Added thread id retrieval via TLS. Faster version of TGeoBranchArray. Added getters for specific activity (in Bq/gram) for radioactive elements and materials/mixtures via GetSpecificActivity().

Adding thread id as parameter to methods of TGeoVoxelFinder to avoid passing through the serial TGeoManager::ThreadId. This recovers quite good the scalability with the number of threads

From Andrei:
a tracking optimization patch, based on the new function TGeoNavigator::IsSafeStep(). This backs-up the last computed safety in correlation with the last point coordinates (safety sphere). When a new safety is asked during FindNextBoundary calls, it first checks if the safe sphere around the new point is included in the old one. If this is the case the function returns true and the navigator just approves the step. This avoids the expensive FindNextBoundary calls when the steps imposed by MC are very small.
Particularly efficient in large volumes in FLUKA simulations.

From Andrei:
- Truncation errors better taken into account when propagating to boundaries.
- A fix for TGeoXtru::DistFromInside() in case propagation to outside fails.
- A very important protection in TGeoArb8 that checks if the vertices are defined clockwise. It posts an error message if this is not the case and automatically fixes the wrong shapes event if geometry is loaded from file.

From Andrei:
While debugging the interfaces with G4/FLUKA, i found a couple of bugs related to TGeoNavigator::FindNextBoundaryAndStep(). One problem was affecting crossing boundaries within divided volumes (sometimes a step was made in the mother volume and few division cells were skipped). The other problem was wrongly returning the top node even if the point was correctly located.
Both problems are fixed by the patch. This will certainly improve the situation for the problems reported both with TFluka and g4root interfaces, as well as rare problems when computing the material budget in ALICE (reconstruction). Does not affect G3 navigation that works using FindNextBoundary()

From Andrei:
there was an implicit dependency of TGeoMatrix by TGeoManager.h via TGeoNavigator.h->TGeoCache.h + few other bad dependencies like: TGeoMatrix included by TGeoNode.h via TGeoPatternFinder.h Hmm... I had to cleanup few inlines, introduce a transient matrix in TGeoNavigator (to recover the lost inlining speed) + add several #include "TGeoMatrix.h" allover where this was included and used via TGeoManager.h

From Andrei & Mihaela:
I managed together with Mihaela to split out all navigation functionality out of TGeoManager into a new class TGeoNavigator (attached diff, .h and .cxx). The changes are fully backward compatible and did not require modifying the streamer of TGeoManager. We have tested with:
- /roottest/root/io/geo - the reference changes a bit (name of a class)
- aliroot with G3
- /test/stressGeometry
New feature: one has a default navigator for a geometry but may add several others for parallel navigation:
TGeoNavigator *navig = new TGeoNavigator(gGeoManager);
Int_t inav = gGeoManager->AddNavigator(navig);
gGeoManager->SetCurrentNavigator(inav);
.... and then switch back to the default navigator:
gGeoManager->SetCurrentNavigator(0);
One may also derive from TGeoNavigator and implement its own navigation (I doubt that this will ever happen but you never know...)
