DNS flag day 2020, software should reflect the minimum EDNS 1232 bytes.
Added iface_wan and iface_lan to control internal DNS assignemnts and
to control what is local service ACL. Interface wild cards are not
explicitly set so that they can be customized in extended conf.

The two unique packages "Unbound light" and "Unbound heavy"
were not working well due to the fact that Unbound is mostly
its library. Tools and helpers would crash. Instead a reasonable
default Unbound is built. Also up select options like python
are added. libevent and libpthreads are options to down select.

Unbound has a quirk and may reply on a different device address.
When Unbound answers with from-address different than it
received queries on, it may cause trouble for select VPN and
firewall configurations. Ensure Unbound replies with the same
address by changing this default.

This exposes the interface-auto option to UCI.
By default, interface-auto is disabled.
This leads to the DNS reply possibly originating from
a different address then the request was sent to.
Devices with a packet filter might not receive the reply in this case.
Enabling interface-auto ensures the reply is sent with the
source-address the request was sent to.

This patch enables ipset support in the unbound-daemon-heavy variant. See [1] for
instructions on how to use it.
Also fix a minor typo in the libunbound-light description.

This removes lines that set PKG_BUILD_DIR when the set value is no
different from the default value.
Specifically, the line is removed if the assigned value is:
* $(BUILD_DIR)/$(PKG_NAME)-$(BUILD_VARIANT)/$(PKG_NAME)-$(PKG_VERSION)
The default PKG_BUILD_DIR was updated[1] to incorporate BUILD_VARIANT
if it is set, so now this is identical to the default value.
* $(BUILD_DIR)/$(PKG_NAME)-$(BUILD_VARIANT)/$(PKG_SOURCE_SUBDIR)
if PKG_SOURCE_SUBDIR is set to $(PKG_NAME)-$(PKG_VERSION), making it
the same as the previous case
* $(BUILD_DIR)/$(PKG_NAME)-$(PKG_VERSION)
This is the same as the default PKG_BUILD_DIR when there is no
BUILD_VARIANT.
* $(BUILD_DIR)/[name]-$(PKG_VERSION)
where [name] is a string that is identical to PKG_NAME

- treat RFC6762 'local.' as nxdomain because avahi and other services
will disable if SOA or NS records appear in central DNS.
- allow two threads to be enabled with the 'heavy traffic' variant of
Unbound packages.

Two seperate package names were chosen instead of menu selected options
because dependents need a ready (large) package in release directory.

Expressions '-o', '-a', and '\( \)' within test or '[ ]' are obsolete.
POSIX allows few arguments to test, so long expressions are not
portable. '[ p -a q ]' can be replaced with '[ p ] && [ q ]' instead.

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.

Unbound UCI so far has limited forward configuration lacking
DNS over TLS connection setup tools. User override files
'unbound_srv.conf' and 'unbound_ext.conf' can implement this.
