ssl_set1_host() is not available without openssl-1.1.0. Unbound can not do
host cert verification. DNS over TLS connects, but hosts are unverified. A
patch for log err is added with a noitce in README.md.

Also, squash some minor robustness and TLS usability fixes.

Unbound struggles with boot ifup, so procd triggers changed to push
outside of this noise. Unbound has run in /var/lib/unbound/, so chroot
(jail) protects /etc/, and it can save flash wear. Compiled defaults
reflect this now, so Unbound tools are easier run on the command line.

With growing interest, DNS over TLS can be setup in Unbounds foward-zone:
clause. A broader UCI solution is added to support forward-, stub-, and
auth- zone clauses in a new 'zone' section. This implentation required
reworking scripts, because they did not scale. 'forward_domain' and
'prefetch_root' options are removed, and superceded by 'zone' section.

When UCI local zone is private and static, Unbound covered private
addresses with defaults. Optional delegated global IP6 prefix
protection lacked a static zone, but it was prevented from appearing
in global DNS responses. Domain names router-as-TLD, "lan." and
"local." were static, but they lacked default SOA or NS such as
Unbound had assinged to private addresses. Clean up these local
zones UCI evaluation and block global DNS inclusion.

Add the possibility to use Unbound auto-zone: clause to

A vulnerability was discovered in the processing of wildcard synthesized
NSEC records. While synthesis of NSEC records is allowed by RFC4592,
these synthesized owner names should not be used in the NSEC processing.
This does, however, happen in Unbound 1.6.7 and earlier versions.

When using the configuration under "Unbound and odhcpd" in the package's
README.md, the scripts generated a malformed config file for unbound, due
to an "ip route" command giving extra output lines with the string
"anycast" where the awk script expects an address. These are now filtered.

Build depends refer to source package names, not binary package names.
In many cases, PKG_BUILD_DEPENDS simply duplicated runtime dependencies of
a source package's binary packages; as the corresponding source packages
are implicitly added as bulid dependencies, PKG_BUILD_DEPENDS can simply be
dropped in these cases. In the other cases, *_BUILD_DEPENDS is fixed to
refer to the correct source package name.
Dependency of mysql-server is adjusted from libncursesw to libncurses
(as libncursesw is a virtual package provided by libncurses), so the build
dependency on ncurses is emitted unconditionally.

With this patch the unbound init routines manage resolv.conf if and only if

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.

adblock 2.3.0 file output is now detected and automatically

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:'

unbound-with-odhcpd have better/added UCI starters. HOW TO for
including unbound_srv.conf and unbound_ext.conf are added.
