Add 'group' properties to 'vfio-pci' device. This allows
to add vfio-pci device using precreated vfio container and group, e.g.
-object vfio-container,id=ct,fd=5 \
-object vfio-group,id=grp,fd=6,container=ct \
-device vfio-pci,host=05:00.0,group=grp

Add avocado test for vfio subsystem. The test uses pci-tesdev as a source
PCI device for vfio. So the test supposed to be launched inside QEMU
guest launched with '-device pci-testdev' devices.
The test creates VFIO container&group, launches QEMU and passes
container/group/device to it.

These patches add possibility to pass VFIO device to QEMU using file
descriptors of VFIO container/group, instead of creating those by QEMU.
This allows to take away permissions to open /dev/vfio/* from QEMU and
delegate that to managment layer like libvirt.
The VFIO API doen't allow to pass just

Add vfio-container type and allow user to create vfio-container
object via '-object' command line argument or 'object-add' qmp command.
Add 'fd' parameter to this type to allow user provide file descriptor of
a vfio-container.
E.g.
-object vfio-container,id=ct,fd=5

Add vfio-group type and allow user to create such object via
'-object' command line argument or 'object-add' qmp command.
Parameters are:
- @fd - file descriptor
- @container - id of vfio-container object which will be used for
this VFIO group
- @groupid - number representing IOMMU group

When tmpfs is NULL, a build warning is seen with GCC 9.3.0.
It's strange that GCC 11.2.0 on Ubuntu 22.04 does not catch this,
neither did the QEMU CI.
