    netstruct: Use the correct size for bounds checking in 'select'.
    
    Previously, it compared the size of the slice against
    the size of the field. Now it compares against the size
    of the whole structure, which should have been done in
    the first place.
    
    * gnu/gnunet/netstruct/procedural.scm
      (select): Perform size calculation on the whole netstructure,
      not only the field.
