An generic approach to merge values into a database. It is comparing
two ranges. The first range is the Sqlite select range and the second
one which are the new values. New values are inserted, change are
updated and missing values are removed. Unchanged values are not
touched. The compare function is comparing a key. Both ranges are
binary ordered.
