This is Step-2 : change the API towards application Notably all invocation variants to support member functions or a reference to bool flags are retracted, since today a λ-binding directly at usage site tends to be more readable. The function names are harmonised with the C++ standard and emergency shutdown in the Subsystem-Runner is rationalised. The old thread-wrapper test is repurposed to demonstrate the effectiveness of monitor based locking.
