FS#10239 - USB storage write caching

WARNING : this patch works for me, but it doesn’t have any error checking and is therefore likely to eat data every now and then

This patch adds a write queue to improve write speeds by allowing fully overlapping usb and disk operations. This significantly improves write speed. In some cases it gets better than the OF.

Work needed before this is in any way ready to commit includes extending the SCSI handling to tell the host that we do write caching.
