add qxl2 (2monitors),qxl3 (3monitors),qxl4 (4monitors) vga type.
For linux, we only need 1 qxl card with more memory
For windows, we need 1 qxl card by monitor
Original Information from spice-mailing

You need to specify multiple devices for Windows VMs. This is what
libvirt gives me (via 'virsh domxml-to-native qemu argv DOMAIN_XML'):
<...> -vga qxl -global qxl-vga.ram_size=67108864 -global qxl-vga.vram_size=33554432 -device qxl,id=video1,ram_size=67108864,vram_size=33554432 -device qxl,id=video2,ram_size=67108864,vram_size=33554432 -device qxl,id=video3,ram_size=67108864,vram_size=33554432
For Linux VM, just one qxl device is OK but then it's advisable to
increase the available RAM:
<...> -vga qxl -global qxl-vga.ram_size=134217728 -global qxl-vga.vram_size=33554432
If you don't turn off surfaces, then you should increase vram size to
say 64 MB from current default of 32 MB.

Currently offline migration fail ,because we are trying to check with qmp the spiceserver status.
This should be done online only.
I also add eval, to avoid migration lock if qmp query fail.

This patch adds support for unsecure migration using a direct tcp connection
KVM <=> KVM instead of an extra SSH tunnel. Without ssh the limit is just the
bandwith and no longer the CPU / one single core.
You can enable this by adding:
migration_unsecure: 1
to datacenter.cfg
Examples using qemu 1.4 as migration with qemu 1.3 still does not work for me:
current default with SSH Tunnel VM uses 2GB mem:

That way we do not need to run qmp command to get the port.
Set spice ticket expire time to 30 (5 seconds seems a bit too short).
Coding style cleanups.
