Clean up statics in CalibMuon/DTDigiSync.
Template migration and filter fix for Egamma
Make statics const in CondFormats/PhysicsToolsObjects
Remove unneeded statics.
Add a missing const.
Fixed non-const statics for DetectorDescription/Core
Removed use of UpdaterService from CachingVariable

The service UpdaterService can not work in the threaded framework. Therefore UpdaterService was removed from CachingVariable. In its place the CachingVariable uses the new cacheIdentifier of edm::Event to know if a new Event is being used.
Fixes -- tested on 6x and 7x releases.
Fixes for osx.
