5fba42c21b qemu: Probe for a few params supported by migrate-set-parameters
These parameters were originally set via dedicated commands which are
now deprecated. We want to use migrate-set-parameters instead if
possible.

9ce32b0935 qemu: Introduce fw_cfg capability
This capability tracks whether QEMU supports -fw_cfg command line
option, more specifically whether it allows specifying filename.

There are some releases of QEMU which support -fw_cfg but not
filename. If this is ever a problem we can refine the capability
later on.

3b7ca6d419 qemu: capabilities: Introduce QEMU_CAPS_VIRTIO_BLK_SCSI_DEFAULT_DISABLED
Historically the 'scsi' passthrough feature of virtio-blk-pci
was enabled by default. Libvirt was disabling it due to security
implications outlined in libvirt commit v0.9.9-4-g177db08775 if it was
not explicitly requested. In qemu commit v2.4.0-1566-ged65fd1a27 the
default value was changed to disabled in preparation for virtio-1.
Starting from QEMU-5.0 the 'scsi' property was also deprecated. There
replacement for the functionality is to use 'virtio-scsi' for the
purpose. This isn't a direct replacement though.

Add capability named QEMU_CAPS_VIRTIO_BLK_SCSI_DEFAULT_DISABLED which
allows us to stop formatting the 'scsi=' property if it's disabled by
default and not requested so that we don't use deprecated features.

blockdev support has been introduced.
