- refactor: move import_journal to hyperdb

.-- it was reimplemented in back_anydbm and rdbms_common and was
  already inconsistent -- and it doen't have any backend dependencies
  itself.  Interestingly this now fails a test for memorydb (but
  passes for anydbm: Huh?)

   Thanks to Benni B�rmann for reporting.
 - Allow search_popup macro to work with all db classes, issue2550567

-- lower memory footprint for (journal-) import -- only for rdbms
-  backends, other backends shouldn't have that much data anyway.
