BufferProvider: complete the clean-up effort

Browse source 
Looking through all my work notes, it seems that all the
problematic aspects are now solved in a satisfactory way.
 * it is clear how to dependency-inject a `BufferProvider`
 * the internals of the `BufferProvider` front-End have been restructured
 * there are now two ''pillars'' of the implementation: `BufferStage` and `BufferStore`
 * both can be subclassed independently
 * `BufferProviderSetup` exposes a proxying-mechanism (used for `DiagnosticBufferProvider`)
 * the `BufferMetadata` have been reviewed and some minor details were rectified
 * after a re-Design of `OutputSlot`, `BuffHandle` can now be used as unified front-End
 * both `DiagnosticBufferProvider` and `DiagnosticOutputSlot` have been rewritten
 * they are now independent, self-contained specialisations, layered on top

Overall, what might seem like a detour, was an important step towards
well-balanced structures and a better understanding of the Render Engine.

<ul>
<li>
zun&#228;chst einmal war der BufferProvider selber zu koh&#228;siv, und hatte keine Innen-Struktur; insofern war es schwierig, konkrete Varianten durch Subclassing zu schaffen &#8212; wodurch es nahezu unm&#246;glich wurde, eine Proxy-Variante zu schaffen, die etwas anderes macht als &#187;point-and-shot&#171; direkt in ein Memory-Management
</li>
<li>
und zudem hing das Thema &#187;OutputSlot&#171; komplett in der Luft, und der DiagnosticOutputSlot war die einzige Implementierung, die sich mit vertretbarem Aufwand realisieren lie&#223;. Dieser erhebliche Aufwand hat mich unter Druck gesetzt, und deshalb habe ich die Arbeit abgek&#252;rzt, und direkt die Dummy-Implementierung des BufferProvider huckepack genommen (teilweise sogar am DiagnosticBufferProivder vorbei). Wegen dem ersten Problem aber konnte ich an der Stelle nicht direkt delegieren, und hab stattdessen neue API-Funktionen auf der DataSink geschaffen
</li>
</ul>
<p>
Insofern gab es <i>keine guten Gr&#252;nde</i>&#160;&#8212; aber ich hab's nicht besser hinbekommen damals, und ich hab die Bedeutung dieser Kongruenz auch noch nicht wirklich verstanden (weil die Engine nie soweit durchentwickelt worden war).

Dazu ist zweierlei festzustellen
</p>
<ul>
<li>
der OutputSlot verwendet nun ein BuffHandle als front-End f&#252;r das Protokoll. Das ist fest verdrahtet, und so bekommt es der user von der DataSink
</li>
<li>
allerdings <i>zur Implementierung</i>&#160;wird keinerlei Vorgabe mehr gemacht; tats&#228;chlich ist der OutputSlot nun komplett von der Implementierung des Output-Mechanismus <i>abstrahiert.</i>&#160;Stattdessen mu&#223; nun die <i>Implementierung des Interface OutputSlot::Connection</i>&#160;daf&#252;r sorgen, irgendwo eine Buffer-Addresse herzubekommen. Daf&#252;r kann sie, mu&#223; aber nicht, intern einen BufferProvider ansprechen

Der bestehende Stand der Entw&#252;rfe von 2012 war problematisch, und schwer zu greifen; es war eine z&#228;he und schwierige Aufgabe, das entstandene Geflecht systematisch auseinanderzunehmen. Als Ergebnis ist nun
</p>
<ul>
<li>
<i>im</i>&#160;BufferProvider eine Implementierungs-Struktur definiert, welche Metadaten (BufferStage) und Storage-Handling (BufferStore) sauber trennt und sparat erweiterbar macht
</li>
<li>
nach einem kompletten re-Design die Implementierung des OutputSlot generisch und mu&#223; nicht mehr durch Subclassing f&#252;r den jeweilgen Fall eingerichtet werden
</li>
<li>
die M&#246;glichkeit geschaffen, durch das Buffer-Handle als front-End die Protokoll-Schritte &#252;ber einen Proxy-Buffer-Provider durchzureichen
</li>
<li>
die Test/Diagnose-Implementierung in beiden F&#228;llen komplett neu geschrieben worden, und zwar als eigenst&#228;ndiger Layer oberhalb einer nun ebenfalls eigenst&#228;ndigen default-Implementierung
</li>
</ul>
<p>
Insgesamt habe ich nun den Eindruck, da&#223; dieses Design insgesamt eine Errungenschaft ist, und ich mich damit durchaus blicken lassen kann
