Cabal's Distribution.Utils.LogProgress module failed to take into
account whether we are marking output or not, and simply never included
output markers.
We also make sure that warnings go to stderr not stdout, to be
consistent with `Distribution.Simple.Utils.warnMessage`.
In summary, the impact is that:
- warning messages now consistently go to stderr
- when running the testsuite, we are more consistent in tagging
messages emitted by Cabal, with the 'BEGIN CABAL OUTPUT'/'END CABAL OUTPUT'
markers.
