### What problem does this PR solve? Issue Number: resolve Problem Summary: - bthread_id accesses butex state words as plain uint32_t values even though butex manages them as atomic state. Concurrent bthread_id_join() and bthread_id_unlock_and_destroy() can therefore form a C++ data race. What is changed and the side effects? Changed: - Store ID butex state as butil::atomic<int>. - Centralize atomic version-word access helpers. - Add a concurrent join/destroy regression test. Side effects: - Performance effects: - Breaking backward compatibility: --- ### Check List: - Please make sure your changes are compilable. - When providing us with a new feature, it is best to add related tests. - Please follow [Contributor Covenant Code of Conduct](https://github.com/apache/brpc/blob/master/CODE_OF_CONDUCT.md). -- This is an automated message from the Apache Git Service.
