[Qemu-block] [PATCH v2 0/6] Acquire the AioContext during _realize() |

This series acquires the AioContext in the _realize() functions of
several devices before making use of their block backends. This fixes
at least a couple of crashes (in virtio-blk and scsi). The other
devices don't currently support iothreads so there's no crashes.

v2:
- Patch 1: include a test case [Kevin]
- Patch 2: include a test case and extend the locking to protect more
function calls [Kevin]
v1: https://lists.gnu.org/archive/html/qemu-block/2019-01/msg00259.html
- Initial version
Output of backport-diff against v1:
Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
