change ranges in packed cands, fix trackvertex unpacker, commented code for covariance propagation to PCA
add hcal noise summary to the event content
Shower shape cleanup in electrons:
  * remove r9, sigmaIphiIphi from pat::Electron (in new releases it
    is already in reco::GsfElectron)
  * duplicate the 7.1.X interface of reco::GsfElectron from
    PR #3710 for the non-ZS ones, so that the 70X code will
    be forward-compatible with 71X
add setters to egamma objects to allow relinking to reduced collections for mini aod
add ReducedEGProducer for creating reduced collections of electrons and photons with consistently relinked clusters and conversions
adapt mini aod configs to use reducedEgamma collections
add function to clear detid vector for supercluster slimming in miniaod
restore slimming of internal electron and photon variables
add additional flexibility in relinking and restore previous mini aod behaviour of keeping supercluster and seed cluster for all output electrons and photons
Adapt ConversionTools to mini aod (work with embedded tracks and add loose matching for reduced conversion collection)
keep all LHE product independently of the module name
add ak4 reco and gen jets for 70X
Include reducedEgamma_cfi in slimming_cff
add unschedule mode option and add PAT step to cmsDriver
cmsdriver changes for pat
MiniAOD in cmsDriver for real (calling miniAOD_tools)

Conflicts:

PAT Tau relinking of references, and added universal accessors using CandPtr
parton match also to status 23 for pythia 8
Keep also status 22,23 and all top quarks
full5x5 shapes with foward-compatible interface also for photons
