Fixes #961

Backport a few patches to allow sysupgrades on mmcblk and similar block
devices.

Fixes #975

This lifts batman-adv and alfred to version 2016.4.

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
with

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

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

The downgraded version of ath9k was reported to cause issues with Windows
clients before. Remove the problematic patch.

In addition, the temperature compensation support patch is reverted.

It seems that newer mac80211 version are less stable, so we downgrade it
for now.

This probably doesn't affect Gluon as nothing is using recvmmsg, but it's
still a good idea to get this fixed ASAP.

Generate flashable images for the Archer C7 v2 with current stock firmware
again.

To set the region code, the GLUON_REGION variable must be set to "us" or
"eu" in site.mk or as a make argument.

Fixes #860

Fixes #800

Includes a few security updates and enables Curve25519 support.

Fixes #223

This patchset enables the RX LNA for the CPE210/510, improving RX by about
20dB. The profiles for CPE210 and CPE510 is split into two images.

The problematic patch switching the CPE510 to the secondary ART is left
out.

Fixes #658

Caused by a broken backport.
