect could not be carried forward, as Apple dropped the bug detection
query functionality that was formerly represented by the teststate
member of the DNSServer struct. Otherwise, reapplied almost verbatim,
except for minor consistency and style changes.

This was added again in part as an example should there be a need to
add further logging content for NetBSD's purposes. (DumpStateLog() has
changed further as of Apple's 1790.80.10 release, but should we roll
forward, our means here should still be viable.)
