Daniel Scheller 220354bc78 ddbridge/octonet: compile modules from object referenced in Kbuild 
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
