### What problem does this PR solve? Issue Number: https://github.com/google/sanitizers/issues/189 Problem Summary: bthread需要额外适配ASan，不然会导致ASan误报。 ### What is changed and the side effects? Changed: 1. 在bthread创建、切换、销毁时，让ASan知道当前bthread的栈信息，主要用于维护[fake stack](https://github.com/google/sanitizers/wiki/AddressSanitizerUseAfterReturn)。 2. 主动对对象池中的内存进行下毒/消毒：get_object时消毒、return_object下毒，可以排查出对象被归还之后还继续被使用的问题。此外，ExecutionQueue的cancel功能在设计上允许TaskNode被归还到对象池后还能继续被使用，所以支持通过ObjectPoolWithASanPoison模板对象来禁用下毒/消毒功能。 3. 修复ASan发现的一些内存问题。 Side effects: - Performance effects(性能影响): - Breaking backward compatibility(向后兼容性): --- ### Check List: - Please make sure your changes are compilable(请确保你的更改可以通过编译). - When providing us with a new feature, it is best to add related tests(如果你向我们增加一个新的功能, 请添加相关测试). - Please follow [Contributor Covenant Code of Conduct](https://github.com/apache/brpc/blob/master/CODE_OF_CONDUCT.md).(请遵循贡献者准则). -- This is an automated message from the Apache Git Service.
