This checker finds STL thread primitives misuse.

- std::mutex::unlock without std::mutex::lock
- std::mutex::lock twice

In future:

- std::mutex::lock without std::mutex::unlock (discuss)
- std::recursive_mutex support

P.S. This is an alpha version of my first checker. Do not hesitate to express your complaints!
