This patch eliminates TVirtualProof, TVirtualProofMgr and TVirtualProofDesc.
The first is integrated in TProof, the second in TProofMgr and the third
becomes TProofDesc defined in TProofMgr.h.

new class TObjectSpy and TObjectRefSpy. These small classes monitor objects
for deletion via RecursiveRemvoe() and reflect the deletion by reverting
the internal pointer to zero. When this pointer is zero (via GetObject())
we know the object has been deleted. This avoids the unsafe
TestBit(kNotDeleted) hack. The spied object must have the kMustCleanup bit
set otherwise you will get an error. To be used in editor management.

  sessions
- use xrootd/xproofd as connection daemon

This patch contains two new very small utility classes:

  1. base/inc/TRedirectOutputGuard.h

     Very simple guard class for RedirectOutput (similar to TLockGuard)
     to redirect the output to a file. Usage:

     void redir() {
        TRedirectOutputGuard guard("/tmp/pippo.txt","w");
        Printf("Here we go ...");
        cout << "Me too!" << endl;
     }

     If the file does not exist it is created. The mode has the same meaning
     as in TSystem::RedirectOutput(). When the guard object goes out of scope
     the redirection is restored to stdout and stderr, this is exception
     safe.

  2. gui/inc/TGRedirectOutputGuard.h, gui/src/TGRedirectOutputGuard.cxx

     Same functionality but with a text frame window. Usage:

     #include "TGTextView.h"

     void guiredir(TGTextView *tv, const char *fout, const char *mode) {
        TGRedirectOutputGuard guard(tv, fout, mode);
        Printf("Here we go ...");
        cout << "Me too!" << endl;
     }

     where 'tv' is a TGTextView object initialized by the caller; optionally
     one can save the logs into a file.

here are my modifications to interface the Grid file catalog
(AliEn in this case) with TChain data sets. Some changes are just
one-liner changes to make some base class things virtual or to set
some members. With these changes one can do:

// connect
TGrid::Connect("alien://");

// query
TGridResult* result = gGrid->Query("/alice/cern.ch/user/p/peters/analysis/miniesd/","*.root","","");

or

TGridResult* result = gGrid->Query("/alice/cern.ch/user/p/peters/analysis/miniesd/","*.root","","-l 50");  // to query maximum 50 files

result->Print(""); // or result->Print("l") or result->Print("all"); => Tells you also the complete size of the TDSet (the ALICE one is 68 GB)

// build chain for ALICE files
TChain* mychain = new TChain("esdTree","AliceSession");

// Get a list of FileInfo Objects
// -> I cannot use directly a list of FileInfo objects in TGridResult,
//    because TGridResult can be also a list of jobs etc ....

TList* list = result->GetFileInfoList()

// add them to a chain
mychain->AddFileInfoList(list);    // adds all
mychain->AddFileInfoList(list,10); // adds only the first 10

// to use PROOF then, you need to do
mychain->Lookup();                 // open's all files via TAlienFile over
                                      the redirector and replaces the
                                      alien URL with the physical location
                                      of the file on the cluster
                                      (including the access token)

mychain->SetProof();
mychain->Draw("ESD.fTrigger");

Big patch restructuring the authentication code so libCore does not depend
on libssl etc. anymore. Isolate the current authentication code behind a
plugin library to be loaded on demand.
Setup of a framework able to manage both sets of authentication modules
(the current one and the one based on xrdsec, coming soon).
Cleanup all direct reference to authentication in TSlave and TProofServ,
allowing for significant simplification for the forthcoming changes
in PROOF for XPD.

New module: auth

New files: base/inc/TVirtualAuth.h
           auth/Module.Mk
           auth/inc/LinkDefRoot.h
           auth/inc/TRootAuth.h auth/inc/TRootSecContext.h
           auth/src/TRootAuth.cxx auth/src/TRootSecContext.cxx

Moved files:
   net/inc -> auth/inc : TAuthenticate.h THostAuth.h DaemonUtils.h AuthConst.h
   net/src -> auth/src : TAuthenticate.cxx THostAuth.cxx DaemonUtils.cxx

which uses the plugin manager to load a concrete archive reader. Currently
the TZIPFile class provides a ZIP archive reader. One can also imagine a
TTARFile to read tar files. We advice however to use ZIP archives since they
allow direct access to all its members via a directory structure which
is part of the file. The archive file access has been integrated into TFile
which also functions as byte reader to access the archive. This has the
enormous benefit that archives can be accessed using all the existing
remote file access classes, like TNetFile, TRFIOFile, TCastorFile, etc.

When creating ZIP files containing ROOT files make sure that the ROOT files
are not compressed since normally they are already ZIP compressed. on Linux
one can create a ZIP archive doing:

    zip -n root multi file1.root file2.root file3.root ...

which creates the archive multi.zip, with all files ending with .root
not compressed.

The ROOT files in an archive can be simply accessed like this:

    TFile *f = TFile::Open("multi.zip#file2.root")
or
    TFile *f = TFile::Open("root://pcsalo/multi.zip#2")

where the second form opens the 3rd ROOT file in the archive via rootd.

A TFile can also be used to just browse an archive file, like:

     TFile *f = TFile::Open("multi.zip")
     f->GetArchive->Print()

A TBrowser interface will follow shortly.

The core ZIP reading code has been kindly provided by Lassi Tuura.

PROOF and file I/O performance monitoring framework. The TVirtualPerfStats
abstract class allows adding monitoring events in base classes (TFile and
TNetfile). The performance monitoring info allows detailed study of PROOF
performance (which files accessed by which slaves, latency, read/write times,
packet size, etc.). The result is send back to the client in the form of a
memory based TTree.

Remove TProofStats.h and TProofStats.cxx, .d, .o from proof/inc and src.

base/inc/LinkDef3.h, mp.h, multmp.h move the creation of pairs from cintdlls to libCore to force the creation of the
I/O.  This is necessary to allow the std::pair I/O when the cintdll are created.

TEmulatedVectorProxy: fix a memory leak
TClass: set a uninitialized value in constructor.  Also remove trailing spaces.
base/Module.mk: remove warnings from G__Base3.cxx for icc.

of TObjNum<void*> (for backward compatability we provide the typedef:
typedef TObjNum<void*> TObjPtr;). Remove reference to TObjPtr.h from
TBuffer.cxx. To compile make sure to remove base/src/G__Base1.d,
base/src/G__Base2.d, base/src/G__Base3.d and base/src/TBuffer.d.

(since containing a TObject in addition to the basic type) it is useful in
some circumstances, like TObjString.

overhead macros to be used to place mutexes (zero overhead in case ROOT

a real mutex. To be done and tested by Mathieu de Naurois.
