Migration to 6x6 APE format needed for muon reconstruction

The branch implementing the changes in the CondFormat/DB table to accommodate the rotational APEs:

and the changes in the muon reco to propagate the APE in the fit.

* Expected physics changes: 
No physics changes is expected before muon APEs are enabled. In particular, no physics changes is expected from putting CondFormat + new error formats and transformations in.
If muon APEs are enabled, we expect improvement in the q/pT pull assignment, with parameters closer to N(0,1). Some improvement of q/pT momentum resolution at high pT is expected. See:

* Expected technical performance changes:
No significant effect on CPU performance, some increase of VSIZE and RSS with new code were observed. See:
