Since 133fb140 moved the validation of a video device into a separate

been the same for both the primary device and the secondary devices.
Let's merge these and thus handle all the devices within the existing
'for' loop.

QEMU uses a shorthand '-sdl' which maps to '-display sdl'. However, if
there are any options to be passed to SDL, the full command version must
be used. Everything seemingly worked for us until commit 5038b300
introduced OpenGL support for SDL and added ',gl=on/off' option which as
mentioned above could have never worked with the shorthand version of
the command. Indeed starting a domain with an SDL display and OpenGL
enabled, QEMU produces a rather cryptic error:

-sdl: Could not open 'gl=on': No such file or directory

This patch provides fixes to both the SDL cmdline generation and the
test suite.

When support was adding for passing a pre-opened listener socket to UNIX

chardevs too with predictable amounts of fail resulting. This affects
libvirt when using QEMU >= 2.12

passing when operating in server mode.

QEMU chardevs have a bug which makes the vhostuser backend complain
about lack of support for FD passing when validating the chardev.
While this is ultimately QEMU's responsibility to fix, libvirt needs to
avoid tickling the bug.

Simply disabling chardev FD passing just for vhostuser's chardev is
the most prudent approach, avoiding need for a QEMU version number
check.

When creating a snapshot with --quiesce an async job is grabbed
and just before executing guest fs-freeze command an agent job is
grabbed. This is achieved by calling

  qemuDomainObjBeginJobInternal(job = QEMU_JOB_NONE,
                                agentJob = QEMU_AGENT_JOB_MODIFY);

Since there already is an async job set on the domain (by the
same thread) qemuDomainNestedJobAllowed(priv, job) is consulted
if @job is allowed by job mask. But this function returns false
(meaning sync @job is not allowed) which leads to a deadlock.
