More CINT removal cleanups:
- configure: remove enable_cling and hascling as we always have cling.
- remove many R__HAS_CLING ifdef's from the code.

From Gabriel:
Hide CINT interfaces (void* function pointers) from ROOT-with-cling; they were using Getp2f2funcname() and are not needed anymore.

Re-implement GetMinimum of TF2 and TF3 using the Minimizer class
- Add also GetMinimum/GetMaximum and TF2::GetMaximumXY and TF3::GetMaximumXYZ
- The functions TF2::GetMinimumXY and TF3::GetMinimumXYZ return now the minimum of the function

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.

The functions DrawDerivative and DrawIntegral return now a TObject* instead of being void.
In case of TF1 these functions return a TGraph*. This changes leaves the door open for a concrete implementations
in TF2 and TF3 with TGraph2D (may be) or a future TGraph3D.

from Axel:
Change the signature of SavePrimitive from
void SavePrimitive(ofstream &out, Option_t *option);
to
void SavePrimitive(ostream &out, Option_t *option = "");
With this change one can do, eg
myhist.SavePrimitive(std::cout);
WARNING: do rm -f tree/src/*.o

From Anna:
Implement new functions in TF2 and TF3 to find the minimum of a function.
void TF2::GetMinimumXY(Double_t &x, Double_t &y)
{
// return the X and Y values corresponding to the minimum value of the function
// To find the minimum on a range, first set this range via the SetRange function
// Method:
// First, a grid search is performed to find the initial estimate of the
// minimum location. The range of the function is divided into fNpx and fNpy
// sub-ranges. If the function is "good"(or "bad"), these values can be changed
// by SetNpx and SetNpy functions
// Then, Minuit minimization is used with starting values found by the grid search
void TF3::GetMinimumXYZ(Double_t &x, Double_t &y, Double_t &z)
{
// Return the X, Y and Z values corresponding to the minimum value of the function
// on its range. To find the minimum on a subrange, use the SetRange() function first.
// Method:
// First, a grid search is performed to find the initial estimate of the
// minimum location. The range of the function is divided
// into fNpx,fNpy and fNpz sub-ranges. If the function is "good"(or "bad"),
// these values can be changed by SetNpx(), SetNpy() and SetNpz() functions.

From Philippe:
The following patch implements TTree variable alias.
To use them:
mytree->SetAlias("mult","fPx*fPy");
mytree->Draw("mult");
Note that the aliases have been added to the TTree object so that they can be persistent (with the tree) if you choose.
Also note that the alias are not checked for validity until they are used in a Draw or Scan command.
Existing alias are silently replaced.
The new functions are:
TTree::SetAlias
TTree::GetAlias
TChain::GetAlias
TTree::GetListOfAliases
This patch also adds operator= for TFormula, TF1, TF2, TF3 (it calls the respective Copy member functions). It makes TTreeFormula::operator= private (Copy has not been implemented yet).
Also some of the TFormula and TTreeFormula codes (those stored in fOper) has been aliased to enums (this renders the code is little bit more readable and searchable).
TFormula and TTreeFormula have been updated to handle strings in a more flexible (and for TTreeFormula to be able to return them).

mega patch to remove almost all compiler warnings on MacOS X where the
compiler is by default in pedantic mode (LHCb also like to use this option).
The following issues have been fixed:
- removal of unused arguments
- comparison between signed and unsigned integers
- not calling of base class copy ctor in copy ctor's
To be done, the TGeo classes where we get still many hundred warnings of
the above nature. List forwarded to Andrei.

A patch by Olivier Couet with the mods to get a TF3 object paint.
The mods include:
-TF3 painting
-TF3 color settings (including context menu)
-Clipping box
Example:
TF3 *fun3 = new TF3("fun3","sin(x*x+y*y+z*z-36)",-2,2,-2,2,-2,2);
fun3->Draw();

W A R N I N G !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
==================================================================
A very long list of changes in this pre-release of version 3.00.
We have modified the signature of many functions (in particular TObject)
to introduce more constness in the system.
You must change your code if your class derives from TObject and uses
one of the modified functions such as ls, Print, Compare, Hash, etc.
The modified functions in TObject have the following signature:
virtual TObject *Clone() const;
virtual Int_t Compare(const TObject *obj) const;
virtual void Delete(Option_t *option=""); // *MENU*
virtual void DrawClass() const; // *MENU*
virtual void DrawClone(Option_t *option="") const; // *MENU*
virtual void Dump() const; // *MENU*
virtual TObject *FindObject(const TObject *obj) const;
virtual char *GetObjectInfo(Int_t px, Int_t py) const;
virtual ULong_t Hash() const;
virtual void Inspect() const; // *MENU*
virtual Bool_t IsEqual(const TObject *obj) const;
virtual void ls(Option_t *option="") const;
virtual void Print(Option_t *option="") const;
A similar operation has been done with classes such as TH1, TVirtualPad,
TTree, etc.

Double_t ymax=1, Double_t zmin=0, Double_t zmax=1);
