BufferProvider: looking for ways to disentangle the implementation (see #1410)

Browse source 
The outward interface has stood the test of time quite well.
But the back-side towards the implementation is a tangled mess,
presumably due to being developed from prototyping code: the
actual implementation is completely overgrown by diagnostics
and test instrumentation, since running in unit test setup
was the only actual usage of this code ever since.

My first attempt with decomposing into a decorator-chain failed.
Thus the new line of attack is to introduce two implementation
pillars right from top-level
- `BufferStage` : the state and metadata handling
- `BufferStore` : the storage backend
These are defined as nested interfaces, and the further refactoring
starts with subclassing everything, nested as it is.

also die Basis-Impl des BufferProviders mu&#223; ohnehin eine Konfigurations-M&#246;glichkeit bekommen, insofern nicht mehr der Konstruktor selber die Implementierungs-Komponenten erzeugen darf. Deshalb k&#246;nnte man die gesamte bisherige Struktur erhalten, und h&#228;tte dann erst mal aufgedoppelte Vererbungs-Ketten, die dann in einem zweiten Schritt aufzur&#228;umen w&#228;ren.

Per Dekret wird festgestellt: alles was bisher in Subklassen passiert ist, war letztlich Implementierung der Speicherverwaltung. Also wird es ohne R&#252;cksicht auf Verluste in die Implementierungsklasse des BufferStore gedr&#252;ckt. Daraufhin brechen praktisch alle Verwendungen und m&#252;ssen schrittweise repariert werden. Am Ende befindet sich der ganze M&#252;ll im HeapMemProvider. Und so wollte ich es ja &#8212; um dann das Tracking gar nicht mehr verstehen zu m&#252;ssen, sondern direkt sauber neu zu implementieren.

...da sind wir wieder bei dem Thema mit einer kompletten Trennung von Interface und Implementierung: eine solche Trennung w&#252;rde mich zwingen, alle Methoden entweder virtuell zu machen, oder komplett aufzudoppeln.
