d4e70ebd6f Begin setting a foundation on which to convert the VM from a stack-based 
to a register-based machine.  Everything is still mostly stack based with
this check-in.  This change merely begins adding infrastructure to support
a register-based architecture. (CVS 4652)

recording malloc failures.  This eliminates the need to pass sqlite3*
pointers into many internal interfaces.  Also added more mutexing. (CVS 4263)

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)
