* 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.
* ext-src: add MSCCLPP memory registration APIs
* update mem-reg patch with mscclpp helper routine to check if buffer is registered
* RCCL integration of MSCCL++ user-buffer registration APIs
* only include mscclpp_nccl header if ENABLE_MSCCLPP is defined
* ext-src: update mscclpp mem-reg patch
* add helper routine to patch
* check handle before MSCCL++ deregister
* fix typo to replace send buff with recv buff
* in case of no mscclpp registration, dduring deRegister call, ont fall back to rccl deRegister which will return an error
* Apply suggestions from code review
Whitespace suggestions and reducing diffs to avoid future merge conflicts

* rename helper functions and change their return type
* set RCCL user-buffer registration to occur if attempting MSCCL++ registration with a buffer in managed memory

It seems like here wants to check xgmi_node instead. If checks node for "nvlink", it will verify the link_info everytime.
If checks node for "xgmi", when get yes answer, it won't need check vsmi topo interface.
* Switched calls to `cudaMemcpyAsync` to be `cudaMemcpy` in `ncclTransportP2pSetup` to avoid race condition with `cudaIpcOpenMemHandle` inside p2p `connect`. See `ncclP2pImportShareableBuffer`.
* Moved synchronize outside of the loop, as it isn't necessary to sync between every iteration of the loop.
Certain CMake functions deduplicates arguments by default. For example, if we
have two `target_link_options` with both `-Xoffload-linker -opt-A` and then
`-Xoffload-linker -opt-B`, the final link command would be `-Xoffload-linker
-opt-A -opt-B`, which is not what we want.
