buffer: don't allow growing borrowed buffers When we don't own a buffer (asize=0) we currently allow the usage of grow to copy the memory into a buffer we do own. This muddles the meaning of grow, and lets us be a bit cavalier with ownership semantics. Don't allow this any more. Usage of grow should be restricted to buffers which we know own their own memory. If unsure, we must not attempt to modify it.
