Enhance the 'control' option to allow using SSL
to connect to the server. Add the 'extended_stats'
option to match 'extended-statistics: yes.'
Document the 'extended_luci' option; it does not
control Unbound, but changes the LuCI tabs.

With this patch the unbound init routines manage resolv.conf if and only if
when unbound will listen on 127.0.0.1#53 and dnsmasq is not.
Also logs some cases where config values are overriden with sane defaults.
Fixes (partially) LEDE FS#785
Fixes openwrt/packages#4487

Base LEDE/OpenWrt UCI for dnsmasq provides for DNS override in
/etc/config/dhcp. It is desired to be able to use dnsmasq and
Unbound as transparently as possible. Option 'add_extra_dns'
will pull 'domain', 'mxhost', 'srvhost, and 'cname' from base.
netifd/procd have an interaction with DHCPv6/RA on WAN (FS#713).
Minor IP6 parameter updates can cause Unbound reload events every
few minutes. List option 'trigger' selects which interfaces may
cause reload. For example 'lan', 'wan' but not 'wan6'.
Squash other cosmetics.

procd interface triggers may be busy. Unbound hard restarts will
flush the cache. This might happen frequently depending on how
interface triggers occur.
Change the procd trigger to reduce occurences. Load this trigger
prior to netifd (START=20), but only truly start Unbound from
the trigger rather than immediately in init. Clean up log entries
in scripts after Unbound, NTP, and DNSSEC are established.

Unbound is configured to restart on hotplug/iface but this can result
in numerous restarts at boot. Unbound also has a restart for NTP.
This was observed to generate trouble and even with procd robustness
too many crashes might occur (rare). Unbound would not be running.
Give more care to /var/lib/unbound/root.key during restarts. Use procd
for iface restarts. Check pidof() to wait one more second for Unbound.

options 'add_local_fqdn' and 'add_wan_fqdn' can be affected
by race conditions when they are at level 4. Interface name
may not be returned by network tools. The conf file has bad
record formats and Unbound just will not load. Detect this
and fall back to only the host FQDN (level 3).
squash: improve documentation wording and format codes.

Unbound UCI tries to protect embedded flash from excess
use. Unbound RFC5011 KSK tracking can rewrite root.key
every few minutes to an hour. It also writes and destroys
files in the same directory during the process.
Recommended UCI delays for copying busy work in /var/
back to /etc/ may be too conservative. These are all
changed from 28 to 9 days.
The RFC5011 KSK results were also destroyed by an
init.d restart, even if /var/ is mounted on persistent
storage like USB drive. /var/lib/unbound/root.key is
now preserved during this process, unless a newer key
is installed in /etc/ manually or package update.

When for example 'package/net/adblock' and DNSSEC vs NTP robustness
is enabled, significant restart thrashing can occur at boot up. DHCP
lease triggers may be occuring at the same time. Unbounds DNS-DHCP
may be incomplete until new DHCP solicit events. Solve this by
leaving a passive but complete host conf file during lease trigger.

Bug fix dhcp4_slaac6 option was adding to all IP6 routes.
Filtering was added to this process to only include addresses
served from "this dhcp interface."
adblock 2.3.0 file output is now detected and automatically
integrated into Unbound local-zones. adblock deposites its
block site zone-files into /var/lib/unbound. If this is not
desired, then disable adblock or reconfigure to avoid Unbound.

Unbound+DHCP (server of your choice) should be able to replicate
a lot of what dnsmasq provides. With this change set Unbound
still works with dnsmasq, but also it can work with a plain
DHCP server. Features have been added within the UCI itself
to act like dnsmasq.
- alone: name each interface relative to router hostname
- alone: prevent upstream leakage of your domain and '.local'
- dnsmasq: use dnsmasq UCI to configure forwarding clauses
- dhcp: work with odhcpd as example of companion DHCP-DNS
- dhcp: convert DHCPv4 leases into EUI64 SLAAC for DNS records
- all: enable encrypted remote unbound-control using splice conf
- all: allow user spliced conf-files for hybrid UCI and manual conf
-- 'unbound_srv.conf' will be spliced into the 'server:' clause
-- 'unbound_ext.conf' will add clauses to the end, example 'forward:'
README HOW TO for dnsmasq-in-serial, dnsmasq-in-parallel, and
unbound-with-odhcpd have better/added UCI starters. HOW TO for
including unbound_srv.conf and unbound_ext.conf are added.
Document new UCI: add_local_fqdn, add_wan_fqdn, dhcp4_slaac6,
dhcp_link, domain, and domain_type

This is bare minimum change in 'unbound.sh' and
'dnsmasq.sh' to migrate the UCI option set for
more flexibility. The boolean(s) to link to
dnsmasq are being changed to a state to include
odhcpd. It is executable but a small step for
clear change management.

- History: prior to package 1.5.10-3 /var/lib/unbound was not used
- History: prior to package 1.5.10-4 no UCI scripts were provided
- Problem: UCI 'option manual_conf 1' only copied unbound.conf and root.key
- Problem: power users that had complex file nests cannot use this
- Fix: README.md includes instructions for /var/lib/unbound jail
- Fix: unbound.sh copies ALL of /etc/unbound for 'option manual_conf 1'
