d11e397b2c Updates to fts5 to support detail=none mode. As of this commit, many cases are still broken.

9f44deed93 Change the name of the offsets=0 option to "detail=column". Have the xInst, xPhraseFirst and other API functions work by parsing the original text for detail=column tables.

b12dc84fbb Add the "offsets=0" option to fts5, to create a smaller index without term offset information. A few things are currently broken on this branch.

4591334dd4 Change to storing all keys in a single merge-tree structure instead of one main structure and a separate one for each prefix index. This is a file-format change. Also introduce a mechanism for managing file-format changes.

56e2497aaa Improve fts5 integrity-check so that it checks that DESC queries return the same as ASC. Change the poslist format slightly to make room for a delete-flag.

6f876c339d Fix the bm25() function so that it multiplies scores by -1 before returning them. This means better matches have a lower numerical score, so "ORDER BY rank" (not "ORDER BY rank DESC") does what you want.

8ac3025419 Have fts5 store rowids in ascending order. Query speed is virtually the same regardless of rowid order, and ascending order makes some insert optimizations easier.
