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

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. For backwards compatibility, if a certain qemu version does not support one of the above video device arguments to -device or even -device itself, the -vga will still be used.
