Changed stream wait timeout counter to be 16-bit, so that very long timeout periods can be set for correct communications with badly designed hosts or devices which greatly exceed the USB specification limits. 

Mass Storage Host demo now uses a USB_STREAM_TIMEOUT_MS of two seconds to maintain compatibility with poorly designed devices.
