Merge remote-tracking branch 'mst/tags/for_anthony' into staging

acpi,pci,pc,virtio fixes and enhancements

This includes new unit-tests for acpi by Marcel,
hotplug for pci bridges by myself (piix only so far)
and cpu hotplug for q35.
And a bunch of fixes all over the place as usual.

I included the patch to fix memory alignment for q35
as well - even though it limits 32 bit guests to 3G (they
previously could address more memory with PAE).
To remove the limit, this will have to be fixed in seabios.

I also added self as virtio co-maintainer so I don't need
to troll the list for patches to review.
