Hi,
This series is mostly code rearrangement (cleanups) to be
able to split the hardware code from the block driver code,
to be able to use multiple queues on the same hardware, or
multiple block drivers on the same hardware.
Missing review: 1, 2, 5, 6, 8, 12.
Since v1:
- rebased
- use SCALE_MS definition
- added Stefan's R-b
- addressed Stefan's review comments
- use union { NvmeIdCtrl / NvmeIdNs }
- move irq_notifier to NVMeQueuePair
- removed patches depending on "a tracable hardware stateo
object instead of BDRVNVMeState".
Please review,
Phil.

[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
