This changes building ddbridge.ko and octonet.ko from including multiple C files right from the source code to building all of them separately into their own objects, and build the actual kernel module from these objects. Accomplished by: - rename of ddbridge.c to ddbridge-main.c and octonet. to octonet-main.c - rename of ddbridge-mod.c to ddbridge-modulator.c - add all C files to Kbuild and prepare Kbuild for this way of building the modules - add all neccessary annotations and includes
