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.

of server continues if a secondary zone fails to load.
Failed loads clear the zone data, so there is no partial
zone. Thanks to Qifan Zhang, Palo Alto Networks, for
the report.
limit auth-zone and rpz transfer amount and time taken.
Default is disabled. This hardens against unbounded
transfers. Thanks to Qifan Zhang, Palo Alto Networks,
for the report.
- 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.
- Review comment for checking out of memory condition

an overly large number of RRSIGs. It can be configured with
`iter-scrub-rrsig: 8`, it has default 8. Thanks to Yuxiao Wu,
Tsinghua University for the report.
- On fast_reload, the identity and version strings are always freed and
reallocated as part of dt_apply_cfg(). Add fr_worker_pickup_dnstap_changes()
to copy any changes from daemon to workers.
* Statistics counter for number of queries dropped by limit on reply addresses
Request list entries can be associated with multiple pending "reply
addresses". Basically each request list entry keeps its own list of
clients that should receive the response once the recursion is finished.
This requires keeping allocations around for each client, and there is
a global limit on the number of *additional* reply addresses that can
be allocated. (Each new request list entry seems to get its own initial
reply address which is not counted against the limit.)
This commit adds a statistics counter "num_queries_replyaddr_limit" that
counts the number of incoming client queries that have been dropped due
to the restriction on allocating additional reply addresses. This allows
distinguishing these drops from other kinds of drops.
* Statistics counter for number of mesh reply entries
Request list entries can be associated with multiple pending "reply
addresses". Since there is a limit on the number of additional reply
addresses that can be allocated which can cause incoming queries to be
dropped if exceeded, it would be nice to be able to track this number.
This commit basically exports the mesh_area's internal counter
`num_reply_addrs` as "threadX.requestlist.current.replies" /
"total.requestlist.current.replies".
* 'tls-use-system-policy-versions' is introduced to allow Unbound to use
any system available TLS version when serving TLS.
* Apply suggestions from code review
