Both devices differ by a additional power outlet for the EX3800.
This patch has been tested on a EX3800 device.

* gluon-core: remove obsolete file 100-core-reset-sysctl

* gluon-core: remove obsolete cleanup line

* gluon-client-bridge: remove obsolete cleanup line

This renames the local_client zone to loc_client, as local_clint exceeds
the maximum zone length allowed for firewall3, which is 11 bytes.

This worked previously due to firewall3 using unsafe string operations.
Now creation of the chain fails (latest OpenWrt master).

This allows running a respondd querier and map server behind a Gluon
node.

For instance at Freifunk Lübeck we now moved the map server
behind a Gluon VM and removed batman-adv and fastd from the
map server VM to reduce the maintenance work.

Increased multicast overhead should be minimal / non existent, as it is
unlikely to accidentally have respondd queriers running behind a Gluon
node.

The rewrite of the feature handling introduced multiple major bugs. One
of them was caused by the way Lua's logical operators work:

An expression of the form

    _'autoupdater' and _'web-advanced'

would return 'web-advanced' rather than the boolean true when _ returned
both strings unchanged (because the features are enabled).

As entries with more than a single feature name in their expressions did
not set no_default, Gluon would then attempt to add gluon-web-advanced to
the package selection, as web-advanced is a "pure" feature.

To fix this, and get rid of the annoying nodefault, separate handling of
"pure" feature and handling of logical expressions into two separate
functions, called feature() and when(). To simplify the feature
definitions, the package list is now passed directly to these functions
rather than in a table with a single field 'packages'.

Default to the alphabetically smallest branch if none is set in
site.conf.

Also prevent enabling the autoupdater when no branches exist.

The new options are CONFIG_GLUON_AUTOUPDATER_BRANCH and
CONFIG_GLUON_AUTOUPDATER_ENABLED and allow to control the default branch
and default enable status separately.

The `or ''` fallback in targets/generic is removed, as GLUON_ENV will
set all variables in GLUON_VARS, making previously non-existing
variables exist with an empty value.

We already have a proper message when the creation of an alias fails
because of a name conflict. Also add a message when the primary filename
of a domain config is already occupied by another domain's alias.

Also add an 'Error:' prefix to the existing message to easier to see.

Reorder scripts so that the mesh_lan interface is accounted for.

Two other firewall upgrade scripts (mesh-babel and l3roamd) are
reordered as well. While there seems to be no hard dependency at the
moment, it makes sense to run the basic setup first, also to avoid
problems with future changes.

Closes: #2090

This adds the wireless client count for 2.4GHz and 5 GHz radios to the
status page. Previously, only the total client count advertised by
the mesh protocol was visible.

This will hide the outdoor mode setting on compatible devices in case
the defined channels should be preserved.

Otherwise a user might be under the impression their device is compliant
with outdoor operation when in reality it still uses prohibited
channels.

Allow replacing the default OSM layer with a custom XYZ layer in

Replace the ugly arrow shown in Firefox with a custom SVG arrow. Tested
and working in Firefox, Chrome and Edge. The arrow doesn't show in IE, but
the gluon-web-model JavaScript is already severely broken in IE, so we
don't care.

Remove unused and obsolete code.

The `features` file is converted to a Lua-based DSL.

A helper function `_` is used in the DSL; this will return the original
string for enabled features, and nil for disabled features. This allows
to use boolean operations on features without making the code too
verbose.

Besides having more readable and robust code, this also fixes the bug
that all files `packages/*/features` were evaluated instead of only
using the feature definitions of currently active feeds.

This script is an implementation detail - let's not clutter the global
$PATH namespace with a script with such a generic name.

When gluon.core.switch_domain is set, it replaces the old domain.

This also replaces an unnecessary uci:commit() with uci:save().

The package rebuild logic of OpenWrt only checks regular files. Avoid
symlinks in the files directory to make rebuilds more robust.

This commit changes the behavior for the wan-dnsmasq to read the
interfaces to update the DNS servers on from flag-files.

This way, external custom packages which add a custom VPN WAN interface
can update the DNS server gluon is using for WAN resolving.

On lantiq, the default WAN ifname is 'dsl0' even on devices that have a
separate WAN port. At least on devices using swconfig we can override
this with the switch port labelled as 'wan'.

Backporting the MFP patch allows us to utilize WPA3 features on this
target.

Tested on TP-Link Archer C20i

Instead of looking at the initial UCI config, we can read this
information from board.json.

With very bad timing, it is possible that the teardown script of a
gluon_mesh interface runs when bat0 was just created, but primary0 is not
yet added to it. Although there is no hardif to remove in this case,
bat0 will still be deleted, because there is no hardif in bat0.

Disable the interface removal logic by passing `-M` to `batctl interface`.
