[36ce5494] part of check-in [1e17ea2f] Remove support for STAT3. The sqlite_stat3 tables are ignored, if they exist. STAT4 continues to work as it always has, and as it is a superset of STAT3 is the recommended replacement. (check-in: [1e17ea2f] user: drh branch: omit-stat3, size: 3685)

[e32a9705] part of check-in [dab5e529] More test case updates. Tests are all running now. (check-in: [dab5e529] user: drh branch: rework-EQP, size: 3693)

[c05a461d] part of check-in [2d36be5d] Change the query planner to do a better job of estimating the number rows selected by a BETWEEN operator using STAT4 when both upper and lower bounds are contained within the same sample. (check-in: [2d36be5d] user: drh branch: trunk, size: 3737)

[f3afd910] part of check-in [cca8bf43] If ENABLE_STAT3 is defined but ENABLE_STAT4 is not, have ANALYZE create and populate the sqlite_stat3 table instead of sqlite_stat4. (check-in: [cca8bf43] user: dan branch: sqlite_stat4, size: 3738)

[8d1f76ff] part of check-in [f783938e] Fix a bug in using stat4 data to estimate the number of rows selected by a range constraint. (check-in: [f783938e] user: dan branch: sqlite_stat4, size: 3730)

[8a9c83bf] part of check-in [6d1e2372] 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 branch: query-planner-tweaks, size: 4568)
