* Batch P2P operations (2 per CU/channel) and update channel-part mapping
- Revert bitreversal and fix channel mapping to be compatible with P2P batching and avoid hangs
- P2P batching is only used for more than 2 nodes to avoid aggregating intra-node traffic when it is dominant for less than 2 nodes
* Address single node regression and channel per net peer
* Add batching threshold
* Add enable switch for batching
* Update CHANGELOG.md
* Add minor comment change
* Update CHANGELOG.md

- Introduced double-buffering to reduce copy overhead and overlap BF16 arithmetic with data prefetching.
- Aimed to improve performance of reduction-based collectives by up to 10%.
- Implemented based on recommendations from Guennadi Riguer (AMD)
- Added --force-reduce-pipeline option to install.sh to activate this optimization for BF16 reductions.
- Feature is disabled by default to prevent regressions with large messages until auto-tuning logic is upstreamed.

* Added RCCL env params to control setting the SO_REUSEADDR and SO_LINGER socket options. This can allow control over the number of file descriptors created during bootstrapping.
* Casted the linger value to `int` sooner to avoid a scope of unknown typed-ness.
* Added CHANGELOG entry for this feature.
* Update rccl changelog for 6.3.1
* Fix version number
* Correct RCCL release version
* Added details to 6.3.0 changelog

* Reduce AlltoAll port usage when connecting proxy
Reuse socket ports when connecting proxies in AlltoAll.
Existing port usage in AlltoAll is O(n) for recv and O(n) for send,
reusing socket ports in server or client side will make one of them
O(1), reusing both will reduce the total port usage to O(1) and enables
AlltoAll in >64 MI200 nodes.
* Update changelog accordingly
Update changelog accordingly.
