usb: add support for microsoft os descriptors
This patch adds support for special usb descriptors used by microsoft windows. They allow more fine-grained control over driver binding and adding entries to the registry for configuration. As this is a guest-visible change the "msos-desc" compat property has been added to turn this off for 1.7 + older Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
