f127814eae Add the showstat4.exe utility program for decoding and displaying the 
content of the sqlite_stat4 table in a database.

c1971541e4 Add the .fullschema command to the sqlite3.exe utility. This command shows 
the schema and the content of the sqlite_stat tables, all in one go.  Useful
when reporting problems with the query planner.

62a223e5dd Modify the %nonassoc directive in lemon so that it generates a run-time 
error rather than a parsing conflict.  This changes is due to a bug report
on the mailing list.  SQLite does not use the %nonassoc directive in its
grammar so this change does not affect SQLite.

c94b2f7d6b Make sure the estLog() routine in the query planner handles negative
