Ingo Kegel 76dbbdfbf9 batch guid existence check on feed refresh ...

Instead of querying the database once per entry to check if it already
exists, fetch all existing guids for a feed in a single query upfront
and filter new entries in memory before the per-entry loop.

The per-entry findExisting call inside addEntry is kept as a safety net
for concurrent inserts, but is now only reached for new entries.

Profiling in real usage showed a ~50% reduction in guidHash queries,
with the check falling from the most expensive query to sixth in the ranking.
