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.

CVs been changed into a pure abstract interface.
The concrete implementation is in the new class TBufferFile.
All classes previously deriving from TBuffer derive now from TBufferFile, ie
TBuffer <- TBufferFile <- TMessage
<- TBufferXML
<- TBufferSQL
<- TBufferSQL2
Because there are several problems with C++ operators overloading,
The I/O operators are defined in TBuffer. These are inline functions
calling C++ virtual functions defined in TBuffer and overloaded
by TBufferFile and all other derived classes when necessary.
The previous implementation of TBuffer.h included <vector> and Bytes.h.
The two include statements have been moved to TBufferFile.h. As a result the
compilation of the ROOT system is now slightly faster and a big bonus
is that changes in TBufferFile or Bytes.h will affect only TBufferFile
and will not force the recompilation of the entire system.
This change has some side-effects. If you assumed that include <vector>
was done by TBuffer.h, you may have to specify this include directly
in your class. This was the case for a few ROOT classes.

Extension of TBits by Filip Pizlo <pizlo@purdue.edu>
New getters/setters:
//----- Optimized setters
// Each of these will replace the contents of the receiver with the bitvector
// in the parameter array. The number of bits is changed to nbits. If nbits
// is smaller than fNbits, the receiver will NOT be compacted.
void Set(UInt_t nbits, const Char_t *array);
void Set(UInt_t nbits, const UChar_t *array) { Set(nbits, (const Char_t*)array); }
void Set(UInt_t nbits, const Short_t *array);
void Set(UInt_t nbits, const UShort_t *array) { Set(nbits, (const Short_t*)array); }
void Set(UInt_t nbits, const Int_t *array);
void Set(UInt_t nbits, const UInt_t *array) { Set(nbits, (const Int_t*)array); }
void Set(UInt_t nbits, const Long64_t *array);
void Set(UInt_t nbits, const ULong64_t *array) { Set(nbits, (const Long64_t*)array); }
//----- Optimized getters
// Each of these will replace the contents of the parameter array with the
// bits in the receiver. The parameter array must be large enough to hold
// all of the bits in the receiver.
// Note on semantics: any bits in the parameter array that go beyond the
// number of the bits in the receiver will have an unspecified value. For
// example, if you call Get(Int*) with an array of one integer and the TBits
// object has less than 32 bits, then the remaining bits in the integer will
// have an unspecified value.
void Get(Char_t *array) const;
void Get(UChar_t *array) const { Get((Char_t*)array); }
void Get(Short_t *array) const;
void Get(UShort_t *array) const { Get((Short_t*)array); }
void Get(Int_t *array) const;
void Get(UInt_t *array) const { Get((Int_t*)array); }
void Get(Long64_t *array) const;
void Get(ULong64_t *array) const { Get((Long64_t*)array); }
New test program testbits in the test directory.

Several changes in class TBits.
- Make all getters const
- rewrite function CountBits (8 times faster than previous version)
- implement two new functions
UInt_t FirstBitNull() const;
UInt_t FirstBitSet() const;

New version of TTreeFormula/TFormula by Philippe Canal:
In a TFormula . and -> are now synonymous.
In a TTreeFormula, you can now specify the index of an array (TClonesArray
or regular array) via another expression of the variable of the tree.
For example the following are now correctly handled:
myTree->Draw("clone1.a1:clone2.a2[2]");
myTree->Draw("clone1.a1:clone2.a2[clone1.b1]");
myTree->Draw("clone1.a1","clone2.a2[clone1.b1]>0");
This patch also enable (rudimentarily for now) the access to data members.
So now both the following are possible:
T->Draw("event->GetNtrack()");
T->Draw("event.fNtrack");
The lookup of leafname has been improved so that whether of not the dot
has been forced into the branchname the following will work:
T->Draw("event.fTemperature")
T->Draw("fTemperature")

New class TBits by Philippe canal
// TBits //
// //
// Container of bits //
// //
// This class provides a simple container of bits. //
// Each bit can be set and tested via the functions SetBitNumber and //
// TestBitNumber. . //
// The default value of all bits is kFALSE. //
