  Patch fixing a problem with log path transmission when the node dies early or not even starts.
  The log path was empty and wrong was filled in when retrieving the log buffers, disorienting
  debugging. This was experienced frequently by ALICE.

  The log file is now trasmitted as part of the responde to the session 'Create' request, so it
  is always registered by the master in the relevant field in TSlave. Also, the last errors, if
  any, typically logged in the xproofd log file, are now copied to the relevant worker or master
  log file so that they are also accessible to client.

  The patch also factorizes some calls in XrdProofdProofServMgr in preparation to the improved
  session lauch strategy.

   - In logs. filter-out by default the service messages used for memory monitoring;
     a new check box has been added to the log dialog box to force display of those
     messages; this reduces considerably the number of 'noise' messages and also the
     default soze of logs.

   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.
