Ichthyostega 1df77cc4ff Library: investigate and fix an insidious problem with move-forwarding (util::join / transformIter)
As it turned out, we had two bugs luring in the code base,
with the happy result of one cancelling out the adverse effects of the other

:-D

 - a mistake in the invocation of the Itertools (transform, filter,...)
   caused them to move and consume any input passed by forwarding, instead
   of consuming only the RValue references.
 - but util::join did an extraneous copy on its data source, meaning that
   in all relevant cases where a *copy* got passed into the Itertools,
   only that spurious temporary was consumed by Bug #1.

(Note that most usages of Itertools rely on RValues anyway, since the whole
point of Itertools is to write concise in-line transformation pipelines...)

*** Added additional testcode to prove util::stringify() behaves correct
    now in all cases.
