From Chris Jones:

Put in place the infrastructure to optimize the I/O writes in the same way we optimized the I/O reads.

Rename TBuffer::ReadSequence to TBuffer::ApplySequence as they can be used both for reading and writing.  The 3 new signatures:

1. virtual Int_t ApplySequence(const TStreamerInfoActions::TActionSequence &sequence, void *object);      
2. virtual Int_t ApplySequenceVecPtr(const TStreamerInfoActions::TActionSequence &sequence, void *start_collection, void *end_collection);      
3. virtual Int_t ApplySequence(const TStreamerInfoActions::TActionSequence &sequence, void *start_collection, void *end_collection);

The 1st version is optimized to read a single object. The 2nd version is optimized to read the content of TClonesArrays and vectors of pointers to objects.
The 3rd version is used to streamed any collections.

In TBranchElement, introduce a set FillLeaves member functions to precalculate many of the (existing) conditional.  Introduction support for the StreamerInfo write actions and sequences.

Replace the ReadLeaves virtual function by a fReadLeaves pointer to member function,
this allows the customization of the ReadLeaves function at run-time depending on the
underlying user class layout in TBranchElement.  This removes many if statements whose
'answer' is known at initialization time.  [ReadLeavesMakeClass and ReadLeavesCollection
still need further decomposition]

Introduce TBranch::Set/GetMakeClass to independently set each branch in MakeClass mode 
and to have a good place to switch the ReadLeaves function appropriately (to and from
the MakeClass mode (also known as the decomposed object mode)).   This can also be
used to reset the mode of some branch with a MakeClass/MakeSelector file.

Properly recover the hierarchy of branch when the top level branch has a trailing dot
and the intermediary branch is TBranchSTL.

Correct the lookup of the CollectionProxy when the sub-branches of a TBranchSTL are
not split (Fixes Savannah #59011).

Expose the sub-branches of a TBranchSTL when calling TTree::Print (by implementing
TBranchSTL::Print()).

From Lukasz Janyst:
   * TBranch: add a possibility of starting from non-zero entry

   * TBranchSTL and TIndArray: new classes for handling STL collections
     of pointers

   * TTree, TBranchElement, TTreeFormula: code handling new type of
     branch added
