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

Block layer patches and object-add QAPIfication

- QAPIfy object-add and --object
- stream: Fail gracefully if permission is denied
- storage-daemon: Fix crash on quit when job is still running
- curl: Fix use after free
- char: Deprecate backend aliases, fix QMP query-chardev-backends
- Fix image creation option defaults that exist in both the format and
  the protocol layer (e.g. 'cluster_size' in qcow2 and rbd; the qcow2
  default was incorrectly applied to the rbd layer)
