 -Mods in TMessage
 When a referenced object or a TRef is streamed to a TMessage buffer,
 the bit corresponding to the uuid of the TProcessID is set in the new data 
 member fBitsPIDs.
 -Mods in TSocket.
  Before sending the TMessage containing a referenced object, the list of
 TProcessIDs is sent through the socket before sending the message.
 The list of TProcessIDs already sent is kept in the new member TList* fUUIds.
 When receiving the message, the TProcessID is stored in the global list of
 TProcessIDs if not already there.

The concrete implementation of the class is in TCint.
The new functions are essentially interfaces to the existing CINT C++ classes
like G__ClassInfo, G__CallFunc, G__DataMemberInfo, G__MethodInfo, G__TypeInfo
and G__TypedefInfo. Most of these functions will call the Reflex interface
once the CINT/Reflex interface will be available later this year.
All direct calls to CINT are replaced by calls like gCint->ClassInfo_xxx where gCint
points to the TCint implementation.
The existing calls to TCint via gInterpreter are kept because on Windows
gInterpreter does not call directly TCint, but instead call TWin32InterpreterProxy
that in turns call TCint.
On Linux and Mac, gInterpreter and gCint are equivalent.

Once the transformation using gCint will be completed, it will be possible
to specify at startup time which version of CINT (CINT or CINT7) by loading
dynamically TCint or TCint7.--This line, and those below, will be ignored--

objects already send through the socket.
In TSocket::Send send an internal message including all TStreamerInfos before
sending the message itself.
In TSocket::Recv read the TStreamerInfo list and update the corresponding classes
in memory, adding a new version if required.

With these changes, a TSocket should be able to support automatic schema evolution.
This is useful when a client and a server use different versions of ROOT, or
different versions of the user classes.

New class providing package management functionality like the AliEn      
Package Management System.                                           
Allows to setup software packages on a local desktop like in the    
GRID environment and to execute the contained programs.              
Registered Dependencies are automatically resolved and missing       
packages are automatically installed.                                
Currently there is no support for 'source' packages.                 
The desired platform has to be specified in the constructor.         
The default constructor takes packages from the global package       
section in AliEn. If you want to install a user package, you have to 
set the AliEn package directory to your local package directory using
     package->SetAliEnMainPackageDir("/alice/cern.ch/user/..../packages")

- Retrieves the file size after it has been closed (anti-mismatch).
- The file was not properly closed in the case of DB troubles. Now the
  file is immediately closed if requested to do so.
- Fix bad troubles when closing files in write mode via TFile downcasting.
- Correctly honor the create/recreate options in Open().

- Allow the size of the (written) file to be retrieved after the Close
  (solves several reported file size mismatches).
