Networking work:
Split the networking stack into end-user library (libsocket) and two helper libraries (libnet and libnetif).
Don't use over-the-hand compiling and linking, but rather separation of conserns.
There might be still some issues and the non-modular networking architecture is currently broken, but this will be fixed soon.
