Following Igor Smirnov analysis fix several memory leaks, add checks for null pointer dereference, fix or add copy constructor and assignment operator when applicable, make the copy constructor and assignment operator private when the objects are not intended to be copiable.

-Remove the static functions: ReadProcessID and WriteProcessID.
These two functions have been moved to TVirtualIO and TFileIO.
-Implement new functions;
void CheckInit()
static TProcessID *GetPID();
static TObjArray *GetPIDs();
With these changes TProcessID is now independent of the I/O sub-system.

From Axel:
---
Add support for auto-loading of TRefs from multiple TProcessIDs:
TRefTable now stores 2d arrays of branch numbers to load [PID][UID] (via
FillBuffer). The PID index <-> TProcessID-GUID mapping is stored via
TRefTable::Streamer (i.e. once per TTree). Lookup is cached. This change
is both backward and forward compatible, both concerning the interface
and .root files. Only exception is TRefTable::fParentIDs, which is now
only streamed via FillBuffer / ReadBuffer, not as a member of TRefTable.
Minor side-notes:
* Speed-up in TRef::GetObject de-referencing (only once call to
TProcessID::GetObjectWithID).
* No re-reading of a branch if it was already read for an event (if
TBranchRef's fReadEntry == branch-to-autoload's fReadEntry then don't
call GetEntry on it).
* Added getter for TProcessID::fgPIDs->Size()
* updated doc for TRef, TRefTable, TBranchRef, to reflect the current
status of auto-loading.
---
The only change that's breaking backward compatibility (as mentioned
above) is the clear split between per-entry and global streaming of the
TRefTable: there is no use in storing the fParentIDs[][] array (and
fN[]) as part of the TTree members - it should only be stored as part of
the TTree entry. So I've marked them as //!; they're made persistent in
TRefTable::FillBuffer.
The member TRefTable::fSize is only around to suppress a warning in the
schema evolution algorithm (it was a counter before, and the schema
evolution algo is unhappy about fSize missing in the new class
definition, nor does it appreciate fSize being marked as //!). This is
ugly, but I prefer it over a custom streamer.
The patch should fix the following issues:
* autoloading doesn't work because TRefs were created by different
processes,
* changed objects magically overwritten in memory due to re-loading of
referenced objects

From Philippe:
This patch solved a problem due to the fact that TObject's fUniqueID can
only hold a 8 bits ProccessID identifier (in addition to storing a 24 bits
object ID). However we support 65535 distinct ProcsssID identifiers per
file. Before this patch, for a file containing more than 255 distcint
ProcessID, the
TRef using the later ProcessID would be unable to find their references.
Specifically, fUniqueID can now store the ProcessID indentifier 0 through
254. When more identifiers
are used, then instead of store the identifier in the 8 higher bit of
fUniqueID we store in a table (TProcessID::fgObjPIDs) linking addresses to
pids.

Several changes in the handling of TRef to support the following use case:
An array of objects is written to a file but the TRefs
referencing these objects are not written to the file.
In a next session, these objects are read in memory
and new TRefs point to these objects and are written
to a separate file. In a third session both files
are connected.
To get this scenario working, one must use a dummy TRef
set to all objects that can be referenced in the next session.

Add new static function GetSessionProcessID return the current
session TProcessID.
Rewrite the function ReadProcessID in order to store the right pid
in the list of the files pids in case the pid is already existing
in other files.

Many functions previously in TRef moved to TProcessID.
The first time a referenced or referencing object is written to a file,
the corresponding TProcessID is also written.
The ObjectCounter fgNumber also moved to TProcessID.

Backward incompatible change of TProcessID. The new version supports
the new versions of TRef and TRefArray.
Instead of using a TExMap to store the pointers to the referenced objects,
a simple and faster TObjArray is created. Each array element points directly
to the referenced object. The array index corresponds to the fUniqueID
of the referenced object.
