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.

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
