Simplify the accumulator reset for aggregate query processing so that it uses a single multi-register OP_Null rather than a separate OP_Null for each register. check-in: 2c7fd9b0 user: drh tags: trunk

Make sure errors encountered while initializing extensions such as FTS4 get reported out from sqlite3_open(). This fixes a bug introduced by check-in [9d347f547e7ba9]. Also remove lots of forgotten "breakpoint" commands left in test scripts over the years. check-in: ca3fdfd4 user: drh tags: trunk
