[libvirt] [PATCH v3 0/4]use newer video device by -device in qemu commandline



v2: Check qemu version, it has to be qemu >= 1.2 for using
    new video device with -device qemu option
v3: Add a new caps bit QEMU_CAPS_1DOT20_PLUS to mark qemu >= 1.2
    Add a new testcase for improved qemu commandline
    Fixed all placed pointed out in v2

This patch set aims to use qemu VGA device with -device option to replace
-vga option. The mapping is as follows.

'-device VGA' maps to '-vga std'
'-device cirrus-vga' maps to '-vga cirrus'
'-device qxl-vga' maps to '-vga qxl'
    (there is also '-device qxl' for secondary devices)
'-device vmware-svga' maps to '-vga vmware'

Through this change, guests will be able to use any available PCI slot
number rather than fixed 0x2 slot for primary video device.
