qmpfw: Quick Mesh Project legacy firmware generator (deprecated)

Adds a new way to generate/store the configuration files for each target:
There are profiles (such as ath-qmp-small-node) which are shared between all similar kind of devices (i.e ubiquiti devices)
And individual configurations (optional) which can be used to specify extra options for the device

Adds support for new special target "ar71xx" which compiles the firmware for all atheros AR7/9 devices.

Adds new target for t-mr3040 bmx6 testing

Add new target for TpLink MR3040 with WebCam/Streaming support

Only diffconfig is stored now (not all the config)
Adapt the configs to new bmx6/luci-app-bmx6

Remove fonera and wispstation (not tested and probably not working)
Rebuild pico2 config file

Change name tl-wr703 for tl-703n
Rebuild 703n config file
