Invocation: implement and verify extended verification

Browse source 
Since each `TestFrame` now has a metadata header,
we can store an additional data checksum there,
so that it is now possible both to detect if data
is in pristine state, or if it matches a changed state
recorded in the additional checksum.

So we have now three different levels of verification
 isSane:: consistent metadata header found
 isValid:: metadata header found and checksum there matches data
 isPristine:: in addition, the data is exactly as generated from the `(frameNr,family)`

/** @file testframe.cpp
** Implementation of fake data frames to support unit testing
** Implementation of fake data frames to support unit testing.
** The data generation is based on a _discriminator seed value,_
** which is computed as a linear combination of a statically fixed anchor-seed
** combined with the family-number and sequence number. Based on this seed,
** the contents are then filled by a pseudo-random sequence.
** @note while initially drawn from real entropy, the anchor-seed can be
** reset from the default PRNG, which allows to establish a totally
** deterministically setup from test code, because the test itself
** can seed the default PRNG and thus establish a reproducible state.
**
** Additionally, beyond this basic test-data feature, the contents can be
** manipulated freely, and a new checksum can be stored in the metadata,
** which allows to build pseudo media computation functions with a
** reproducible effect — so that the proper invocation of several
** computation steps invoked deep down in the render engine can
** be verified after completing a test invocation.
