5f40cebf43 Fix problems in trigger and foreign key handling when doing REPLACE on a 
WITHOUT ROWID table that has no secondary indexes.

34d04d64f0 Ensure that the sqlite3_value_text() interface returns a buffer that is long 
enough to hold the complete string plus the zero terminator even when the
input is a zeroblob.  Fix for a problem detected by OSS-Fuzz.

801f55d837 Improved the comment on the block of code the provides the performance 
optimization originally added by check-in [925840cfdb].  The original
check-in omitted condition 4, which was the cause of bug [30027b613b].
