LUCENE-1590: don't allow stored-only fields to mess up the index-only attrs like omitNorms and omitTermFreqAndPositions

public APIs to throw InterruptedException. (Jeremy Volkman vai
Mike McCandless)
9. LUCENE-1590: Fixed stored-only Field instances to not change the
value of omitNorms, omitTermFreqAndPositions in FieldInfo; when you
retrieve such fields they will now have omitNorms=true and
omitTermFreqAndPositions=false (though these values are unused).
(Uwe Schindler via Mike McCandless)
New features
1. LUCENE-1411: Added expert API to open an IndexWriter on a prior
