Lock-free GamepadSeqLock (try 2)
The change
- provides an improved lock-free SeqLock implementation which eliminates any potential blocking of readers.
- provides a higher-level and simpler API as was suggested by Darin.
- ThreadSanitizer report suppressions are replaced with correct synchronization.
- eliminates nasty kMaximumContentionCount and associated histogram.
