change ranges in packed cands, fix trackvertex unpacker, commented code for covariance propagation to PCA
add hcal noise summary to the event content
Cleanup of shower shapes in pat::Electron:

  * remove r9, sigmaIphiIphi from pat::Electron (in new releases it
    is already in reco::GsfElectron)
  * follow naming convention of PR #3710 for the non-ZS ones
Adapt ConversionTools to mini aod (work with embedded tracks and add loose matching for reduced conversion collection)
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
remove include for deprecated header
adapt to conversion changes in 71x
MiniAOD in cmsDriver for real (calling miniAOD_tools)
Depends on #3545 (queued) and #3543 (already merged)

Include reducedEgamma_cfi in slimming_cff
PAT Tau relinking of references, and added universal accessors using CandPtr
keep all LHE product independently of the module name
Make sure we run on AK4 jets (default seems to be still AK5).
Use AK5PFCHS corrections while waiting for a new GT
parton match also to status 23 for pythia 8
Keep also status 22,23 and all top quarks
FwdRef and FwdPtr: Nullness and Availability are two different things
