e46292a920 Improved rebustness in sqlite3ExprListDup() when it contains a vector assignment 
from an UPDATE where the initial term is omitted.  This can happen during a
UNION ALL query flattening while processing a virtual table update in which
the first term of the vector is repeated.

ba39ca4058 When deleting an SQL function that does not exist, return without doing 
anything at all rather than creating a tombstone function.  In this way,
function deletes that happen inside virtual-table destructors that are run
when a database connection is closing do not create new tombstones in the
function table after the function table has already been purged.

060b7fa974 Refactor the LIKE optimization decision logic so that it uses 
sqlite3AtoF() on both boundary keys to determine if the optimization can be

ff4fa772f5 Update error message text for standard error codes to better describe the 
latest usage of those error codes.  Modify sqlite3_open_v2() so that it does
return a valid sqlite3 object in the event of SQLITE_MISUSE due to bad
open flags, so that sqlite3_errmsg() does not report "out of memory" in that
case.
