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
capabilities for a negative test case which might yield (for us) very
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.

The networkxml2firewalltest sets virCommand to dry run mode but doesn't
provide a callback to fill in stdout/stderr. As a result when the
firewall code queries rules it gets a NULL output and so never triggers
the callback to process output.

This trivial change just returns an empty string for the command output
in order to ensure the callback gets triggered. It has no effect right
now, but in future patches this will trigger greater test coverage.

Depending on whether QEMU actually supports the option, we can put the

Unlike with SPICE and SDL which use the <gl> subelement to enable OpenGL
acceleration, specifying egl-headless graphics in the XML has
essentially the same meaning, thus in case of egl-headless we don't have
a need for the 'enable' element attribute and we'll only be interested
in the 'rendernode' one further down the road.

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.

Add a new memoryBacking source type "memfd", supported by QEMU (when
the capability is available).

A memfd is a specialized anonymous memory kind. As such, an anonymous
source type could be automatically using a memfd. However, there are
some complications when migrating from different memory backends in
qemu (mainly due to the internal object naming at this point, but
there could be more). For now, it is simpler and safer to simply
introduce a new source type "memfd". Eventually, the "anonymous" type
could learn to use memfd transparently in a separate change.

The main benefits are that it doesn't need to create filesystem files,
and it also enforces sealing, providing a bit more safety.
