[PATCH v4 03/16] win-usb-dev: Track device redirection operations in progress

[Dmitry Fleytman <dmitry@xxxxxxxxxx>]

From: Kirill Moizik <kmoizik@xxxxxxxxxx>

This commit introduces redirecting property of GUdevClient

This property indicates when a redirection operation
is in progress on a device. It's set back to FALSE
once the device is fully redirected to the guest.
