Recent versions of qemu added the -netdev vhost-vdpa device. This
capability allows libvirt to know whether this is supported.

adb9f7123a qemu: capabilities: Add QEMU_CAPS_BLOCK_EXPORT_ADD
The 'block-export-add' QMP command is a replacement for 'nbd-server-add'
and will allow greater flexibility. Add a capability so that we can
switch to it.

b647654cbb qemu: Track default-ram-id machine attribute
The machine structure has another (optional) attribute:
default-ram-id, which specifies the alias of the default RAM
object. While the alias is private, it can never change in order
to not break migration. QEMU uses the alias when allocating
regular, not NUMA memory. In order to switch to new command line
and maintain migration, save this ID.

66c5674e79 qemu_capabilities: Add QEMU_CAPS_USB_HOST_HOSTDEVICE
This capability tracks whether "usb-host" device has "hostdevice"
attribute. This attribute allows us to specify full path to the
USB device ("/dev/bus/usb/$bus/$dev") but more importantly, since
QEMU uses qemu_open() for this attribute it allows us to pass
pre-opened FD and have QEMU not bother with opening the file at
all.

The attribute was added in v5.1.0-rc0~71^2~1 QEMU commit.

86628e0cff qemucapabilitiesdata: Add test data for x86_64 for the qemu-5.2 dev cycle
The machine types for this cycle were already added and qemu also added
a property for the machine type object called "default-ram-id".

Also "block-bitmap-mapping" is supported as a migration parameter.
