commonality between those to functions. This is intended to help make the
code easier to read and maintain.

a corrupt database. Adjust the assert() and add a testcase() to make this
point clear.

circular references in triggers on virtual table shadow tables from causing
resource leaks.

corrupt, the code that restores the cursor position may overread the buffer by a
little.

of subquery that is being incorporated into the outer query - copies it
directly. This is more efficient. And it also fixes the specific test case
show for ticket [f09fcd17810f65f71789525] but it does not resolve the more
general problem that sqlite3ExprDup() does not correctly duplicate expressions
that contain subqueries with window functions.
