Add code to actually use the sqlite_stat2.cnt field in the query planner. This changes some plans resulting in a few failures in analyze5.test. (Closed-Leaf check-in: d1248165 user: drh tags: query-planner-tweaks)

The sqlite_stat2.cnt field is parsed if it is present. But it is not yet used. A large comment added to analyze.c to explain the format of the ANALYZE system tables. (check-in: 6d1e2372 user: drh tags: query-planner-tweaks)

Merge together the fork in the query-planner-tweaks branch. (check-in: 2daab6bd user: drh tags: query-planner-tweaks)

Fix a compiler warning when STAT2 is off. More test cases. Fix legacy tests to deal with the new STAT2 logic. (check-in: 7e914aa9 user: drh tags: query-planner-tweaks)

Bug fixes to the sample-count logic for STAT2. A few test cases added. (check-in: e93c248c user: drh tags: query-planner-tweaks)

Add a column to the sqlite_stat2 table that contains the number of entries with exactly the same key as the sample. We do not yet do anything with this extra value. Some tests in analyze2.test are failing. (check-in: eb434228 user: drh tags: query-planner-tweaks)
