clean up some deprecated/obsolete options and doc (!7506) · Merge requests · ISC Open Source Projects / BIND · GitLab

Evan Hunt requested to merge 3780-deprecated-obsolete-cleanup into main Feb 08, 2023

removed documentation of -S option from named man page
removed documentation of reserved-sockets from ARM
simplified documentation of dnssec-secure-to-insecure - it now just says it's obsolete rather than describing what it doesn't do anymore
marked three formerly obsolete options as ancient: parent-registration-delay, reserved-sockets, and suppress-initial-notify

Closes #3780 (closed)
