   First version of PROOFLite, a 2-tier realization of PROOF intended for multi-core
   machines. In PROOFLite the client start directly the workers; no daemon is required.

   Currently this works on Unix only. Some issues with the internal connection still need
   to be sorted out on Windows.

   To start a session just use

            TProof::Open("")  or TProof::Open("lite")

   From there on everything should be as in normal PROOF. To start a standard PROOF
   session (i.e. via daemons) on the localhost use TProof::Open("localhost").
   (The default meaning of "" in TProof::Open() is controlled via the rc value
    'Proof.LocalDefault').

   To run stressProof with PROOFLite pas the argument 'lite':

            ./stressProof lite

   By default, PROOFLite sets the number of workers equal to the number of cores.
   The number of workers is controlled by the rc variable 'ProofLite.Workers'; it can
   also be set on the fly with the option "workers=<n>", e.g. TProof::Open("lite?workers=2").

   This patch also introduces the rc variable 'Proof.Sandbox' to control the local location
   of the sandboxes. The default has been changed from "~/proof" to "~/.proof" to avoid
   interferences with possible users' working areas. The sandbox contains the directory
   'packages' (with the clients packages; used by standard PROOF and PROOF Lite),
   and some directories used only by PROOFLite: 'cache' (binary cache) and 'datasets' with 
   the datasets. The location of these directories is controlled by the rc variables
   'Proof.PackageDir', 'Proof.CacheDir' and 'Proof.DataSetDir'.
   The working directory for PROOFLite is in the form workdir=<sandbox>/path-to-current-dir where
   ~/path/to/current/dir is the directory from where the session in launched. The directory
   <workdir> contains the session working dirs (in the form 'session-<host>-<time>-<pid>'),
   with the symlink 'last-lite-session' pointing to the last started session, and the 'queries'
   directory, with the results of queries started from the current directory.

Set property svn:eol-style LF on all source and Makefiles. This should avoid
problems with Win32 line endings ending up in the repository. All MS tools
support LF eols fine.

From Anna:
- Add support for entry-lists to PROOF.
From me:
- Cleanup usage of TEntryList/TEventList arguments in the TProof/TProofPlayer API.

From Gerri:
This is the patch to move TDSet and TChainProof in 'proof' and remove
any dependence on PROOF in 'tree'. I have renamed TChainProof as TProofChain,
for consistency. TProofChain is now deriving from TChain and overrides only
the required methods. It is loaded via PluginManager by TChain in SetProof.
TQueryResult stores now all the input-related objects in fInputList. There
is a new method
   TObject *TQueryResult::GetInputObject(const char *classname)
to retrieve the first  instance of a class from the input list, so for the
TDSet:
   TQueryResult *qr;
   TDSet *dset = (TDSet *) qr->GetInputObject("TDSet")
The changes in TSessionViewer are needed to adapt to this new way of
accessing TDSets.

From Gerri:
Fixes several issues with the definition of the outputlists which were forgotten
 during the previous patch against memory leaks. And also a few other things.

From Gerri:
Big patch supporting query queueing on the PROOF master, interogation and
interaction with the queue. Retrieval, finalization and archival of query
results and multiple PROOF sessions. Some other fixes:
- TMacro.h, .cxx
  add method Checksum to get the MD5 of the current context
  (needed for optimized selector reinitialization)

- Changes needed to create and fill the list of data sets (TROOT,
  TDSet, TChain, TChainProof)

- A new method TSelector::IsStandardDraw() to check if a selector
  is for standard draw actions

- TEventIter: fix for the missing last update (see above)

- Few protections in TPacketizers destructors

- Fix for code conventions in TPerfStats (the other will follow)

- Occasional missing last update of the progress bar (systematically
  reproduced with SetParallel(1)): all this part is quite involved
  and I have found a solution which does not harm but perhaps is not
  the most elegant.

- SetParallel(0): the progress bar was not working at all in such a
  case, since no packetizer is involved. Still it is useful to see
  that things are not stuck, so I have added some progress messages
  there too. The problem is that I have not found a way to get the total
  number of entries from a data set without doing all the machinery
  done in the packetizer.
