Multilink fixes and optimizations:
- Optimisation: Late evaluation of Multilinks (only in rdbms backends):
previously we materialized each multilink in a Node -- this creates an
SQL query for each multilink (e.g. 'files' and 'messages' for each
line in the issue index display) -- even if the multilinks aren't
displayed. Now we compute multilinks only if they're accessed (and
keep them cached).
- Add a filter_iter similar to the existing filter call. This feature is
considered experimental. This is currently not used in the
web-interface but passes all tests for the filter call except sorting
by Multilinks (which isn't supported by SQL and isn't a sane concept
anyway). When using filter_iter instead of filter this saves a *lot*
of SQL queries: Filter returns only the IDs of Nodes in the database,
the additional content of a Node has to be fetched in a separate SQL
call. The new filter_iter also returns the IDs of Nodes (one by one,
it's an iterator) but pre-seeds the cache with the content of the
Node. The information needed for seeding the cache is retrieved in the
same SQL query as the ids.
