[Qemu-stable] [PATCH for-2.0 35/47] dmg: use appropriate types when reading chunks

[Stefan Hajnoczi]

Use the right types instead of signed int:

  size_t new_size;

  This is a byte count for g_realloc() that is calculated from uint32_t
  and size_t values.

  uint32_t chunk_count;

  Use the same type as s->n_chunks, which is used together with
  chunk_count.

This patch is a cleanup and does not fix bugs.
