End the process after one result in case -l is not given

Reduces singleshot execution time from timeout seconds to around 150ms.

resolves #2184

No package uses l2tp_ip.

This device is a dual 5GHz device. It is recommended to manually change the
radio of the first device to the lower 5GHz channels and the second radio
to the upper 5GHz channels

Fixes warnings about implicit pointer-to-int and int-to-pointer casts.

Fixes: 59a4cd63 ("gluon-respondd: expose OWE clients in nodeinfo")

Fixes respondd on 64bit archs, as gluonutil_get_primary_domain() was
assumed to return int without the prototype.

Fixes: bcf57467 ("libgluonutil: implement gluonutil_get_primary_domain()")

This adds the OpenWrt label-mac device selection as the most preferred
fallback.

While this is only used on OpenWrt 19.07 for backports, we can also use
the label-mac device when backporting device support. This way, we have
to deal with less device-sepcific code downstream.

This commit introduces a simple function for writing to the syslog and
replaces the custom function used by gluon-hoodselector.

This switches the used wireless daemons for OWE / SAE to the OpenSSL
flavors. The WolfSSL implementation currently seems to be broken.

THis switch may be reverted at a later point in time when hostapd /
wpa_supplicant implementations for WolfSSL have matured.

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.

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.
