* most usages are drop-in replacements
* occasionally the other convenience functions can be used
* verify call-paths from core code to identify usages
* ensure reseeding for all tests involving some kind of randomness...
__Note__: some tests were not yet converted,
since their usage of randomness is actually not thread-safe.
This problem existed previously, since also `rand()` is not thread safe,
albeit in most cases it is possible to ignore this problem, as
''garbled internal state'' is also somehow „random“
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.
...which showed up under high system load.
The initialisation of the member variables for the check sum
could be delayed while the corresponding thread was already running
the (trivial) implementation turned out to be correct as written,
but it was (again) damn challenging to get the mulithreaded chaotic
test fixture and especially the lambda captures to work correct.
...while tests in the library subdirectory are linked only against
liblumierasupport, which does not provide the multithreading support
In this special case here the actual facility to be tested does not rely
on thread support, only on locking. But the stress test obviously needs
to create several threads. Simple workaround is to move the test into
a test collection linked against all of the application core...
