--------------------------------
    Attachment: LUCENE-8007.patch

Adrien i brought the patch up to speed, fixed codecs to return {{totalTermFreq=docFreq}} and {{sumTotalTermFreq=sumDocFreq}} in DOCS_ONLY cases, and tried to remove all the damage caused by -1 values in code/javadocs/checkindex/tests/etc.

> Javadocs allow codecs to not store some index statistics. Given discussion that occurred on LUCENE-4100, this was mostly implemented this way to support pre-flex codecs. We should now require that all codecs store these statistics.
