45163fc45e Add an sqlite3_db_config() option - SQLITE_DBCONFIG_STMT_SCANSTATS - for enabling and disabling the collection of sqlite3_stmt_scanstats() statistics in SQLITE_ENABLE_STMT_SCANSTATUS builds. Collection of statistics is disabled by default.

4990fc84f1 Only use a Bloom filter on an automatic index if one or more of the key 
columns in the index can take on non-TEXT values.

a353369f57 In the Bloom filter optimization, hash all strings and blobs into the same 
value, because we do not know if two different strings might compare equal
even if they have different byte sequences, due to collating functions.
Formerly, the hash of a string or blob was just its length.  This could
all be improved.  Fix for the issue reported by
[forum:/forumpost/0846211821|forum post 0846211821].
