Do we really want to make this change? It makes maintenance harder to
reason about. I'd lean instead towards adding a single internal header,
where we #define VIR_ALLOC_N, so that existing code can continue to use
the nicer interface (where it's harder to typo the sizeof(*var)*len).
Furthermore, VIR_ALLOC_N has bounds checking (it ensures OOM failure if
sizeof()*len would overflow) that you are losing in your rewrite.
