> Currently, in the case when we search for a bit set after a particular
> value, the bitmap has to be scanned from the beginning and
> rte_bitmap_scan() has to be called multiple times until we hit the value.
> 
> Add a new rte_bitmap_scan_from_offset() function to initialize scan
> state at the given offset and perform scan, this will allow getting
> the next set bit after certain offset within one scan call.
