5b4af26d7d boundarylayers sides with separate bcnr and option to set surface 
index to -1

this fixes 2 issues:

* If extruded outwards in occ and curvature turned on, if sides are
not set to index -1 then they are curved back towards the face again

* If no different facedescriptor is set, blayer.Boundaries() would
wrongly return the whole boundary and not only the layer part of the side.

47de18a508 Avoid loading geometry from mesh file twice 
Ng_LoadMesh() tries to read the geometry from the mesh file. If it was
read before by Mesh::Load(), the preloaded geometry is replaced by
ng_geometry (which might be garbage)

This is a mere workaround, not a clean solution (Mesh::Load() should
handle everything, including MPI distribution of geometry)
