Most of them where useless, or only to call DQMStore::save().
That might be useful, but we really don't like people doing that so I removed them.

In a few cases modules were migrated to DQMOneEDAnalyzer because they had nontrivial logic in the beginJOb/endJob.
That logic is most likely broken either ways, but like this it at least still compiles.

I assumed the edm::stream instances would have independent module IDs,
but they don't, so we need to explcitly mix in the stream ID.

For now, DQMEDAnalyzer does not allow changing stream ids, but it would
probably work fine even if beginStream is called multiple times.

These were showing significant differences when running with multiple streams.
