Unbound + Dnscrypt-proxy issue after upgrade to 23.7.x

[karlson2k]

After upgrade to 23.7.1_3 the Unbound daemon failed to stop without any errors in logs.

I'm using combination of Unbound + Dnscrypt-proxy and for this reason I have custom Unfound configuration file. 23.7 introduced changes in ACL handling and has small bug in configuration file.

As a workaround I used duplicated "server:" clause in custom configuration file. See here: https://forum.opnsense.org/index.php?topic=10670.msg172282#msg172282 It solved problem with starting Unbound.

The proper fix is submitted via PR on GitHub: https://github.com/opnsense/core/pull/6756

The initial steps were not obvious because no error is recorded in logs, while command `configctl unbound check` clearly indicated errors in config file. It is possible to record such errors in the log?
