-- Addressed Kees's comments:

1. Non-atomic counters renamed to counter_simple32 and counter_simple64 to clearly indicate size.
2. Added warning for counter_simple* usage and it should be used only when there is no need for atomicity.
3. Renamed counter_atomic to counter_atomic32 to clearly indicate size.
4. Renamed counter_atomic_long to counter_atomic64 and it now uses atomic64_t ops and indicates size.
5. Test updated for the API renames.
6. Added helper functions for test results printing
7. Verified that the test module compiles in kunit env. and test module can be loaded to run the test.

Thanks for all of this!

8. Updated Documentation to reflect the intent to make the API restricted so it can never be used to guard object lifetimes and state management. I left _return ops for now, inc_return is necessary for now as per the discussion we had on this topic.

I still *really* do not want dec_return() to exist. That is asking for trouble. I'd prefer inc_return() not exist either, but I can live with it. ;)
