Bump major driver version number from 3 to 4. The main new feature is the removal of the fixed 16 element array of requests per file descriptor. It is replaced by a xarray (eXtensible array) in their parent which is a sg_fd object (i.e. a file descriptor). The sg_request objects are not freed until the owning file descriptor is closed; instead these objects are re-used when multiple commands are sent to the same file descriptor.
