mesh-batadv-core: introduce 11s mesh, refactor wireless config

Browse Source 
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,
            },
    },

WLAN Configuration of your community in the 2.4Ghz radio. Consisting
of ``ssid`` of your client network, the ``channel`` your community is using,
``htmode``, the adhoc ssid ``mesh_ssid`` used between devices, the adhoc
bssid ``mesh_bssid`` and the adhoc multicast rate ``mesh_mcast_rate``.
Optionally ``mesh_vlan`` can be used to setup VLAN on top of the 802.11
ad-hoc interface. The options ``mesh_disabled`` and ``client_disabled``
are optional, too. They allow to disable the SSID by default, e.g. for
preconfigured node. This only affects first configuraton.
Combined in an dictionary, e.g.:
WLAN configuration for 2.4 GHz devices.
``channel`` must be set to a valid wireless channel for your radio.
``htmode`` selects the desired htmode (e.g. HT20, HT40- or HT40+).
There are currently three interface types available. You many choose to
configure any subset of them:
- ``ap`` creates a master interface where clients may connect
- ``mesh`` creates an 802.11s mesh interface with forwarding disabled
- ``ibss`` creates an ad-hoc interface
Each interface may be disabled by setting ``disabled`` to ``true``.
This will only affect new installations.
Upgrades will not changed the disabled state.
``ap`` requires a single parameter, a string, named ``ssid`` which sets the interface's ESSID.
``mesh`` requires a single parameter, a string, named ``id`` which sets the mesh id.
``ibss`` requires two parametersr: ``ssid`` (a string) and ``bssid`` (a MAC).
An optional parameter ``vlan`` (integer) is supported.
Both ``mesh`` and ``ibss`` accept an optional ``mcast_rate`` (kbit/s) parameter for setting the default multicast datarate.
