BufferProvider: propagate the actual buffer-size info

This is a nasty new requirement, discovered as an aside while looking
into ways to resolve the crucial mismatch between the OutputSlot
and BufferProvider, using the proxy-implementation of BufferProvider
(thereby expanding on the recent draft with the BufferProxyAdaptor)

The point is, if the BufferMetadata will be used beyond the internal coordination
within BufferProvider, then it will be used as part of actual buffer storage.
And this implies that the actual size of the allocation may differ (be greater)
than the nominally required size (since we'll very likely employ some kind
of memory tiling, for reasons of performance).

This leads again to an analysis of BufferMetadata usage,
with the conclusion to add the actual storage size directly into the API,
but treat it as an extra and not integrated into the buffer type

Phew ... quite complex alltogether
