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.
(see: https://www.nlnetlabs.nl/bugs-script/show_bug.cgi?id=658)
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'prefetch_root' options are removed, and superceded by 'zone' section.

- Add domain_forward to permit designated domains to forward instead
of recurse as listed in resolve.conf.auto from DHCP WAN client
- Update rebind_protection and add rebind_interface to protect IP6
GLA locally just like RFC 1918 protection
- Rename trigger to trigger_interface with backwards compatability
- Update odhcpd script for efficiency handling many clients

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.

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

Until now unbound was always running as root by default. A DNS resolver can
easily run under a non-privileged user.

This is an import of the net/unbound package from Subversion
revision 40658 (May 2, 2014). The only change is the addition of
PKG_LICENSE, PKG_LICENSE_FILE and PKG_MAINTAINER to Makefile.
Unbound 1.4.22 is the current upstream release.
