      X neo/protogen: Catch length checks overflows on decode · c884bfd5
      Kirill Smelkov authored
      For example a list is encoded as
      
      	l        u32
      	[l]item  itemType
      
      on decode len is read from data stream and for rest of data len(data) is
      checked to be < l*sizeof(item).
      
      However since l is u32 and sizeof(item) is just number the result of `l
      * sizeof(item)` has also u32 type. However it could overflow e.g. for
      
      	l		= 0x20000000
      	sizeof(item)	= 8
      
      with the l*sizeof(item) being = u32(0)	(exactly zero) -> oops.
      
      Avoid the problem by doing all checking arithmetics with u64 ints.
