The next-node interface may be useful with IPv4 only or even just a MAC
address. This prepares merging gluon-next-node into gluon-batman-adv-core.

Because we unconditionally appended `-i br-client` to the command line of
respondd, it wasn't restarted when br-client changed state. Now, we use a
jsonfilter expression on the network.interface dump data, similar to how the
other interface names are generated, and only add the interface to the argument
list if it is up.

* use tabs instead of spaces
* use jsonfilter for speed

The  assignment of the gpio_count and reg_base in ath79_gpio_output_select
takes care that only supported platforms can use ath79_gpio_output_select.
But the rebase of the patches after the last OpenWrt base update
accidentally added an extra check for the SoC which was missing support
soc_is_qca955x().

Boots on QCA955X devices which were using ath79_gpio_output_select stopped

Fixes #941

Fixes: 212c38f0 "ar71xx: add model detection for UBNT Rocket Ti"

Some (possibly broken) bootloaders incorrectly initialize the at8033 phy.
This breaks auto-negotation on these SGMII devices. The mode has therefore
to be set back in to a valid configuration by Linux.

Fixes #911

The interfaces were accidentially switched when the CPE210 was separated
from the CPE510 code.

OpenWrt does this by default to save some space.

Don't use system /tmp for build.

propose to make uci commit more specific to minimize unwanted changes in other temporary written config files like wireless ssid (in some offline changers)

Fixes #897

Fixes the Ubiquiti UAP Outdoor+ HSR.

Using HTTPS breaks the download on Debian Wheezy. The switch was an
unintended side effect of the backport from LEDE.

Also, fix the commit message of the backport patch (mwlwifi is not updated
anymore since the last OpenWrt base upgrade).

Fixes #919
