Subject: [PATCH] Support <video> element for QEMU guests

	* src/qemu_conf.c, src/qemu_conf.h: Use -vga or -std-vga
	when starting guests if video card is present
	* tests/qemuhelptest.c: Change to use constants instead
	of hardcoded hex numbers, and add VGA support
	* tests/qemuxml2argvdata/qemuxml2argv-graphics-sdl-fullscreen.xml,
	tests/qemuxml2argvdata/qemuxml2argv-graphics-sdl.args,
	tests/qemuxml2argvdata/qemuxml2argv-graphics-sdl.xml,
	tests/qemuxml2argvdata/qemuxml2argv-graphics-vnc-sasl.args,
	tests/qemuxml2argvdata/qemuxml2argv-graphics-vnc-sasl.xml,
	tests/qemuxml2argvdata/qemuxml2argv-graphics-vnc-tls.xml,
	tests/qemuxml2argvdata/qemuxml2argv-graphics-vnc.xml,
	tests/qemuxml2argvdata/qemuxml2argv-input-xen.xml: Add <video>
	element for testing graphics adapter
	* tests/qemuxml2argvtest.c: Add QEMUD_CMD_FLAG_VGA flag
	* tests/qemuxml2xmltest.c: Add missing graphics-vnc-sasl/tls tests
