While qemu supports the 'transaction' command since v1.1.0
(52e7c241ac766406f05fa) and the 'blockdev-snapshot-sync' command since
v0.14.0-rc0 we need to keep the capability bits present since some qemu
downstreams (RHEL/CentOS 7 for example) chose to cripple qemu by
arbitrarily compiling out some stuff which was already present at that
time.
To simplify the crazy code just require both commands to be present at
the beginning of an external snapshot so that we can remove the case when
'transaction' would not be supported.
This also allows to drop any logic connected to the
VIR_DOMAIN_SNAPSHOT_CREATE_ATOMIC flag since snapshots are atomic with
the 'transaction' command.

virCopyLastError is intended to be used after last error is set.
However due to virLastErrorObject failures (very unlikely though
as thread local error is allocated on first use) we can have zero
fields in a copy as a result. In particular code field can be set
to VIR_ERR_OK.
In some places (qemu monitor, qemu agent and qemu migaration code
for example) we use copy result as a flag and this leads to bugs.
Let's set OOM-like error in copy in case of virLastErrorObject failures.

Historically, we've always enabled an emulated video device every time we
see that graphics should be supported with a guest. With the appearance
of mediated devices which can support QEMU's vfio-display capability,
users might want to use such a device as the only video device.
Therefore introduce a new, effectively a 'disable', type for video
device.

Since QEMU 2.12, QEMU understands a new vfio-pci device option 'display'
which can be used to turn on display capabilities on vgpu-enabled
mediated devices, IOW emulated GPU devices like QXL will no longer be
needed with vgpu-enable mdevs.
QEMU defaults to 'auto' for the 'display' attribute, which is not
foolproof, so we need to play it safe here and default to display='off'
if this attribute wasn't provided in the XML explicitly.

QEMU 2.12 introduced a new type of display for mediated devices using
vfio-pci backend which allows a mediated device to be used as a VGA
compatible device as an alternative to an emulated video device. QEMU
exposes this feature via a vfio device property 'display' with supported
values 'on/off/auto' (libvirt will default to 'off').
This patch adds the necessary bits to domain config handling in order to
expose this feature. Since there's no convenient way for libvirt to come
up with usable defaults for the display setting, simply because libvirt
is not able to figure out which of the display implementations - dma-buf
which requires OpenGL support vs vfio regions which doesn't need OpenGL
(works with OpenGL enabled too) - the underlying mdev uses.

Since 2.10 QEMU supports a new display type egl-headless which uses the
drm nodes for OpenGL rendering copying back the rendered bits back to
QEMU into a dma-buf which can be accessed by standard "display" apps
like VNC or SPICE. Although this display type can be used on its own,
for any practical use case it makes sense to pair it with either VNC or
SPICE display. The clear benefit of this display is that VNC gains
OpenGL support, which it natively doesn't have, and SPICE gains remote
OpenGL support (native OpenGL support only works locally through a UNIX
socket, i.e. listen type=socket/none).
