6fa978dade Futher simplifications to the NGQP. Fix some test cases to use 
EXPLAIN QUERY PLAN rather than the (now obsolete) sqlite_query_plan
global variable.

e8601c6561 Fix a bug in SQLITE_TRACE_SIZE_LIMIT that was introduced by 
check-in [1a1cf5aa86734c8].  That check-in was to remove harmless
compiler warnings.  So once again, we have introduced a real bug
into SQLite by attempting to eliminate a harmless compiler warning.
