* Changed the way the socket functions work:

Browse Source 
- The net_stack driver is no longer used. Instead we have a kernel
    module which is directly used by syscall implementations in the
    kernel. I.e. we no longer tunnel those functions through ioctls, but
    have normal syscalls.
  - Removed the superfluous net starter module.
  - Implemented the FDTYPE_SOCKET type file_descriptors, that is sockets
    are no longer vnode based.
  - Adjusted libnetwork (the socket function implementations)
    accordingly.
  - Adjusted netstat accordingly.
* Socket module:
  - Implemented socketpair().
  - Added "kernel" parameter to the control hook. Quite a few more hooks
    would actually need the parameter, but I didn't change those yet,
    since that would probably also require changes to the protocol
    module interface.
