This function was introduced in commit 41f5c2ca2776 as a way
to probe the same property for multiple devices at once.
Although the resulting representation is very compact, it
doesn't provide any extra features compared to the existing
virQEMUCapsProcessStringFlags() mechanism, which is already
used for pretty much all device properties.
Drop the custom function and datatypes and start using the
standard ones instead.
Note that, in theory, the end result is not identical
because we're no longer probing properties for
virtio-serial-pci
virtio-9p-pci
virtio-rng-pci
virtio-input-host-pci
virtio-keyboard-pci
virtio-mouse-pci
virtio-tablet-pci
However, chances of any of those devices being compiled
into a QEMU binary where
virtio-balloon-pci
virtio-blk-pci
virtio-scsi-pci
virtio-net-pci
virtio-gpu-pci
are compiled out are slim enough that it doesn't make any
difference in practice, as the lack of test suite churn
shows.
