Perform exact matching when the prefix "=" is specified in the NCCL_IB_HCA variable to exclude HCAs mlx5_X[0-9]+ when mlx5_X is specified.

* Refactor primitive test to support multiple GPUs in rings
* Make GPUs sync before transfer optional
* Use same ring format as RCCL
* Extend to 8 GPUs and report errors if there is no P2P access
* Control GPUs sync before ops from command line with "-s" option
* Change buffer size through command line option "-n"
Rename iterations command line option to "-i"

Current SHM object name would only use pidHash and ranks as
identification, which would collide each other when program runs with
multiple communicators. Here we added commId info into pidHash, it makes
'pidHash'es of different communicators keeping in same process will be
distincted with each other.

Makes a change to allow the user to select between the static CUDA
runtime library (default) and the dynamic CUDA runtime library. Does
this by allowing `CUDARTLIB` to be overridden.

The shared memory filename was only based on the destination. While
this was OK for rings since only one rank would send data to a given
rank, it would crash with trees because they communicate in both
directions.
