A couple of improvements to tracing that have come out of helping
people with migration problems:
  * vmstate_n_elems trace the count/name - for when you have problems
    getting array counts right
  * vmstate_subsection_load_bad - add the idstr, for when you receive a
    subsection you weren't expecting.

This changes qcow2 to implement the byte-based .bdrv_co_pwritev
interface rather than the sector-based old one.

As preallocation uses the same allocation function as normal writes, and
the interface of that function needs to be changed, it is converted in
the same patch.

This patch follows guidelines of all other tracepoints in qcow2, like ones
