Remove
  using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.

Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.

Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

From Andrei:
new class TGeoIterPlugin. 
This is an ABC for user plugins that need to call some arbitrary code during 
geometry hierarchy iteration. The first use case (requested in Savannah #57591)
is to dynamically change the color of volumes in selected paths, but not the 
color of the same volume in other paths. This use case is already implemented 
in TGeoPainter and an example of usage is given in the tutorials files 
$ROOTSYS/tutorials/geom/iterplugin.cxx and runplugin.C.

From Andrei:
- Removed casting away constness in headers, and removed == and != between doubles in all geom code (Philippe's suggestion)
- Info messages suppressed now by the static TGeoManager::SetVerboseLevel(0). We should probably call this at the beginning of stressGeometry.cxx
- Fine tune in TGeoIntersection::DistFromInside() that solves inner boundary crossings in case the starting point is very close to boundary
- TGeoManager::FindInCluster() gives now priority (when selecting between MANY candidates) to the node that was proposed by 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

Set property svn:eol-style LF on all source and Makefiles. This should avoid
problems with Win32 line endings ending up in the repository. All MS tools
support LF eols fine.

to
  void SavePrimitive(ostream &out, Option_t *option = "");

With this change one can do, eg
   myhist.SavePrimitive(std::cout);

From Federico Carminati:

"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

From Andrei:
 implementation of a geometry iterator (TGeoIterator) with a
detail description in the source file (TGeoNode.cxx). Multi-purpose usage,
but it is intended for being able to check overlaps between assemblies and
also to decouple TGeoPainter from TGeoManager.

From Andrei:
1. TGeoManager::SetNodeSelectable(flag); - allows user to make nodes selected in the
pad rather that volumes(default)
2. TGeoManager::ReplaceVolume(TGeoVolume *vorig, TGeoVolume *vnew); - allows
replacement of all occurances of VORIG with VNEW in the geometry tree. VORIG is not
removed from the list of volumes, but all nodes referencing it as their volume or
mother will reference instead VNEW.
3. static TGeoVolumeAssembly::MakeAssemblyFromVolume(TGeoVolume *vorig); - creates a
sort of clone of a normal volume (same daughters inside), but this will be an
assembly. This method can be used togeather with ReplaceVolume() to change some
virtual conainers in a closed geometry with assemblies.
4. TGeoVolume::RemoveNode(TGeoNode *node) - will safely remove a daughter node of a
volume, even if the geometry is closed. Geometry is valid for navigation afterwards.

From Richard Maunder:

Changes to viewer infrastructure (TBuffer3D,TVirtualViewer3D) to
support:

i) Proper shape specific (sphere, tube, etc) descriptions in TBuffer3D
derived classes - c.f. abuse of raw tesselation blocks before.
ii) On demand filling of buffer sections as required by viewer.
iii) Support for local/master frame shapes descriptions & child object
rejection.
iv) Template/placed shapes ids - enabling viewer to detect/receive
common shapes once and just obtain the new position and id of the
duplicate.

Cleans up all producer (g3d/geom) code so no longer has an viewer
specific knowledge - Paint() methods replaced with
GetBuffer3D/FillBuffer3D methods which complete requested sections of
the buffer.

All viewer specific code now sits on the viewer implementation side of
TVirtualViewer3D. Added a TViewer3DPad class for performing the 3D draws
into pad. In future this should be merged with TView/TView3D possibly.

TBuffer3D is now stripped of functional code (aside from memory
management) and various viewer passback options there previously.
Enforced one way passing a const & to viewer.

Buffers (various types) are held as single static inside producer
function e.g. TGeoShape::GetBuffer3D (c.f. single generic buffer type
fetched from pad previously).

For g3d and geom shapes the top level geometry painter (TNode /
TGeoPainter) controlls painting process, requesting shapes to fill
buffer and passing to 3D viewer.

Exceptions are g3d's TPolyLine3D, TPolyMarker3D & TMarker3DBox. These
are 'standalone' shapes - no controlling 'painter' object. They still
implement Paint(), fill buffer and add to viewer directly.

3D viewer still held / created by pad - and pad has it's own viewer
object (TViewer3DPad).

NOTE:

1. Current scheme supports one 3D viewer only - pad, x3d or OpenGL. This
means that pad goes blank when x3d/OGL is spawned, and is updated again
when it is closed. To be revisited - need to support multiple viewers,
of multiple types - which implies explicit naming or pad controlling
enumeration.

2. OGL viewer now responds correct to modifications in pad, without
having to be reinvoked (as previously). x3d is still decoupled (as
previously) so does not rebuild - too difficult to get working.

Several updates to the geometry pacjage by Andrei:
TGeoManager :
- added getter for current direction;
- dummy cache option by default
TGeoNodeOffset
- set the name for parametrized divisions; minor fix in allocating the
space for the name (safer now)
TGeoPatternFinder :
- the getter for the matrix of a divided node will return the updated
matrix (before one had to do TGeoNodeOffset::cd() first, now
TGeoNodeOffset::GetMatrix() does this in one go)
Shape classes :
- protection for wrong division range slightly modified

Upgrade of the geom classes by Andrei:
- improvements in the drawing mechanism (nodes can also be made
invisible, having higher priority than volumes;
- possibility of simple phi cut in TGeoManager::SetPhiRange(phimin, phimax)
  - by default the phi range is (0, 360) - no cut performed
 - setting different values for phimin, phimax will make invisible the
nodes having the origin in this range;

- documentation updated for TGeoArb8 class (picture in /gif directory)

new version of the geometry package from Andrei:
- bug fix in the destructor of TGeoPatternCylPhi
- several modifications in the default constructors of shapes.
- several corrections and "v" feature added to I/O
- removed base class for finders

 Now you can save voxels and retreive them with no problem. You can use :
  gGeoManager->Export("filename", "", "v") to do that. The size of files
without/with voxelization are :
    Exp           no voxels saved             voxels saved
ALICE            404227                        719703
CMS               550440                       1275590
ATLAS         1858198                      3335166

Be careful, the files TGeoFinder.h and TGeoFinder.cxx have been removed.
Suggest doing:

rm geom/src/*.o geom/src/G__*

A few changes in several classes in order to restore a TGeoManager.

Implement two new functions in TGeoManager
Int_t TGeoManager::Export(const char *filename, const char *name, Option_t *option)
{
   // Export this geometry on filename with a key=name
   // By default the geometry is saved without the voxelisation info.
   // Use option 'v" to save the voxelisation info.

TGeoManager *TGeoManager::Import(const char *filename, const char *name, Option_t *option)
{
   //static function
   //Import in memory from filename the geometry with key=name.
   //if name="" (default), the first TGeoManager object in the file is returned.
   //Note that this function deletes the current gGeoManager (if one)
   //before importing the new object.

New version of the geometry package by Andrea & Mihaela Gheata
New features:
 -I/O for all geometry classes. For example, to save/restore a geometry structure,
   TFile f("mygeom.root","recreate");
   gGeoManager->Write("mygeom");
  and to read it back;
   TFile f("mygeom.root");
   f.Get("myGeom");
   gGeoManager->CloseGeometry();

 -Composite shapes fully implemented (no visualisation yet).
  A composite shape is built out of basic shapes and transformations via
  a simple formula mechanism, eg assuming a TGeoTube "tub1" and a TGeoMatrix "r1",
  we can build a composite shape with:
    TGeoCompositeShape *comp = new TGeoCompositeShape("comp",formula); where
    char* formula="tub1+tub1:r1"
  This will create the union of a tube with itself rotated.
  The operators recognized by the geometry formula parser are "+","-","*"
  for union, subtraction and intersection respectively. The colon ":" can be
  used to specify a transformation for a given component.

 -The voxelisation in cylindrical coordinates added as an optional optimisation
  algorithm.

 -Some bug fixes and several improvements in the tracking-related algorithms.
