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.

Rework TTree::ReadStream() / ReadFile(), mainly to fix delimited reading of string columns:
TLeaf::ReadValue() now takes an optional delimiter argument that is ignored for all but TLeafC. Here, input stops when reading this character, instead of at the first whitespace.
Use that in TTree::ReadStream() to delimit reading of TLeafC.
TTree::ReadStream() now tokenizes the row itself, and passes a stringstream containing nothing but the current column to TLeaf::ReadValue().
Improve error handling, improve debug output.
Clearly state which lines are skipped due to errors and why.
Fix windows files leaving '\n' in branch names when reading them from the file.
Separate concepts of number of input line (for communication with user) and number of good lines (as returned).
Simplify EOF-without-newline case.
Add error message for TLeaf::ReadValue(), i.e. if ReadValue() is called on a derived class that doesn't implement it.

The value of TBasket:;fBasket was incorrect in some cases when using
the TTreeCloner. This is solved (and thread safetly is improved) by
removing the gBranch global variable and using alternative mechanism
to set TBakset::fBasket.

Implement new function TTree::ReadFile
Long64_t TTree::ReadFile(const char *filename, const char *branchDescriptor)
{
// Create or simply read branches from filename
// if branchDescriptor = "" (default), it is assumed that the Tree descriptor
// is given in the first line of the file with a syntax like
// A/D:Table[2]/F:Ntracks/I:astring/s
// otherwise branchDescriptor must be specified with the above syntax.
//
// A TBranch object is created for each variable in the expression.
// The total number of rows read from the file is returned.
TNtuple::ReadFile has been modified to be consistent with TTree::ReadFile.
New function TLeaf::ReadValue implemented (and in all TLeaf derived classes).

From Philippe:
TLeafC was forgetting about its place holder if it encounters an empty string. This is never recovered from! (i.e. the address stays null and nobody checks or change
it).
This patch correct the situation for simply making the string of null length.

Remove a limitation in TLeafC::FillBasket and TLeafC::ReadBasket.
A maximum of 255 characters could only be written/read.
To be back compatible and still have minimal overhead, the following
algorithm has been implemented.
If the length of the string to be written is less than 255 bytes,
we use the old agorithm.
If more or equal 255 characters, we write the constant 255 followed
by the real length of the long string in integer format.
Thanks to Markus Frank for noticing/reporting the problem.

In the SetAddress functions remove the computation of fNdata.
fNdata is already computed in TLeaf::ResetAddress and must not be
recomputed at this point. This solves a long standing problem
with memory corrupted, specially when running without libNew.

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.

Enhancement of the automatic split mode by Philippe canal.
Variable length arrays are now supported.
The array has to be declared as:
Int_t myindex;
Int_t *myarray; //[myindex]
This also enables support for variable length C-style string:
char *mystring;
The mods make sure that MakeClass produces the correct code in this case.
