gluon-autoupdater: revert to default branch when configured branch is invalid
An invalid branch may be set for various reasons:

- Previous firmware had an invalid default branch
- Branch list has changed and old UCI branch config was removed by a
  site-specific upgrade script
- Manual UCI configuration

7c81897b4c gluon-mesh-vpn-*: make vpn MTU provider specific
If a community uses different vpn providers, they typically
assume the same MTU for the wan device underneath the VPN. As
different VPN providers however have different overhead, the MTU
of the VPN device differs for each provider. Therefore this
commit makes the MTU of the VPN device provider specific.

This has two advantages:
1. The same site.conf can used to bake firmwares for different
   VPN providers (only by selecting a diferent vpn feature in the
   site.mk).
2. We are coming closer to the option of integrating multiple VPN
   providers into one firmware.

gluon-core: preserve explicitly marked network and system sections
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

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.

treewide: use interface roles as basis for network configuration
With the new role-based interface configuration, it would be better to
rename the wan/wan6 interfaces to uplink/uplink6, but that would cause
unnecessary churn for the firewall configuration, so it is left for a
later update.

As all interfaces with the 'uplink' role are in the br-wan bridge, it is
not possible to assign these to the 'mesh' role independently - instead,
br-wan is added as a mesh interface as soon as a single interface has
both the 'uplink' and 'mesh' roles. The UCI section for this
configuration is now called 'mesh_uplink' instead of 'mesh_wan'.

For all interfaces that have the 'mesh', but not the 'uplink' role a
second configuration 'mesh_other' is created. If there is more than one
such interface, all these interfaces are bridged as well (creating a
bridge 'br-mesh_other'). This replaces the 'mesh_lan' section with its
optional 'br-mesh_lan' bridge, but can also include interfaces that were
not considered "LAN" when interfaces roles are modified (via site.conf
or manually).

gluon-core: initialize interfaces role configuration
The new configuration generates sections iface_single/lan/wan in
/etc/config/gluon. These sections usually refer to a sysconfig-controlled
interface list, but adding custom sections with verbatim interfaces names
is also possible.

Each interface section contains a list of roles. The supported roles are
'client', 'uplink' and 'mesh'. Multiple roles can be configured on the
same interface (for example the old 'mesh_on_wan' setting would become
'uplink'+'mesh').

'client' is subsumed by any other role configured on the same interface
('client'+'mesh' is equivalent to 'mesh'). This property is important, as
it allows the Wired Mesh settings in gluon-web-network to simply add and
remove the mesh role without having to care what other roles are set -
so in the default setup, this would switch between 'client' and
'client'+'mesh' for the LAN interface.

By default, the WAN interface has role 'uplink' and the LAN interface
'client'; if only a single interface exists, the roles from the WAN
interface are used by default. The default for each of the three
interfaces (WAN/LAN/single) can be changed separated in site.conf,
superseding the old mesh_on_wan, mesh_on_lan and single_as_lan settings.

gluon-core: remove obsolete sysconfig.gluon_version handling
The file /lib/gluon/version/core hasn't existed since early 2014, so
this whole script is obsolete.

gluon-ebtables-limit-arp: declare clock as extern (#2343)
Declare the clock variable as extern in the header file.

Fixes compilation of gluon-ebtables-limit-arp with OpenWrt master:

multiple definition of `clock'; /gluon/openwrt/tmp/ccuynR0G.o:(.bss+0x230): first defined here

gluon-core: migrate wireless configuration from hwmode to band
The migration is done very early, as other upgrade scripts depend on the
band setting through platform.device_uses_11a().

treewide: use radio band option to determine frequency band
The 'hwmode' setting has been replaced with 'band' in OpenWrt to add
support for newer bands outside of 2.4G and 5G. Adjust Gluon accordingly.

gluon-ebtables-filter-ra-dhcp: disable DHCPv4 filter when gw_mode == 'server' (#2324)
In meshes without VPN or supernodes, it may be desirable to connect a
router providing IPv4 addresses directly to a regular Gluon node. For
this to work, it was necessary to remove the gluon-ebtables-filter-ra-dhcp
package from the node, so the autoupdater also needed to be disabled.

To avoid this, make gluon-ebtables-filter-ra-dhcp disable the DHCPv4
filter rules when gw_mode is set to 'server'.

No solution is provided for RA/DHCPv6, but this seems less pressing for
local meshes, as nodes can already provide working IPv6 connectivity
by themselves through gluon-radvd.

gluon-status-page: use UCI + iwinfo to get channel information
The network.wireless status ubus call only returns the configured
channel from UCI, breaking the status page in outdoor mode, where the
configuration contains 'auto' instead of a number.

8c85be2125 gluon-status-page: fix address_to_groups()
In js `return` does behave like `continue` in a forEach() iteration.
The fixed function was intended to return nothing on error and does so
now, instead of a shorter (useless) array like before.

gluon-neighbour-info: avoid recv() with NULL buffer (#2323)
Calling functions like recv() with a NULL buffer is not explicitly
allowed by the POSIX standard, so it must be avoided to be portable
across different libc implementations. Allocate an initial buffer before
handling requests, and also pass this buffer to the peek recv() call.

f419db58a2 Set PKG_VERSION in gluon.mk
This removes PKG_VERSION and PKG_RELEASE from most Makefiles, as the
value was never useful for Gluon packages; instead, PKG_VERSION is set
to 1 in gluon.mk.

It also removes two other weird definitions:

- gluon-iptables-clamp-mss-to-pmtu replicating the old PKG_VERSION logic
  from gluon-core, but without the fixed PKG_BUILD_DIR to prevent
  unnessary rebuilds
- gluon-hoodselector set GLUON_VERSION=3

gluon-core, gluon-site: get version numbers from .config
Calling git describe directly breaks isolation between the build system
and packages. Replace this with proper .config variables, like we
already do for GLUON_RELEASE.

Also replace the PKG_VERSION hack with a static '1', as we do for other
packages - while having those version numbers in opkg was cute, it was
also entirely useless. Having a fixed PKG_VERSION allows us to remove
the PKG_BUILD_DIR override as well.

gluon-neighbour-info: fix broken output with large results (#2322)
Currently a buffer with a fixed size of 8192 bytes is used. However the
result can potentially be larger, which leads to a truncated JSON
output on stdout. UDP packets, without compression and with IP
fragmentation, can be up to 64KiB large.

Instead of using a fixed size buffer on the stack ask the kernel first
about the size of the UDP data and allocate a buffer of appropriate size
on the heap before receiving the UDP data.

The issue was observed with a custom respondd provider.

gluon-mesh-vpn-wireguard: add package (#2168)
The address of the vpn interface is calculated in the style of
modified EUI-64, based on a virtual mac address. This virtual mac
address consists of 0x00 as first byte and the other five bytes
are taken from the first bytes of md5sum(base64 encoded public key).

The algorithm was taken by the ffmuc, with a slight difference. ffmuc
calculated the result of md5sum(base64 encoded public key + '\n')
which was interpreted as accidential fault and therefore dropped.

Example:
- Public-Key: "gP3VJnTTvnQut+z4O+m0N9RgMyXbgyUbUkF3E3TKX2w="
- Address: "fe80::02ca:b8ff:fedc:2eb3"

The following interfaces are used for wireguard:
- wg_mesh  -> wireguard interface
- mesh-vpn -> vxlan iface on top of wg_mesh

If you use this new feature, make sure the NTP servers in your site
config are publicly reachable. This is necessary, since wireguard
requires correct time before the vpn connection is established.
Therefore gluon performs ntp time synchronisation via WAN before it
establishes the vpn connection. Therefore the NTP servers have to
be publicly reachable (and not only via mesh).
