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).

local variable "ls" was shadowing method TNamed::ls()? So never us a variable
named ls anywhere in ROOT anymore.

From Gerri:
in TSocket keep track of socket activity using a time stamp. In TMonitor 
use the socket activity timestamp to exclude sockets that have not 
seen activity within a certain time interval.

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 Gerri:
The patch implements the following new functionality:

  - Shutdown of idle sessions when quitting ROOT; if not idle the session
    is shutdown as soon as processing terminates; it is possible to delay
    the automatic shutdown by a tunable amount of time via a new directive
    in the xrootd config file 'xpd.shutdown' (see xpd.cf.example).

  - New static method TProof::Reset(const char *url) to hard-cleanup an
    user area (implemented for Xproofd only); this implied quite some
    additions in XrdProofdProtocol.

  - Possibility to temporary remove / re-insert a worker from the active list
       TProof::DeactivateWorker(const char *ord)
       TProof::ActivateWorker(const char *ord)
    with 'ord' the ordinal numer, e.g. "0.3" .

  - A default url for the disk pool
       const char *TVirtualProof::GetDataPoolUrl()
    It is set by default to a string send back by the master, but it can
    be changed via
       void  TVirtualProof::SetDataPoolUrl(const char *url)

    Jan should then adapt his code to use this as default.

  - Posibility to timeout Collect; for now this is only used at forced
    termination.

The patch includes many small changes and bug fixes. One of the most important
is in TXNetSystem (a bug preventing correct treatment of multiple request
to the same redirector).

From Gerri:
- a new class TXHandler from which TXProofMgr, TXProofServ and TXSlave
  (i.e. all classes owning a TXSocket) derive; this allows to simplify a
  lot the handling of inputs and errors on the asynchronous line.
- a modification to TMonitor to interrupt TMonitor::Select; this is needed
  to avoid being stuck on socket errors which in Collect, and also to treat
  locally Ctrl-C .

Change the TError.h macros:
Assert   ->  R__ASSERT
Check    ->  R__CHECK
Change the TCollection.h macro:
ForEach  ->  R__FOR_EACH
This to avoid potential problems due too trivial macro names.
The old macros will be removed in the next release. Currently
they will print out warning messages with the advice to move
to the new macro names.

From Gerri:
Purpose:
 - Add new Select functionality in TMonitor and TSocket
   This functionality will be used for asyncronous threaded
   reader of TXNetFile.
 - Add support for creation of a TNetFile using an existing
   connection (reuse connection that was already opened by
   TXNetFile while remore side is rootd and not xrootd).

net/inc/TMonitor.h
 - add new private member Bool_t fMainLoop to tell if the
   monitoring has to be on the main loop or outside.
 - add argument 'Bool_t mainloop' to the constructor, default kTRUE
 - add new method SetInterest() to change interest mask of
   a socket
 - add new Select() method for the out-of-main-loop case

net/src/TMonitor.cxx
 - add implemention for the new methods.

net/inc/TNetFile.h
 - add new signature for method Create() to open a TNetFile
   using an existing connection (used to optmize the rootd
   fall back support in TXNetFile).

net/src/TNetFile.cxx
 - add support for new Create()

net/inc/TPSocket.h
 - add new constructor to setup a parallel socket using
   an existing connection (used to optmize the rootd
   fall back support in TXNetFile).
 - add support for new constructor in method Init()

net/src/TPSocket.cxx
 - add implentation of new ctor and related modifications
   in Init().

net/inc/TSocket.h
 - add new method Select() to monitor the socket outside
   the main event loop
 - add new method SetDescriptor() used in TXSocket to save
   the TSocket part
 - add new member fTcpWindowSize and corresponding getter
   for use in the new TPSocket ctor
 - add a 'TSocket *' argument to CreateAuthSocket (default 0)
   to allow re-using of an existing connection

net/src/TSocket.cxx
 - add new method Select() to monitor the socket outside
   the main event loop

From Valeriy:
Lutz from http://root.cern.ch/phpBB2/viewtopic.php?t=1196
suggested to add signal TMonitor class which indicates when socket is ready.
 o TMonitor class is inherited from TObject and TQObject
 o Ready(TSocket * sock) signal is added.
 o TMonitor methods made virtual.
Thanks to Hoinki-Lutz

GetListOfActives() and GetListOfDeActives() now correctly returns a list of
TSockets and not of TSocketHandlers.

can now also use TMonitor to check for write readiness of sockets. Specify
in Add() that the socket needs its write status to be monitored.
