The changes outside the framework are the minimal adaption to this change.

Hi,

I took these changes on top of CMSSW_7_0_X_2013-08-19-0200, I ran the unit tests and RelVals, all tests passed.

I would request that the DQM signature be bypassed if it is not signed in a timely manner, say by tomorrow (Tuesday) morning. The DQM code involved was written by Chris Jones, not DQM people, and the change is trivial, and is the minimum necessary for compilation.
Also, this is in the critical path for the multithreaded framework, and another pull request that should be ready to be done today is dependent on this request. Of course, the new request could go in before this one is merged, but then the topic collector would indicate that the new request needs all the same signatures from this request, which is not the case.

Billl, thanks for the explanations. I've bypassed the signature.
