Merge remote-tracking branch 'remotes/kevin/tags/for-upstream' into staging

Block layer patches:

- Make truncate operations asynchronous (so that preallocation in
  blockdev-create doesn't block the main loop any more)
- usb-storage: Add rerror/werror properties
- nvme: Add num_queues property
- qemu-img convert: Copy offloading fixes (including data corruption fix)
- qcow2: Fix cluster leak on temporary write error
- Use byte-based functions instead of bdrv_co_readv/writev()
- Various small fixes and cleanups
