If the TreeFriend is entered via a TTree*, properly detect that it is in the same file and do _not_ record the filename (since we will alway know where to find it\!)

From Stefan Otto:
If a TChain that has friend TChains is cloned via TTree::CloneTree(), the TFriendElements of the cloned TTrees create unowned files that are not closed by deleting the cloned TChain. Please see attached macro and proposed fix for details.

From Philippe:
TFriendElement is never really the owner of the
TTree is points (in the common case, the TFile objects owns it).
In case where the TTree and its friend are in the same file, this
leads to a double deletion of the friend tree.
The solution is to just remove the deletion of the TTree from
the TFriendElement destructor.
The only downside is that in the case (should be rare!) where
the TFriendElement does not own the TFile and the TFriendElement
is deleted then the TTree will be kept in memory until the file
is deleted.

mega patch to remove almost all compiler warnings on MacOS X where the
compiler is by default in pedantic mode (LHCb also like to use this option).
The following issues have been fixed:
- removal of unused arguments
- comparison between signed and unsigned integers
- not calling of base class copy ctor in copy ctor's
To be done, the TGeo classes where we get still many hundred warnings of
the above nature. List forwarded to Andrei.

This patch prevents core dumps if the file of a tree friend is missing. This can easily happen if a friend is
attached to a tree before it is saved and then in a new session (several days later :)) the tree is reloaded
and analyzed when the original friend is missing.

From Philippe
This patch solves an ownership problem (friend chains on the stack were
delete), it also fix a problem with refreshing the pointer to the leaf
when the leaf was accessed using a tree-alias name. It also enables the
befriending of chains contains series of trees of unequal size (in
parallel).
It also re-enable using string (char*) store into a TClonesArray using a
TTree::Draw command (in the current version it was reading repetitively
the string of the 1st element).

Fixes by Philippe to support Tree friends with TChains.
Still some limitations.The chains have to have a list of file
which have (in parallel) the same number of event. (This is because
(for now) the length of each tree is compared with the other trees).
Also I did not test saving and reloading chains with friend.

New class TFriendElement:
// //
// A TFriendElement TF describes a TTree object TF in a file. //
// When a TFriendElement TF is added to the the list of friends of an //
// existing TTree T, any variable from TF can be referenced in a query //
// to T. //
// //
// To add a TFriendElement to an existing TTree T, do: //
// T.AddFriend("friendTreename","friendTreeFilke"); //
// //
// see TTree::AddFriend for more information //
