Add module for validating tracks in miniAOD and fix track-to-PackedCandidate association

[makortel]

This PR adds a DQM module for comparing the tracks embedded in PackedCandidates to the corresponding generalTracks. The comparison is performed by filling a set of histograms from differences of several quantities that are expected to be equal within the numerical accuracy (two exceptions being "diffNdof" and "diffHitPatternNumberOfLostPixelHits", to be documented on some twiki page).

I also decided to include #9564 here since it is a prerequisite and its integration hasn't progressed yet. Without it the code would sooner or later throw an exception with

Exception Message:
Association: index in the map out of upper boundary

Tested in CMSSW_7_5_X_2015-06-06-2300 with wf 11325. No other changes expected than new histograms under "Tracking/PackedCandidate" folder.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_5_X IBs once checked with relvals in the development release cycle of CMSSW (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar
