Add the sqlite3_vtab_collation() function, which allows an xBestIndex callback to determine the collation sequence that SQLite will use for a comparison. And the SQLITE_DBCONFIG_FULL_EQP configuration option, which enhances the output of "EXPLAIN QUERY PLAN" so that it includes statements run by triggers.
