<disk> devices lack the model= attribute which is used by
most other device types. bus= mostly acts as one, but it
serves other purposes too like determing what target=
prefix to use, and for matching against controller type=
values.

Extending bus= to handle additional virtio transitional
devices will complicate apps lives, and it isn't a clean
mapping anyways. So let's bite the bullet and add a new
<disk model=X/> attribute, and wire up common handling
for virtio and virtio-{non-}transitional

The QEMU command line arguments are very long and currently all written
on a single line to /var/log/libvirt/qemu/$GUEST.log. This introduces
logic to add line breaks after every env variable and "-" optional
argument, and every positional argument. This will create a clearer log
file, which will in turn present better in bug reports when people cut +
paste from the log into a bug comment.

An example log file entry now looks like this:

If virSecretGetSecretString is using by secretLookupByUUID,
then it's possible the found sec->usageType doesn't match the
desired @secretUsageType. If this occurs for the encrypted
volume creation processing and a subsequent pool refresh is
executed, then the secret used to create the volume will not
be found by the storageBackendLoadDefaultSecrets which expects
to find secrets by VIR_SECRET_USAGE_TYPE_VOLUME.

along with an error indicating the incorrect matched types.

The QEMU validation code for graphics has been in place for a while, but
because it is only executed from virDomainDeviceInfoIterateInternal, it
was never run, since the iterator expects the device to have boot info
which graphics don't have. The unfortunate side effect of this whole mess
was that a few capabilities were missing from the test suite (as commit
d8266ebe demonstrated with graphics-spice-invalid-egl-headless test),
which in turn meant that a few graphics tests which expected a failure
happily accepted any failure the test runtime returned which made them
succeed. The impact of this was that we then allowed to start a domain
with multiple OpenGL-enabled graphics devices.

This patch enables iteration over graphics devices. Unsurprisingly,
a few tests started to fail as a result, so fix those too.

It's fairly easy to forget to add a capability to the list of

unfortunate results. Therefore, introduce negative versions of
DO_TEST_CAPS_LATEST macros, so that real QEMU caps can be used with
tests that expect a failure too.

Up until now, we formatted 'rendernode=' onto QEMU cmdline only if the
user specified it in the XML, otherwise we let QEMU do it for us. This
causes permission issues because by default the /dev/dri/renderDX
permissions are as follows:

crw-rw----. 1 root video

There's literally no reason why it shouldn't be libvirt picking the DRM
render node instead of QEMU, that way (and because we're using
namespaces by default), we can safely relabel the device within the
namespace.
