This reverts commit 543eb178.

Restores the dns caching configuration that should be feasible, since we
now require around 8 MB of flash.

Add cellular configuration support to Gluon. This implementtaion focuses
not on hotpluggable WWAN adapters but instead on embedded LTE modems
found in travel-routers or FWA CPEs.

as well as the target itself

If the uci option 'gluon.wireless.preserve_channels' is set then the channel width of wireless radios (htmode) is preserved during updates, too.

Use the country3 option implemented in OpenWrt's hostapd configuration
handling instead of adding it as a custom option.

This method previously returned the string literal of the config key,
leading to checks evaluating to true even in case this option was
disabled.

The preserve_channels configuration option was moved to the gluon UCI
package without adding a proper migration.

Depending on the source of the primary MAC address, uppercase digits
would be used on some devices. Convert the address to lowercase for
consistency.

We only change the case for newly configured nodes to avoid changing the
node ID and derives MAC addresses for existing installations.

Only restore the netifd proto for the WAN bridge in case the upgrade is
done from an older Gluon version.

For DSL targets, OpenWrt defaults the WAN proto to pppoe, while Gluon
uses the Ethernet ports for WAN. When unconditionally preserving the WAN
proto, pppoe is carried over to Gluon's network config.

There was never a device with a dedicated WAN port supported in Gluon
which could make use of such a workaround.

As the only relevant lantiq-xrx200 target now uses swconfig anyways,
we can remove this workaround.

commit 071cf7b2 ("Switch to Lua for target definitions")

Has prior been introduced as untested -> broken in
commit d586720c ("ar71xx-generic: add support for Ubiquiti NanoBeam M5")

Was commented out in the former commit.

The new "value" helper can be used to turn a Lua value into a path that
can be passed to need_*() etc.

Removed in 45c84a11 ("ar71xx: drop target").

Instead of using roles.wan directly as the default for roles.single,
create a copy of the table, so subsequent modifications of roles.single
don't affect roles.wan as well.

Fixes migration of Mesh-on-WAN status when no default for "single"
interfaces is set in site.conf.

The function failed when an interface has no roles assigned, breaking
several upgrade scripts.

Closes #2471

Make the code match the docs and check_site.lua by actually looking up
the "default_roles" field, not "roles".

A section can be marked as preseved by setting the gluon_preserve option
to 1. In addition the following conditions must hold:

- The preserved section must not already exist after OpenWrt's and
  Gluons setup scripts run. Modifying existing sections is currently
  unsupported.
- Preserved sections must be named, so it can be detected whether a
  section conflicts with a preexisting one.

Allow interface names to change on updates to handle hwconfig -> DSA and
similar migrations.

On devices with only a single interface, a sysconfig single_ifname is
created instead of wan_ifname or lan_ifname to allow separate
configuration in site.conf.
