	* Merge ISF_Services-00-08-00-branch into trunk (ATLASSIM-3029):
		* Adopt package to new location of Barcode.h and PhysicsProcessCode.h files
		(moved from BarcodeInterfaces package into new BarcodeEvent package). This is
		to follow ATLAS conventions about providing event-data types in dedicated
		*Event packages. ATLASSIM-2281
		* python/ISF_ServicesConfigDb.py - remove unneeded imports.
		Register CfgGetter method for ISF_ParticleKillerSvc. ATLASSIM-2995
		* python/ISF_ServicesConfig.py - add getParticleKillerSvc
		CfgGetter method. ATLASSIM-2995. General tidying of syntax.
		* Add support for pileup input collection to new
		ISF input processing implementation. Crucial for
		FastChain with pilup simulation. ATLASSIM-2928
		* python/ISF_ServicesConfigDb.py - remove no longer needed
		ISF_LongLivedParticleBrokerSvc configuration as it was made obsolete by
		ISF_LongLivedInputConverter. ATLASSIM-2928
		* Update long-lived particle simulation to new ISF input processing.
		ATLASSIM-2928
		* Refactor ISF Input Processing for AthenaMT. ATLASSIM-2928
		* Add first tests for new InputConverter AthService
	* ISF_Services-01-01-00
