This PR gives a major update to the tracking MiniAOD validation code.

  • Compare only charged PackedCandidates
  • Check normalizedChi2 only if PackedCandidate ndof != 0
    • it it is 0, its normalizedChi2 is 0 by construction
  • Check hasValidHitInFirstPixelBarrel() only if there are no lost inner hits
    • if there are, this information is not valid
  • Record the number of tracks used in the two cases above in the selection flow histogram
  • Monitor the overflow of pixel hits, strip hits, and total number of hits
  • Add (LogInfo) printout for track-PackedCandidate pairs where differences are outside tolerances
    • Helps to track them down
  • Detailed monitoring of the precision of packed floating point values
    • Try to catch and monitor under/overflows and sign changes
    • Limit monitoring mainly to the packed quantities (e.g. prefer covariance matrix elements over the corresponding "errors"), but provide monitoring of most interesting quantities where "equality within packing precision" is not expected (e.g. pT)

Tested in CMSSW_8_0_X_2015-11-11-2300, expecting changes in Tracking/PackedCandidate DQM folder.

Created a helper class to monitor under/overflow of the packed
quantities (with specializations for float16 and liblogint). Limit
comparisons mainly to the exact quantities that are packed (e.g.
prefer covariances over errors), but compare also some "derived"
quantities when interesting. ("derived" = calculated from >= 1 packed
quantities)

I noticed only now that there was one unused function left (from which gcc warns), and one set of histograms had one extra bin.
