Parents and children of check-in [207335fd]

Get rid of the special RowSet processing in where.c and move that into clients. Added the WHERE_DUPLICATES_OK option to eliminate an unnecessary RowSet during DELETE with a WHERE clause containing ORs. (CVS 6546) check-in: 98606bee user: drh tags: trunk
Make sure that the optimizer realizes that an "x IS NULL" contraint does not necessarily give a single-row result even on a UNIQUE index. Ticket #3824. (CVS 6545) check-in: 207335fd user: drh tags: trunk
Make selecting the asynchronous IO file-locking mode a runtime operation. Still untested. (CVS 6544) check-in: 577277e8 user: danielk1977 tags: trunk
