From Fabrizio and me:
- add support for native recursive mutexes (pthread and Win32) and remove
not satisfactory generic recursive implementation.
- remove support for older pthread versions (PthreadDraftVersion < 10),
all modern systems support version 10 now.

From Federico Carminati:
"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."

From Constantin Loizides
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.

From Maarten and me:
Changelog:
- Fixed a problem with TSemaphore where the owner of the lock in
the associated TMutex was not properly updated by the low level
pthread_cond_wait relock. (always remember our TMutex in TCondition)
- Unify thread ID's as Long_t
- Simplify and regularize TThread::Join(). Join with a thread based on
tid or TThread *, hide implementation more cleanly, remove unnecessary
member functions and variables (fJoinId et al)
- Make TThread::Ps() static (easier from cmd line)
- Use -1 iso 0 for unknown thread id as 0 is a valid value
- add more error checking in lots of places
- move gContainerMutex and gCINTMutex initialisation with the rest of
the one time init bunch.
- Simpify Exists()
- Lock *all* access to the global thread list

From Mathieu de Naurois <denauroi@in2p3.fr>
"From the manual of pthread_cond_timedwait, I have:
pthread_cond_timedwait atomically unlocks mutex and waits on
cond, as pthread_cond_wait does, but it also bounds the duration
of the wait. If cond has not been signaled within the amount
of time specified by abstime, the mutex mutex is re-acquired
and pthread_cond_timedwait returns the error ETIMEDOUT.
The abstime parameter specifies an absolute time, with the same
origin as time(2) and gettimeofday(2): an abstime of 0
corresponds to 00:00:00 GMT, January 1, 1970.
In the code of ROOT, the line:
while (fgXAct) {fgXActCondi->TimedWait(1);}
was a nonsense that it equivalent to :
while(fgXAct);
and it uses 100% of CPU.
I modified the TThread class in the version we use for HESS.
For us, in a heavily multithreaded DAQ, this modified version works fine
and is faster when opening canvases from threads."

introduce new abstract class TVirtualMutex in base and move TLockGuard from
thread to base. TMutex now derives from TVirtualMutex. Also add zero
overhead macros to be used to place mutexes (zero overhead in case ROOT
is not compiled with thread support). Added, example, global container
mutex which should be initialized when libThread is loaded to point to
a real mutex. To be done and tested by Mathieu de Naurois.
