Important BUG FIX in parameter assignment of millepede-based tracker alignment

[mschrode]

The bug corrupts the IOV-dependent alignment in releases compiled with
slc6_amd64_gcc472 and later. It is caused by using a dangling reference to
an edm::EventID object to determine the run number. At least with the gcc
versions in SLC6, this results in an incorrect determination of the current
IOV. Details are given in this presentation at the tracker-alignment meeting:

https://indico.cern.ch/event/342234/session/0/contribution/8/0/material/slides/0.pdf

The implementation is the outcome of a discussion of #6515 .

This PR supersedes #6518 .

@smuzaffar @cmsbuild : Would you mind proceeding with the tests? This PR is needed to create results that need to be approved. We should not use privately patched areas for such things. Kind regards, TkAlignment conveners.

This pull request is fully signed and it will be integrated in one of the next CMSSW_5_3_X IBs unless changes (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @smuzaffar, @ktf
