usb: use iovecs in USBPacket
Zap data pointer from USBPacket, add a QEMUIOVector instead. Add a bunch of helper functions to manage USBPacket data. Switch over users to the new interface. Note that USBPacket->len was used for two purposes: First to pass in the buffer size and second to return the number of transfered bytes or the status code on async transfers. There is a new result variable for the latter. A new status code was added to catch uninitialized result. Nobody creates iovecs with more than one element (yet). Some users are (temporarely) limited to iovecs with a single element to keep the patch size as small as possible. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
