Migration to 6x6 APE matrix in alignment and RECO

The pull request implements changes in a set of classes, plugins and configuration files necessary
for migration to the 6x6 APE matrix in the detector alignment and muon reconstruction parts of the CMSSW.
It affects the Alignment, Geometry, DataFormats and RecoMuon subsystems of CMSSW.

The previous relevant pull request is: https://github.com/cms-sw/cmssw/pull/6420
Large fraction of the changes in this PR are simply due to migration to the "extended" CondFormat.

Note: the new Global Tag with extended payloads is necessary for the PR to work, which is in "Pending" state at the moment
