This is a site.conf-breaking change in regard to the wireless config.
Make sure to read http://gluon.readthedocs.org/en/latest/user/site.html
and update your site.conf accordingly!

Support for 802.11s mesh interfaces has been added. Gluon now supports
three interface types: ap, ibss and mesh. All of them are now optional
and may be configured independently in site.conf.

A sample site.conf may look like this:

    wifi24 = {
            channel = 1,
            htmode = 'HT40+',
            ap = {
                    ssid = 'luebeck.freifunk.net',
            },
            ibss = {
                    ssid = '02:d1:11:37:fc:38',
                    bssid = '02:d1:11:37:fc:38',
                    mcast_rate = 12000,
            },
            mesh = {
                    id = 'ffhl-mesh',
                    mcast_rate = 12000,
            },
    },

Using service_start requires exporting of environment variables.

Fixes #397

The nodeinfo/network/addresses announcement included deprecated and
tentative addresses, which it clearly shouldn't as the host doesn't want
to be contacted on those addresses. They are now filtered out.

This was broken due to the switch to Chaos Calmer.

This fixes MAC address conflicts on devices which use the eth0 as primary
address.

This should fix the signal strength indicators on the TP-Link CPE210/510.

These targets don't have a WLAN adapter by default, so it doesn't make
sense to default to the phy0 address.

error() is a glibc specific function and should not be used in
code meant to be portable.

This limits the number of concurrent users to 2 or 3 (approx. 4 connections per
user), greatly reducing DoS potential.

Always output empty objects or nothing at all where objects are expected, but
no elements exist.

Also remove a few unneeded "requires", a few basic modules are provided by
announce.lua by default.

Export Mode -> Expert Mode

15 is the default in batman-adv-legacy, the new default 30 in newer batman-adv
versions is too high in larger networks.

fixes #365

By introducing a new option -a in addition to -p this patch allows
controlling the on-link flag of announcements.

A prefix specified using -a will have the on-link flag set to zero
while a prefix specified using -p will retain its behaviour (i.e.
on-link flag set).

Example:

    gluon-radvd -i local-node -p 2001:db8:aaaa:/64 -a 2001:db8:bbbb::/64

This will announce 2001:db8:aaaa::/64 with the on-link flag set and
2001:db8:bbbb::/64 with the flag unset.

This adds mesh_on_lan functionality.

A new optional site.conf option, mesh_on_lan, has been added. If set to
'true', all LAN ports will be used for meshing instead of being part of
the client bridge.

This will introduce a new nodeinfo object, network.mesh.bat0.interfaces,
containing any of the the following subordinated objects:

- wireless
- tunnel
- other

Each of these objects contains a (possibly empty) list of MAC addresses
(lowercase, colon-notation) corresponding to a interface of the given
class. Combined with a batman graph it is thus possible to mark
sub-graphs as "wireless" or "vpn".

The previously used object mesh_intefaces is superseded by this new
object structure and mesh_interfaces will be removed in a future Gluon
release.

Directly using libiwinfo is more reliable.

It would be nice to generalize this to work with multiple radios, maybe by
integrating it into the wifi-config module...

Fixes #219

This new package allows enabling or disabling the null method for the
fastd mesh VPN.

This new class allows visually pleasing lists of radio buttons/checkboxes/etc.
with long explanation texts.

All other titles are grey, the magenta-colored section titles inbetween look
weird.
