Diff to previous 25918

   First version of the final patch enabling multi-workers on single node using
   PROOF-Lite. This is supposed to improved scalability for large number of workers
   (>300-400) and is currently available only for non-data driven tasks.
   The new setup configuration is enabled by the directive 'xpd.remoteplite 1' in
   the xproofd configuration file.

   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.
