Usage: spiceusbredirection=NUMBER (default=0)

Enables spice usbredirection. Creates NUMBER usbredirection channels
for redirection of up to 4 usb devices from spice client to domU's qemu.
It requires an usb controller and if not defined will automatically adds
an usb2 controller.

Changes from v3:
- fixed condition that enable usbversion if it isn't defined in presence
  of usbredirection enabled

Changes from v2:
- updated for usbversion patch v7
- now usbredirection cannot be used with usb and usbdevice parameters
- if usbversion is undefined it will creates an usb2 controller

Changes from v1:
- Now can be setted the number of redirection channels.
- Various code improvements.

It looks correct from the QEMU arguments POV

It looks like this patch depends on the usb2/3 patch you have posted 
separately.  Having to keep track of which patch depends on what -- 
particularly if they have different versions, as we have here -- makes 
it much more difficult for maintainers to figure out what's going on; 
that tends to make it so that you keep getting put in the "deal with it 
later" bucket.

If you put related changes in a patch series, it will be easier to keep 
track of.  (See http://wiki.xenproject.org/wiki/Submitting_Xen_Patches 
for a description of how to do this with git send-email .)
