block: Change bdrv_commit to handle multiple sectors at once bdrv_commit copies the image to its backing file sector by sector, which is (surprise!) relatively slow. Let's take a larger buffer and handle more sectors at once if possible. With a 1G qcow2 file, this brought the time bdrv_commit takes down from 5:06 min to 1:14 min for me.
