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.

Original commit message:

    MIPS: ath79: make bootconsole wait for both THRE and TEMT

    This makes the ath79 bootconsole behave the same way as the generic 8250
    bootconsole.

    Also waiting for TEMT (transmit buffer is empty) instead of just THRE
    (transmit buffer is not full) ensures that all characters have been
    transmitted before the real serial driver starts reconfiguring the serial
    controller (which would sometimes result in garbage being transmitted.)
    This change does not cause a visible performance loss.

    In addition, this seems to fix a hang observed in certain configurations on
    many AR7xxx/AR9xxx SoCs during autoconfig of the real serial driver.

    A more complete follow-up patch will disable 8250 autoconfig for ath79
    altogether (the serial controller is detected as a 16550A, which is not
    fully compatible with the ath79 serial, and the autoconfig may lead to
    undefined behavior on ath79.)

Fixes some messages if /bin/sh doesn't support 'echo -e'.

docs: add 2016 copyright year to sphinx conf file

Patch tested on v2016.1.x branch with Freifunk Magdeburg firmware on
Debian Jessie amd64 Xen host. See the same patch in our gluon fork here:
https://github.com/FreifunkMD/gluon/blob/fix-sysupgrade-xen/patches/openwrt/0058-x86-fix-platform_export_bootpart-for-Xen-virtual-disks.patch



Sysupgrade was tested successfully by manually making the change before
upgrading in the filesystem of the running node and upgrading to the
fixed FFMD experimental build in config mode via expert settings in
webgui.

Patch also submitted to OpenWRT trunk already.

Add Support for the ALFA Hornet UB and similar devices

The Hornet UB is sold at least in the varieties. Without case it is a Hornet UB, with case and without connected USB port it is called AP121. If the USB port is present this device is called AP121U.
We have a AP121U in our mesh http://meshviewer.chemnitz.freifunk.net/#!v:m;n:00c0ca6efffa

Preparations for Multicast Snooping

docs: fix typo in upgrade.rst

Add support for TP-Link TL-WA7510N

This CPE is supported by OpenWRT and already running in Chemnitz

This include wasn't actually missing, but well hidden behind the iwinfo.h
include. Make this more obvious.

Adopt the according modifications to the default firewall settings of
the WAN interface from OpenWRT, revision 45613.

An IGMP/MLD domain split will prevent us from being able to track
multicast listeners on other nodes.

Therefore we need to always hand any multicast packets we received from
local clients to batman-adv. With bridge multicast snooping disabled,
the current setting in Gluon, this is already the case.

However, in preparation to enabling multicast snooping, we need to
enforce forwarding towards batman-adv by setting the bridge port
option "multicast_router" to 2.
