Bjoern A. Zeeb 2bebb49117 Add size-guards evaluated at compile-time to the main struct vnet_* 
which are not in a module of their own like gif.

Single kernel compiles and universe will fail if the size of the struct
changes. Th expected values are given in sys/vimage.h.
See the comments where how to handle this.
