From Ioan:
Replace the trunk code that uses the deprecated TH1::kCanRebin bit with
the new methods TH1::CanExtendAllAxes() and TH1::SetCanExtend() - see r47909,
r48012 and r48031. The old TH1::kCanRebin bit did not really have much to
do with histogram rebinning, but rather with extending the limits of the
histogram's axes (which can cause a rebin, but only in some cases). As such,
the word "Rebin" has been replaced with "Extend" for the new methods.
Rename TH1::RebinAxis() to TH1::ExtendAxis() for the reasons stated above.
The TH1::RebinAxis() method will be kept in v6-00 for backward compatibility
with an obsolete warning and will be removed in v6-02. The current
implementation simply forwards the call to TH1::ExtendAxis().

Several fixes in the draw functionality needed by a forthcoming tutorial:
- Allow to set a color, size, size, width for lines, area, markers; the
attributes are transmitted via the input list and automatically derived
from the ones of the chain
- Fix a problem with the axis ranges of the underlying histogram in PolyMarker3D
- Allow to use the default pad instead of forcing creation of one pad per object
- Add wrapper to handle the feedback default canvas

From Gerri:
- Fix a few problems found running in valgrind:
- In XrdROOTMgr::Validate, add missing protection against inproper use of a
temporary file when in non debug mode
- Fix a problem with inproper deletion of XrdProofWorker objects when working
with a dynamically varying 'proof.conf'
- In TProof::HandleInputMessage, fix possible double delete after kPROOF_STOPPROCESS
- Fix a couple of issues on reconnection to a running session:
- make sure that the dialog buttons are in the correct state
- make sure that logs are redirected
- Fix an issue with the displaying speed of very large log files (bufferize instead of
doing line-by-line)
- In TProof::Draw, change the type of a notification message from 'error' to 'debug'
- Fix coding conventions in TDataSetManagerFile.cxx

TProofDraw
- Do not try to get "htemp" from the input list; this removes a useless warning
TProofPlayer
- Improve the treatment of histogram merging in case of small statistics, i.e. when
the autobinning is not or only partially active. The largest stat histogram is
taken as base for the merging. This is implemented both for output and feedback
histograms, and avoids the large axis boundaries variations observed in such cases.

TProofDraw
- Fix a problem preventing drawing into an existing histogram, i.e. chain->Draw("var>>myhist"),
to work properly (chain->Draw("var>>hnew(nbin,xmin,xmax) was working fine).
- Add missing initialization (fTree in the basic constructor)
TProofPlayer
- Remove the relevant map in the list fFeedbackLists if the final object is available in the
output list; this prevents a duplication of the final feedback object
- Improve debug messages in StoreFeedback
TProofServ, TProof
- Fix a couple of memory leaks due to missing destruction of TProofProgressStatus objects

Change the TError.h macros:
Assert -> R__ASSERT
Check -> R__CHECK
Change the TCollection.h macro:
ForEach -> R__FOR_EACH
This to avoid potential problems due too trivial macro names.
The old macros will be removed in the next release. Currently
they will print out warning messages with the advice to move
to the new macro names.

Reduce direct dependencies on TClass.h, TROOT.h and TStreamerInfo.h.
Warning: This means that some file that relied on the indirect
inclusion of these header file might now fail to compile with
an error message mention that gROOT is no known or that TClass,
TROOT or TStreamerInfo is incompletely defined. Simply add the
proper include directive.

from Gerri:
- fix several issues with Begin() not being called when finalizing a query
done via TChain::Draw(), call setup code now also in Terminate().
- fix error with query progress dialog not finishing when analysing
subset of data set.
- add master and slave startup feedback code.
- fixes also a few additional problems with enabling/disabling of
Stop/Abort buttons and cleans up the treament of fOutputList in TQueryResult.
It is also make sure that there are no multiple copies of a TDSet in the
output list.

From Marek:
- TH1::Merge() adding overflows even when merging histograms with the
same limits. If the limits are different the overflows are ignored.
The same in TH2::Merge, TH3::Merge, TProfile::Merge and TProfile2D::Merge.
- Cleaning fHistogram (and this kind of) variables, so that the drawn
plots aren't deleted in the TProofDrawXXX's destructor.
- Removed TProofNTuple from TProofDrawTGraph.
- Put the initialization code of fFeedback and fPlayer (=MakePlayer())
in TProof in to Init().
- Added TGraph::Merge(). Added TPolyMarker3D::GetPoint(Int_t, Float&,
Float&, Float&).
- Removed TProofNTuple from TProofDrawPolyMarker3D.
- Fixed cleaning output lists after processing (set option = "nodelete").
Now the objects are on the player outputlist and are removed (but not
deleted) from the selector's outputlist.
- Fixed TPolyMarker3D::Merge() - it seems that nobody has ever tried to
run this function.
- Added setting tree attributes (like MarkerStyle, MarkerSize, LineColor etc.)
to a drawn TGraph and TPolyMarker3D in TProofDrawGraph and
TProofDrawPolyMarker3D.

From Marek Biskup:
major new PROOF developments:
- access to PROOF directly via the TChain interface (creating a TDSet
in the background).
- access to PROOF based trees via the TTreeViewer
- fully implemented the TChain/TDSet::Draw() interface.
- PROOF sessions can now be browsed via the TBrowser

From Philippe:
This patch solves a problem where the sizes of a collection
within a split-collection where not properly loaded (i.e.
TTreeFormula::LoadCurrentDim was not calling GetEntry on
the branch containing the collection within a collection).
Also (and independently):
To support for the cases where the user do
tree->GetEntry(entry);
// modify the event
tree->GetEntry(entry);
// User expect the event to have reverted to
// the same state as after the first GetEntry
we insured that TBranch::GetEntry always re-stream the
data from the basket. Similarly, TTreeFormula::EvalInstance
needs to also insure that it always re-stream the data
from the basket (Some developer uses TTreeFormula directly).
However in case, when we are guaranteed that the data pointed
to by the tree will not modified and we need to call GetEntry
several times on the same branch for the same entry,
this is a waste of time.
We are in this case for the TTreeFormula handled by
TProofDraw, TSelectorDraw and TTreeIndex.
The case where we currently have the inefficiencies are
the cases for the same branch is listed in several
distinct formulas (for example in the 1 dimension and
the selection or as an index) and the cases of
variable dimensions formulas (GetEntry called at least
once in LoadCurrentDim and once more in EvalInstance).
The attached patch solve the issue for TProofDraw,
TSelectorDraw and TTreeIndex by adding a new data member
to TTreeFormula (fQuickLoad), this can be set to tell
TTreeFormula to assume that the data is really read-only
(and hence it does not need to read the branch again is
br->GetReadEntry()==tree->GetReadEntry().
We can not solve the issue in the general case since we
can not guarantee that that data pointed will not be
modified between the call to GetNdata (hence LoadCurrentDim)
and EvalInstance. The cost of not properly insuring is
high since it involves silently displaying incorrect data.
However LoadCurrentDim could still be improved since it does
not use the optimization used by EvalInstance which insures
that itself reads each branch only once (Fixing this for
LoadCurrentDim would no be trivial)
Note that without the fQuickLoad flag set to true, branches
that are used several time in the same formula are loaded
several times. (With fQuickLoad set to true, they are loaded
only once). Solving this inefficiency is a difficult tasks,
since we would need to insure that the branch is read exactly
once not matter what the value of branch->GetReadEntry is.
In addition, this could only take in consideration the formulas
within the same TTreeFormulaManager. And this would have to
be done without any significant loss for the simple case and
for the case where we can do Boolean optimization (i.e. case
where the content of the branch is not needed to know the
final result of the formula).

*****************WARNING*****************
With this mega patch, we introduce support for TTree/TChain with more than
2 billion entries. Several class data members have been changed from
Int_t (or Stat_t) to Long64_t.
==>Trees written with this new version cannot be read with older versions
******************************************
TBranch:
========
- replace the members with type Int_t or Stat_t by Long64_t
Long64_t fEntryNumber; // Current entry number (last one filled in this branch)
Long64_t fReadEntry; //! Current entry number when reading
Long64_t fEntries; // Number of entries
Long64_t fTotBytes; // Total number of bytes in all leaves before compression
Long64_t fZipBytes; // Total number of bytes in all leaves after compression
Long64_t *fBasketEntry; //[fMaxBaskets] Table of first entry in eack basket
- corresponding changes in the member functions
virtual Int_t GetEntry(Long64_t entry=0, Int_t getall = 0);
virtual Int_t GetEntryExport(Long64_t entry, Int_t getall, TClonesArray *list, Int_t n);
