* Adding the missing roc:: namespace, effectively changing the value of RCCL_LIBRARY from rccl to roc::rccl.
The important difference is that rccl is treated as a symbolic "-lrccl" by linker (and fail the linking
due to a missing library search path), while roc::rccl is a target name, which can resolve into an absolute
library path.

* Adding a changelog entry
* minor updates to wording
* missing period

[ROCm/rccl commit: d5bea2cfaa]
This is a single commit of the source code changes required to
introduce support for multiple ranks per device.
A new interface (ncclCommRankInitMulti) has to be used to make use of
this new feature.
[ROCm/rccl commit: 0336ffdf70]
* Add another Rome model
* Add option to force enable intranet on single node
* Limit p2p channels to number of ranks
* Refine p2p channels handling
[ROCm/rccl commit: ef499c4810]
Improve allreduce performance when we have more than one network interface per
GPU and we need to use PXN to close rings.
Add support for PCI Gen5 on 5.4 kernels.
Fix crash when setting NCCL_SET_THREAD_NAME.
Fix random crash in init due to uninitialized struct.
Fix hang on cubemesh topologies.
Add P2P_DIRECT_DISABLE parameter to disable direct access to pointers within a
process.
[ROCm/rccl commit: 7aa1c46fd5]
Starting from rocm 5.2 there is a reorganization of the
include directories. This pr allows to compile
rccl on both the old and the new directory layout.
This solution is using find_package() for identifying correct
settings for rocm_smi starting from rocm-5.2, and the original (manual)
settings for all previous releases.
Tested with rocm-5.2, 5.1.1, 5.0.2, and 4.5.2.
[ROCm/rccl commit: 4c4a7cb696]
Tweak the signal handler and force non-release build
Increase ulimit locked memory value
Update the singal handler to use bfd symbol resolution.
Include configure logic to find bfd functions.
Add optionally c++ function name demangling
[ROCm/rccl commit: 2bf6d254b6]
* Fixing the broken library soft link
* Installing rccl.h wrapper to /opt/rocm-xxx/include path.
This missing wrapper was causing compilation errors with pytorch. Fixing it
[ROCm/rccl commit: b83efe9c5c]
Fix bug with CollNet
Fix bug with zero-bytes send/recv operations
Fix NCCL_PARAM implementation to avoid taking a lock on every call
Fix bug when setting NCCL_IB_QPS_PER_CONNECTION to more than one.
Improve error reporting for network errors.
[ROCm/rccl commit: 353e8ba446]
For easier interpretation of debug messages like "connection closed by
peer", "peer message truncated" and "peer collective mismatch"
