With a backported patch from the OpenWrt trunk, it is now easy to generate an
equivalent configuration using CONFIG_ALL_KMODS.

The build will take a bit longer because all kernel module packages are actually
built even when they are not included in the image, but adding new targets
becomes a lot easier.

Also, related documentation updates and fixes.

This reverts commit 59ea630e.

This shouldn't affect compatiblity with kernel modules and will allow us to
find out under which hypervisor we're running.

No autoupdater support yet, but that will follow.

Includes a profile for the NETGEAR WNDR3700v4 and WNDR4300v1

Added TLWR743

Built, flashed and successully tested. This patch takes advantage of patch freifunk-gluon@e93173c which solved issue freifunk-gluon#226 by introducing "GluonProfileFactorySuffix". Packages are separated by a space, not a comma. The ALL0315N initially has a OpenWRT based firmware and there is no need for a factory image. The sysupgrade can be flashed instantly.

x86-generic is still marked as broken as fastd v16 doesn't work with uClibc on
x86. This will be fixed with fastd v17.
