Implementing ConcatFileName and Which to not return a new char[]
to be deleted by the user, but operate on an existing TString.
because of backward compatibility issues I had to introduce new function
names.

   Which(...const char*,...) -> FindFile(...TString&,...)
   ConcatFileName(...const char*,...) -> PrependPath(...TString&,...)

The existing Which and ConcatFilename are now wrappers for the new
TString versions. The wrapping is done in TSystem, so all derived
classes need to implement FindFile and PrependPath now.
I've also fixed a few obvious problems and incompatibilities between the
windows and the unix versions; the VMS version is IMHO still broken. One
of the problems fixed: ConcatFileName(0,"name") returned "name" on unix,
but "\\name" on windows. It now returns "name" for all.

 Attached is the patch to  improve the default speed of TChain::SetProof.

I have added two flags:
  - to control whether the tree header has to be retrieved or not
   (default kFALSE).
  - to force refreshing of the associated fChainProof; default is kFALSE;
    this is used internally by the "Add..." methods if fChainProof is defined,
    so that the new additions to the chain are automatically taken into account
    in the associated data set (this was one of the problems Jan-Fiete had).

TChainProof::StartViewer now checks if the tree header is available and,
if not, tries to get it from PROOF; so the behaviour is always the same,
except that now one waits only when the viewer is started, and not for
normal processing.

This patch adds following issues:
- public dataset management
- separation of directories for different users
- adding TProofServ::HandleDataSets method
- spliting communication in UploadDataSet in two parts (checking name
  and saving)

- I also added these methods:
    virtual Int_t       UploadDataSet(const char *dataset,
                                      TList *files,
                                      const char *dest = 0,
                                      Int_t opt = kAskUser,
                                      TList *skippedFiles = 0) = 0;

    virtual Int_t       CreateDataSet(const char *dataset,
                                      TList *files,
                                      Int_t opt = kAskUser) = 0;

- and added arguments to
    TList      *GetDataSets(const char *dir = 0);
    void        ShowDataSets(const char *dir = 0);
