chg: dev: Move the library initialization and shutdown to executables

Instead of relying on unreliable order of execution of the library
constructors and destructors, move them to individual binaries.  The
advantage is that the execution time and order will remain constant and
will not depend on the dynamic load dependency solver.

Merge branch 'ondrej/move-the-constructors-destructors-to-binaries' into 'main'
