int gnet_stats_finish_copy (struct gnet_dump * d);
Corrects the length of the top level TLV to include all TLVs added by gnet_stats_copy_XXX calls. Adds the backward compatibility TLVs if gnet_stats_start_copy_compat was used and releases the statistics lock.
Returns 0 on success or -1 with the statistic lock released if the room in the socket buffer was not sufficient.
