50b6568454 Add tests to double-check that nothing within SQLite ever tries to allocate 
amounts of memory that are close to the maximum signed integer, leading to
an integer overflow within malloc().  This is not currently a problem.
The extra tests just insure it never becomes a problem. (CVS 6298)
