Remove
using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.
Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.
Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

- Add new directive 'xpd.datadir' to better control the user data directories and their
permission settings. The syntax is 'xpd.datadir <datadir> <opts>' where <datadir> is
the root path for the datadirs (the final datadir will be <datadir>/<group>/<user>) and
<opts> can contain a combination of the following letters: 'g', 'a', 'M', 'W' ["gW"];
the lower case control the write permissions: 'g' group, 'a' everybody; the upper case
control where the data dirs shoudl be created: 'W' on the workers, 'M' on the master,
"WM" everywhere.
- Better handle the removal of empty data directories in TProofServ and derivatives
- In TProofOutputFile:
- extend support for URL options
- correctly take the URL options into account
This should solve a problem observed in the new ALICE CAF.

From Axel:
Move CINT specific initialization (i.e. preventing CINT from #include-ing files it cannot parse) from TRint into TCint. Consistently tell the interpreter to #include <string>, not <_string>. Set the include path in TCint / TCling so they can load interpreter specific headers (like RtypesCint.h). Whether or not to remove the interpreter includes in TProofServLite::SetupOnFork() will
be studied by Gerri, for now they should not hurt.

From Gerri:
Fix a few pending issues in PROOF-Lite:
- Source the env file before running 'proofserv'; this allows to run valgrind
or other wrapper scripts (e.g. experiment-specific environment initializers)
before proofserv, as in normal PROOF
- Fix a problem with Load()
- Add the possibility for the administrator to control the number of workers
for PROOF-Lite or eventually to forbid the use of it (request on the forum).
The rootrc variable ProofLite.MaxWorkers is read out of /etc/system.rootrc
and cannot be overwritten by users.
Improve handling of Ctrl-C:
- Fix a problem in TMonitor affecting the effectiveness of interrupts.
- Do not send the results from workers to masters if the query has been
aborted.
Miscellanea:
- Make sure that the size of the cache sent back to the packetizer by the
workers is meaningful in case the defaults are used (i.e. not -1).
- Make the current processed element available to selectors via the
input list; this allows to write a more simple and effective packetizers
for tasks where the entry is a file (e.g., dataset generation in the
benchmark suite).

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.
This form allows you to request diffs between any two revisions of this file.
For each of the two "sides" of the diff,
enter a numeric revision.
