[PATCH v2 00/11] virtio-sound migration part 1

[Volker Rümelin]

Here is the first part of my virtio-sound patches. Most of them are a
preparation to make migration work. Patch 10/11 enables migration.

The second part isn't finished yet and will have to do with virtio-sound
jack and channel maps configuration and migration.

Patch 01/11 "hw/audio/virtio-sound: return correct command response
size", patch 02/11 "hw/audio/virtio-sound: fix segmentation fault in
tx/rx xfer handler" and patch 05/11 "hw/audio/virtio-sound: free all
stream buffers on reset" are candidates for stable-8.2. Patch 05/11
either needs patches 03/11 and 04/11 or has to be rewritten for stable-8.2.

v2:
The patches were reordered to facilitate the backport of 3 patches to
QEMU stable-8.2.

Patch 02/11 "fix segmentation fault in tx/rx xfer handler" has been
completely rewritten.

Patch 04/11 "hw/audio/virtio-sound: allocate an array of streams" has
been renamed. The subject and the commit message describe the patch better.

Patch 05/11 "hw/audio/virtio-sound: free all stream buffers on reset" is
an additional patch.

Patch 07/11 "hw/audio/virtio-sound: add stream state variable" resets
the state variable on reset. Once a stream has been opened, it will only
be closed after a reset or when QEMU shuts down.

Patch 10/11 "add missing vmstate fields" resets the inuse variables on
reset.
