stream: pass new base image format to bdrv_change_backing_file

When an image is modified to point to the new backing file, the backing
file format is set to NULL, which means auto-probe. This is wrong, in

stream: fix ratelimiting corner case

This fixes inability to make progress in streaming if the quota is set
to less than the amount of data that an I/O operation has to write.

In this case, limit->dispatched + n will always be above the quota and,

block: wait for job callback in block_job_cancel_sync

The limitation on not having I/O after cancellation cannot really be
kept. Even streaming has a very small race window where you could
cancel a job and have it report completion. If this window is hit,...
