build: fix inconsistent handling of BROKEN variable.

There are a few devices which have more than one LAN interface (for example
some revision of the TL-WR941ND, which uses a DSA-based switch, so each
switch port has its own netdev.) On these devices we need a bridge for
mesh-on-lan (as the alternative of adding them to batman-adv individually
would need too many MAC addresses.)

While ath9k/ath10k devices can supprt VIFs with any combination of MAC addresses, there are also adapters which have a hardware MAC filter which only allows a few bits to differ. This commit changes the addresses of all VIFs to ony differ in the last 3 bits, which is required to support many Ralink/Mediatek based WLAN adapters.

Technically, the new addresses are generated by calculating an MD5 hash of the primary MAC address and using a part of this hash as a prefix for the MAC addresses.

The addresses (BSSIDs) of the AP VIFs are also reused for the LAN and WAN interfaces in mesh-on-LAN/WAN mode to reduce the number of needed addresses, and thus reduce the chance of collisions. This is not a problem as the MAC addresses of the AP VIFs are never used except as BSSID, and thus not seen by routing protocols like batman-adv.

We have Git for history, there's no reason to keep old files that aren't

Add support for carambola 2 board

Device information can be found at:
http://www.8devices.com/products/carambola-2
https://wiki.openwrt.org/toh/8devices/carambola2

I only did some minimal testing of gluon on the carambola 2 development
board:

 - Config mode works
 - Connects to Wifi Mesh
 - Allows clients to connect

Notably, autoupgrade has not yet been tested.

Change to 010-primary-mac is necessary as the mac address printed
on the sticker is the one of eth0, not the wifi mac.

Preparations for Multicast Snooping Final

Newer versions of Sphinx would break lines at the colons.

Fixes #710.

link "packages" instead of "community repositories"

add link for rejected features to bottom link list

link "#gluon" to webirc

link the mentioned commit 2a93c580

OpenWRT now supports the CISCO Meraki enterprise class routers
MR12, MR16, MR62 and MR66. The fabric firmware demands the yearly
renewal of a support license.

This firmware was successfully tested by @Garunda for the MR62 (and
the MR12 with it for which this is an alias). The initial firmware
pre OpenWRT adoption was prepared and adapted for Gluon by @tcatm.
The confirmation of the functionality of the image for the MR66
(and the aliased MR16 with it) is still pending.

The devices are of strategic interest to the Freifunk community as
they are making a rock-solid impression. However, these come with
fairly hefty annual license. The Freifunk may offer an escape route
for those who had signed up and want to keep their investment into the
similarly expensive hardware. Used evices sell for $60 on eBay/Amazon
in the US. Here in the old world it is all >300 €, still.

Credits go to @Garunda for testing, to @tcatm for finding the
OpenWRT patch prior to its adoption and preparing the initial Gluon
adaptation, to @smoe for the update once that patch had arrived in
OpenWRT, and to @NeoRaider for his review and advice to use
GluonModelAlias for MR62 and MR66 to point to MR12 and MR16,
respectively.

Avoid commiting configs inbetween to decrease number of flash writes.

Fixes #714.

It doesn't seem like this mistake had any effect.

Leads to broken symlink setup by OpenWrt, usually breaking the build with
a "Too many levels of symbolic links" message.

Fixes #716.
