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.
This form allows you to request diffs between any two revisions of this file.
For each of the two "sides" of the diff,
