I hereby agree to the terms of the CLA available at: https://databend.rs/dev/policies/cla/

Summary

After this PR:

  • remove useless code in common_base::infallible, they are just some wrappers, we can use parking_lot or std::sync

    • the Mutex in std is likely to perform better and we can use it.

  • for ReentrantMutex & ReentrantMutexGuard in parking_lot

    • ReentrantMutexGuard does not give mutable references to the locked data. Use a RefCell if you need this.
    • but RefCell is !Sync, perhaps we could use threadsafe AtomicRefCell
