stringutil: emit multiple chunks when pretty printing
This avoids concatenating output inside pprintgen() itself. But
the real reason for this is it will make it easier to add
indentation, as we'll need to account for indentation when emitting
each individual object in a collection.
The verbosity of this code compared to the original is a bit
unfortunate. But I suppose this is the price to pay for having
nice things (streaming and indenting).
We could probably abstract the "print a collection" bits into a
generic function to avoid some duplication. But I'm not
overly inclined to do this.

Ensure debuild doesn't run the testsuite, as that could get silly.

We check debian package contents with portable tools so that when
we're on non-debian machines we can still test the packages that are
built using docker.
