compile fixes for newer local_zones_lookup, unused variable warnings
fixed, and also manual page description of the feature.
- Merge #1087: Overload `local_data_remove` to support removing
specific records.
Here we overload the `local_data_remove` control command to support
deleting specific records. Curently, this command deletes all records
for a given zone. The modification works by attempting to parse the
command argument first as a complete record and then as just a domain
name, if the first attempt failed.
This preserves the command's behavior, while also supporting removing
specific records from the zone tree.

Found by the static analyzer Svace (ISP RAS).
After having been compared to a NULL value at worker.c:2216,
pointer 'worker->stat_timer' is passed in call to function
'worker_restart_timer' at worker.c:2319,where it is
dereferenced at worker.c:2029.
Fix that stat_timer creation failure in worker_init does
not continue with a NULL timer that causes a crash later.

In addition, the error replies do not contain parts of the
incoming query. This is more conformant, stops reflection
and stops it as a covert channel. Thanks to Yuqi Qiu and

In addition, thanks to Qifan Zhang, Palo Alto Networks, for
noting the fingerprinting possibility, that is also fixed
with this.
- Introduce new 'tls-protocols' configuration option that specifies
which of the supported TLS protocols will be used.
This change invalidates some previous changes:
- TLSv1.2 is again enabled by default, but can be selectively turned off if
desired (related to #1303).
- The biefly introduced (not yet released) 'tls-use-system-versions'
configuration option, that addressed #1346, is reverted in favor of
'tls-protocols'.
- The briefly introduced (not yet released) '--enable-system-tls'
configure option, related to #1401, is no longer needed with the new
option and the current default.
