From ideas provided by Mike Marino, introduce TClonesArray::ConstructedAt which
always returns an already constructed object. If the slot is being used for the
first time, it calls the default constructor otherwise it returns the object as
is (unless a string is passed as the 2nd argument to the function in which case,
it also calls Clear(second_argument) on the object).
This allows replace code like:
for (int i = 0; i < ev->Ntracks; i++) {
new(a[i]) TTrack(x,y,z,...);
...
...
}
...
a.Delete(); // or a.Clear("C")
with the simpler and more efficient:
for (int i = 0; i < ev->Ntracks; i++) {
TTrack *track = (TTrack*)a.ConstructedAt(i);
track->Set(x,y,z,....);
...
...
}
...
a.Clear();
even in case where the TTrack class allocates memory.

From Tobias and Mohammad:
added a new AbsorbObjects() which absorbs a range from one clones array
to another and re-indexes the old one.

From Jason Detwiler:
I put together several functions useful for me in the context of event building.
I have an event structure containing several TClonesArrays, and during event
building I have the need to merge events and sort their data. So I developed the
following two functions to deal with the events' TClonesArrays during those
procedures:
void TClonesArray::AbsorbObjects(TClonesArray* tc)
//Directly move the object pointers from tc to "this" without cloning (copying).
// "this" takes over ownership of all of tc's object pointers. tc is left empty
//upon return. I preferred this to copying / cloning from one TClonesArray to
//the other in order to save the copying time.
void TClonesArray::MultiSort(Int_t nTCs, TClonesArray** tcs, Int_t upto = kMaxInt)
// Sort multiple TClonesArrays simultaneously with "this".
These new functions make use of a new function in TSeqCollection:
void TClonesArray::QSort(TObject *a, Int_t nBs, TObject **b, Int_t first, Int_t last)
//Utility function for MultiSort

Add new member functions
void SetClass(const char *classname,Int_t size=1000);
void SetClass(const TClass *cl,Int_t size=1000);
Set class is now called from the two TClonesArray constructors.
The new functions are useful when a TClonesArray is a member of another class and the decision
about the class to be put in the array can only be taken
after the construction of the parent class.

Instead of providing default implementations for copy ctor's and assignment
operators we better make them private (and not implemented) to avoid people
from accidentally using them. Especially the collections classes and the
TQObject derived classes. In these classes the default implementations would
cause havoc due to multiple deletions of the same objects and other
potential memory corruptions.

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."

SetOwner is now a virtual function so that it can be customized.
A TClonesArray is always the owner of its content but it's base
class (TObjArray) is never the direct owner. Hence we need to
disable SetOwner for TClonesArray.

New functions TClonesArray::BypassStreamer and TClonesArray::CanBypassStreamer.
By default, the kBypassStreamer bit is set in the TClonesArray constructor.
When this bit is set, TClonesArray::Streamer does not call the class Streamer function,
but use a more efficient code.
Addition in function Streamer to call ForceWriteInfo for the class referenced by
the TClonesArray. This change was necessary to read empty TClonesArray.

introduced the concept of ownership for all collections. By calling
TCollection::SetOwner() a collection becomes the owner of its elements.
In those cases the dtor and Clear() method will delete the items and not
just free the container space. Also all collections now make their
TObject part persistent (so the TObject bits are saved). Version numbers
were properly increased.
