43617e9ab9 Code changes resulting from Coverity analysis. 
http://scan.coverity.com/  Found 1 potential segfault in sqlite3_mprintf().
Also 2 failures to fclose() following a malloc() failure.  And lots of
cases where unnecessary conditionals could be removed from the code. (CVS 3126)

0342b1f542 Sorting is now done using a sorting index rather than loading the entire 
result set into memory and doing a merge sort.  The old merge sort technique
was a carry-over from SQLite version 1.  The new method uses a bounded amount
of memory and scales to much larger result sets.  There are still errors:
some 39 regression tests fail. (CVS 2653)
