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.

Reduce by 40% the time taken GetEntry for a branch created using a leaflist (exclusive of the decompression time).
Cache the current basket and its limit.
Reorder the set of test to reduce the number of conditional jump in the most common cases
and use:
#define unlikely(expr) __builtin_expect(!!(expr), 0)
#define likely(expr) __builtin_expect(!!(expr), 1)
to tell the compiler/processor which branch is more likely.
Record whether the buffer's map of classname and object is used to avoid resetting unnecessarily at read time.

Apply revision 18817 to all TLeaf:
In TLeaf?::ReadBasket one must check that fReadEntry in the count branch
is the same as the one in the branch being read.
This check is necessary when reading only one branch having a branch counter.

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:
This patch fixes a crash when trying to merge 2 tree which
already have a clone relationship.
More generally it protect cases where the new address being
set is already the existing address.

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.

Fix a complex problem in all TLeaf::SetAddress. The problem appears in situations
like the following:
a TChain of files is created with a TTree having branches with pointers
to basic types. In the first Tree, a branch has a maximum length of 50.
In the second Tree, the branch may have a longer length.
The solution is to systematically delete the array at the pointer address.
(Thanks to Eddy Offermann for providing a simple example)

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.
