capable of creating hugetable-backed memfd. However, it may fail
at runtime depending on requested "hugetlbsize".

Previous commits removed all capabilities from per-device property
probing for:

  pci-assign
  kvm-pci-assign
  usb-host
  scsi-generic

Remove them from the virQEMUCapsDeviceProps list and get rid of the
redundant device-list-properties QMP calls.

Note that 'pci-assign' was already useless, because the QMP version
of the device is called 'kvm-pci-assign', see libvirt commit 72574808
from 2012.

The field was added in qemu v0.13.0-rc0-731-g1ca4d09ae0 so all supported
qemu versions now use it.

There's a LOT of test fallout as we did not use capabilities close
enough to upstream for many of our tests.

Several tests had a 'bootindex' variant. Since they'd become redundant
they are also removed here.

Since QEMU 2.10, it's possible to use a new type of display -
egl-headless which uses drm nodes to provide OpenGL support. This patch
adds a capability for that. However, since QEMU doesn't provide a QMP
command to probe it, we have to base the capability on specific QEMU
version.

The capability also represents that 'blockdev-add' is functional. It's
necessary to detect it via presence of 'blockdev-del' since blockdev-add
did not have the unsupported 'x-blockdev-add' version previously and
thus would be marked as present even if we could not use it.

Commit 766d5c1b deprecated the capability, because we were assuming
