26d7e7c6b7 Fix a problem in the block-sort logic that can arise if the VDBE opcode 
array is resized while the block-sort logic is being coded.  "make test"
now runs to completion, though there are still 17 failures.

079a307259 First attempt at getting block-sort to work. This is an incremental check-in. 
There are many problems still to be worked out.

d2de861cbe Adjust the query planner to keep track of the number of ORDER BY terms 
satisfied.  Still doesn't do anything with this information.  Some tests
fail after this check-in, but all failures are believed to be benign.  The
failures will be addressed at a later stage.
