Separate wireless-related helper methods from the util module to a
new wireless module. This keeps them separated, as the amount of
wireless helpers increased in the past, justifying a separate module.

xt_CT was added to kmod-ipt-conntrack a while back. Update our
GLUON_SPECIALIZE_KERNEL rules accordingly.

When building xt_CT into the kernel, one of the symbols IP_NF_RAW and
IP6_NF_RAW must be enabled as well, even though there is no runtime
dependency when building as modules. The kernel grows by less than 1KB
even when both IP_NF_RAW and NETFILTER_XT_TARGET_CT are enabled, making
this change a (very slight) net win in both flash and RAM usage.

In OpenWrt 19.07, the block size was increased to 1024KiB for "tiny"
devices by default to save flash. Unfortunately, this also significantly
increases the cache memory required by squashfs.

In my test, the increased block size reduced the image size by ~64KiB,
but increased the RAM usage by ~2.6MiB. As most tiny devices have only
32MiB of RAM, this is not a reasonable tradeoff.

The ar71xx-generic target already defines an even lower block size of
64KiB.

This is unused by Gluon.

Closes #1974

Situation:
==========

$ ls -l /lib/gluon/domains/lindennord.json
lrwxrwxrwx    1 root     root            10 Jan  6 03:42 /lib/gluon/domains/lindennord.json -> dom17.json

Before:
=======

$ gluon-neighbour-info -d ::1 -p 1001 -r nodeinfo -c 1
{
   "node_id": "525400123456",
   "system": {
     "domain_code": "lindennord",
     "site_code": "ffh"
   },
...
}

After:
======

$ gluon-neighbour-info -d ::1 -p 1001 -r nodeinfo -c 1
{
   "node_id": "525400123456",
   "system": {
     "primary_domain_code": "dom17",
     "domain_code": "lindennord",
     "site_code": "ffh"
   },
...
}

Implemented using readlink() and basename() to the selected domain in
/lib/gluon/domains/${DOMAIN}.json.

Add x86-legacy subtarget

As x86-generic is compiled to pentium4 (and newer) there is a need for
a subtarget for older devices. The x86-legacy subtarget is set to
compile to pentium (and newer) and should support even very old devics.

x86-legacy includes the packages from x86.inc to only maintain one
package list. The three excludes are because the packages do not exist
for x86-legacy.

- Rely on shebang instead of setting shell in workflow
- Run whole install-dependencies.sh in sudo
- Use /bin/sh instead of bash
- set -e

The new step is added with `if: ${{ !cancelled() }}`, so the logs are
stored even when the build fails.

build: ignore deactivated feeds

Reuse outdoor device logic for setup mode interface selection, plus some cleanup

The OpenWrt feeds.conf.defaults contains some feeds that are commented out
and not active. Such feeds will be returned by the default_feeds.sh script
anyway and causing pseudo feeds. Limit the script to only return active
feeds, by filtering out lines starting with '#'.
This usually only applies to the OpenWrt master branch.

change as per NeoRider

As a partial fix to #496, do not touch the MAC address of the WAN
interface when using VXLANs (as only the MAC address of the VXLAN
interface matters to batman-adv).

This reverts commit 2a8943e5.

.SILENT gets passed down to OpenWrt make as -s through MAKEFLAGS. This
hides certain messages from the build log with V=s.

Certain error message (for example invalid package names) were emitted
once for each device.

gluon-mesh-vpn-fastd: clean up peers and groups on update

config_ifname was renamed to setup_ifname in Gluon v2015.1.

On PoE-powered devices, we usually want to use WAN for the setup mode.
As all outdoor devices are PoE-powered, we can reuse this function. This
switches the setup mode interface for new installations / after config
reset on a few devices that were missing in this list before.

- Use util.find_phy()
- Stop foreach() as soon as the result is known

The 'preserve' flag can be used to mark a peer so it is not removed or
modified on upgrades. In addition, groups containing preserved peers are
not removed.
