"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

to 0. Create a global static TGlobalMutexGuard object which will cause
the TGlobalMutexGuard dtor to be called when libThread is unloaded (at the
end of a ROOT program). This fixes problems with ROOT crashing at exit
because gGlobalMutex was not 0 and still accessed while the Thread library
was already unloaded.

Dictionary G__%.o: G__%.cxx rules now in main Makefile instead of Module.mk's
=> changes in Module.mk.

First Module.mk's included, then Makefile.precomp - we need ALLHDRS defined

Split $(PCHEXTRAOBJ) and $(PCHFILE) rules - fixes clash with make -j2

Define CINTCXXFLAGS:= - otherwise they will contain PCHCXXFLAGS via
their definition as a copy of CXXFLAGS.

some small mods that prepare the ground for the new PROOF patch:
- TMessage.h, TMonitor.h: add friendship to new socket classes
- TSemaphose: support relative timeout in Wait()
- TUrl: in GetUrl() add option to also get default port numbers as part
        of the url.

in case we have gmake >= 3.80 we can use the new | (order) syntax where
all dependencies after the | are required to be there but not trigger
execution of the rule. This should greatly enhance the build experience
on Win32 and AIX (platforms that need the EXPLICITLINK option).

This patch implements:
- decentralized, automatic mutex initialization,
  see R__LOCKGUARD2 in TVirtualMutex
- PROOF parallel startup fixes
- more thread protection (in base, cont, meta, rest to be done)
- cleanups

From Eddy Offermann:
TString::Atoi and Atof are made const.

Patch introducing parallel startup of the slave servers. This new feature
will considerably reduce the startup time in PROOF setups with many 10's
to 100's of slaves. By default this feature is off, turn it on in the
[system].rootrc file by uncommenting the line:

Proof.ParallelStartup: yes

Summary of changes:

Index: Makefile

  - Add the thread lib to PROOFLIBS

Index: base/inc/TVirtualMutex.h, base/src/TVirtualMutex.cxx

  - Protect static buffer in DebugPrint with specific global mutex

Index: config/Makefile.depend

  - Add dependence on thread lib for PROOF

Index: config/rootrc.in

  - Add description of new envs
      Proof.ParallelStartup, Auth.Timeout, ProofServ.UseSSH

Index: net/inc/TAuthenticate.h

  - Add new member fTimeout to indicate timeout situations
    and new method HasTimedOut() to retrieve it.
  - Add new static member with the timeout value in sec
    and method SetTimeOut() to set it
  - Add new method CatchTimeOut() called at timeout expiration


Index: net/inc/THostAuth.h , net/src/THostAuth.cxx

    protocol that has timed-out

    lost in a previous patch)
  - Disable by default SSH for PROOF servers
  - fix a couple of small memory leaks

Index: net/src/TPSocket.cxx

  - Fix logic in Close() (if called too early (e.g. timeout)
    the underlying socket can still be open and needs to be
    closed).


Index: net/src/TSocket.cxx

  - initialize member fTcpWindowSize in all constructors
  - modify error logging after an unsuccessful authentication
    attempt, checking for timeouts.
  - disable SSH for PROOF servers

      SubmasterStartupThread(void *) executed in threads
    - add Bool_t argument to all implementations of StartSlaves

Index: proof/src/TProof.cxx

    - add internal classes ProofThread and ProofThreadArg to keep
      track of started threads and to pass arguments to threads
  - cleanup fPlayer and fFeedBack in destructor

- remove dependence on direct G__xxx CINT code, since CINT is not
  reentrant there is no change we can currently run interprered function
  as thread functions. This avoids also usage of the CINT lock in
  the thread code which could lead to deadlocks when threads were
  created in a constructor of an object created via the plugin manager
  (which uses CINT to execute the ctor).

- added thread safe versions for the DoError() and ErrorHandler() functions
  which allows TThread::Info() and family to be called from threads.
  Idem for the Printf() function.

- by Maarten, added a join helper thread that will avoid the main thread
  from blocking while doing a join and thereby not being able to process
  events or handle messages sent from the threads via the XARequest
  method.

- fix several memory leaks (valgrind).
