Marcin Smoczyński c74e7577c7 [EGD-3457] sys: improve workers destroying (#753) ...

Implement termination of worker threads. To achieve the goal so called
control queue has been introduced which is handled in Worker base class.
Once worker thread receives stop message it tries to kill itself. It is
possible to join a worker thread before deinit know thanks to a
semaphore given before thread termination.

Some improvements to the interface and implementation has been made
including state sanity checks. It is assumed that only service that owns
the worker is allowed to stop it, which allows not to consider code
reentrancy.

Worker destroying procedure has been updated in services that already
own workers.
