7d44b22d45 Fix test cases so that they all still work even with -DSQLITE_DQS=0.

8efc6a8c09 When the result of a subquery is to be stored in a register and that 
subquery has an ORDER BY clause and an OFFSET, NULL out the destination
register before starting the ORDER BY so that the register will be set
correctly even if the OFFSET is larger than the number of output rows.
Fix for the problem reported in
[forum:/forumpost/0ec80f12d02acb3f|forum post 0ec80f12d02acb3f].

dfb5e1cbc6 Make sure the datatype and collating sequence of transients tables are 
not initialized more than once.  Otherwise a memory leak results.

165674d8db Fix test cases so that they work when the query planner uses index size 
estimates to determine whether or not to try an covering index scan.

78d1ef1a51 Add disabled test cases for ticket #2652. We will enable these test cases 
after #2652 is fixed.  The fix will be difficult and will probably take
a while.  On the other hand, correlated aggregate queries have never
worked in SQLite and the problem is just now coming to light, so it is
probably not a pressing issue. (CVS 4435)
