Compatibility with NVSHMEM

NVSHMEM follows semantic versioning for its releases and packages per commit i.e MAJOR.MINOR.PATCH.TWEAK.

Each component of the version is monotonically increasing number. So, if the author makes non-source change e.g. test, perftest, etc, it would require updating TWEAK component of the version.
If the author makes a change to the source file, but not the ABI or API, it is PATCH change by 1 and TWEAK resets.
If the author makes a change to the API/ABI definition in a backward compat way, it is MINOR change by 1 and TWEAK/PATCH reset to 0.
If the author makes a change to the ABI/API definition in the non-backward compat way, it is MAJOR change by 1 and TWEAK/PATCH/MINOR resets to 0.
