unbound version is 1.12.0

1. notice: init module 1: subnet
   Having a config-module: "subnet ..."
   results in an error. The correct configuration is, probably,
   config-module: "subnetcache ..."
   Is that correct?
   With config-module: "subnetcache ..."
   the log have:

   unbound[3228]: [3228:0] notice: init module 1: subnet

   I think the name in the log should match exactly the name in
   unbound -V, and in the configuration.

2. See the list of linked modules with unbound -h
   Sometimes, when there is a reference to a module that is not present, the comment in the log is:

   ... This module is not present (not compiled in), See the list of linked modules with unbound -h

   Was that meant to be unbound -V?
