b46ee91729 Allow the "order=DESC" and "order=ASC" parameters in FTS4 "CREATE VIRTUAL TABLE" statements. Tables created with "order=DESC" store all doclists in descending order, which allows optimizations normally applied to "ORDER BY docid ASC" queries to be used with "ORDER BY docid DESC" queries instead.
