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, so the
CPE510 can use the correct ART offset, improving the TX power by 10dB.

Fixes #796

Now really fixes the build on Debian Jessie...

No sysupgrade support yet.

For some reason, the filenames of the OpenMesh support patches were
truncated.

Allow to build Gluon with GCC 4.7 (e.g. on Debian Wheezy) as host compiler
again.

Most doubles that are delivered via respondd have limited input
precision, but are converted with up to 17 digits of precision. That can
cause ugly blowups like 0.2800000000000001 in the output, which is
avoided by specifying better format strings (like "%.2f" in most cases).

The OpenMesh devices have a sticker with the eth0 mac address on the
bottom. Also all other mac addresses are calculated based on this address.
Therefore, it is better to use this as primary mac address instead of the
WiFi mac address.

The returned name for OpenMesh devices with a an extra vX when calling

    lua -e 'print(require("platform_info").get_image_name())'

doesn't contain a dash between the vX and the device name. Thus the image
should also not contain a dash.

The new ath9k/ath10k based devices are only available in OpenWrt trunk. The
relevant patches have to backported to add support for them in Gluon

The workaround to generate sysupgrade images for OpenMesh devices in gluon
is replaced in LEDE/OpenWrt by a special patch. It is therefore better to
drop the workaround and use the upstream version.

Don't fork reboot process before all package hooks have been handled and
rendering is complete.

Replace debug.setfenv hack to close stdout with nixio.dup.

Fixes #772

This was causing "recursive dependency" errors and potentially broken
configurations.

Integrate OpenMesh devices available in OpenWrt Chaos Calmer:

 - MR600
 - MR600v2
 - MR900
 - MR900v2
 - OM2P
 - OM2P-HS
 - OM2P-HSv2
 - OM2P-LC
 - OM2Pv2
 - OM5P
 - OM5P-AN

The image validation currently fails on some devices (tested OpenMesh)
because it isn't done via sysupgrade. But the checks depend partially on
the integration in sysupgrade (e.g. via loops that can be stopped via
"break statements").

Instead of hacking its own version check, it is easier and better tested to
just use 'sysupgrade -T' like it is already done by LuCI.

Fixes #764

Also backport some patches improving QCA956x support.

Lua's tables are 1-based, so we must decrement the index by 1 to get the
desired MAC addresses. By not doing this, the second IBSS interface would
get the address with index 8, but only indices 0..7 are available.

Make pkg-config, mkimage and gcc build with GCC 6 as host compiler. Fix
miscompilation of node.
