use std::shared_ptr and std::make_shared (EventSetup in Reco)

[wmtan]

The only place that the CMS framework still uses boost::shared_ptr is in the interface to the EventSetup system, where std::shared_ptr is also supported. In order to remove this last vestige of boost::shared_ptr,
users of EventSetup need to be converted to std::shared_ptr. This PR does this for Reco packages.
Also, std::make_shared is implemented where it makes sense, because it simplifies the code and saves a memory allocation.
Packages TrackingTools/Gsf* are not done in this PR because there is another PR from Vincenzo Innocente making some of the same changes, and I wish to avoid a confluct with that PR.
This PR is totally technical.

@cmsbuild please test

The tests are being triggered in jenkins.

[VinInn]

@wmtan are you planning to migrate all other usage of boost to std?
there is a boost::shared_ptr<const TrajectorySeed> in Trajectory that I was going to migrate as part of some other algorithmic changes. If you are already on it I will not touch it.

[wmtan]

@VinInn No, I was just migrating those uses that were needed for removing support for boost::shared_ptr in EventSetup. This PR does all of those in Reco except for those in TrackingTools/Gsf*. I did not do those because I saw that your existing PR touches some of the same lines.

Please merge all these PRs involving shared_ptr asap: they touch almost everything, difficult to develop w/o risking conflicts...

For #13898 b7ba4b0

Purely technical change to eliminate boost::shared_ptr, replacing it with std:shared_ptr. There should be no change in monitored quantities.

The code changes are satisfactory, and Jenkins tests against baseline CMSSW_8_1_X_2016-04-02-1100 show no significant differences, as expected.

This pull request is fully signed and it will be integrated in one of the next CMSSW_8_1_X IBs (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @slava77, @davidlange6, @Degano, @smuzaffar
