Add network communication through another GPU connected with NVLink (PXN). Add aggregation of messages coming from different local GPUs through PXN and going to the same destination. Add new v5 plugin API with grouped receives and tags. Add compat for v4 plugins. Add naming of NCCL threads to help debugging. Fix NVLink detection and avoid data corruption when some NVLinks are down. Add support for Relaxed Ordering for IB. Add profiling and timing infrastructure.
