a1f7c0a21c Enhance the sqlite3VdbeRecordCompare() routines so that if they encounter 
database corruption, they will set the UnpackedRecord.isCorrupt field and
return 0.  The sqlite3BtreeMovetoUnpacked() routine detects this and returns
SQLITE_CORRUPT, causing the corruption to be reported back to the top-level.
