Introduce support for TTree with variable cluster size (i.e. value of fAutoFlush).
The information is kept in the new data members: fNClusterRange, fMaxClusterRange, fClusterRangeEnd, fClusterSize.
(See TTree::SetAutoFlush for more details).
Iterating through the cluster should be done via the new class TTree::TClusterIterator (i.e. this replaces += fAutoFlush):
TTree::TClusterIterator clusterIter = tree->GetClusterIterator(which_entry_to_start_from);
Long64_t clusterStart;
while( (clusterStart = clusterIter()) < tree->GetEntries()) {
printf("The cluster starts at %lld and ends at %lld\n",clusterStart,clusterIter.GetNextEntry()-1);
}
See TTreeCache::FillBuffer for a concrete usage example.

Allow (via the option kIgnoreMissingTopLevel) for the TTreeCloner to handle the case where the output TTree has more top level branches than the input TTree (this is usefull in case of 'horizontal' merging of TTrees and/or the case of copy and add.)

Fix the default sorting order of baskets when the TTree is an older in-memory TTree.
Enhance the sort order to use the 'entry number' when the seek position are equal.
Consequently the default sort order for an older in-memory TTree is now
essentially kSortBasketsByEntry rather than kSortBasketsByBranch (old 'correct' sort
order) or 'random' (the 'broken' sort order prior to this patch).

Insure the error message string is created before being used.
Reject the case where the input tree is missing a branch compared to the output tree.
In that case, the TTreeCloner can not 'guess' what data to back fill into the missing branch.

TTree::CloneTree and TChain::Merge in fast mode now can recover from some mismatch errors between
the input and output TTrees by falling back to using the 'slow' mode. In particular this allow
a 'fast cloning' to handle files that requires schema evolution (albeit it is of course much slower).
The TTreeCloner constructor takes an additional argument to indicate whether the TTreeCloner should
directly print the mismatch error/warning or if the caller we handle them. The message of the
warning can be retriever via TTreeCloner::GetWarning. TTreeCloner::NeedConversion return true
if there is a mismatch but the TTree will/should be able to be process properly in slow mode.
This fixes the issue #33743 in savannah

From Lorenzo:
this patch fixes some not-consistent usage of TMath::Sort. If it is not
applied, the compilation will fail when I will change
Tmath::Sort<Element,Index> (Long64 n, Element x, Index w)
in
Tmath::Sort<Element,Index> (Index n, Element x, Index w)
to avoid some possible conversion errors from Long64 to Index

From Maarten:
Add a new sort option 'SortBasketsByEntry' to the fast TTree cloning.
With this option the branches' baskets will be reordered so that they
are in the order they will be read when processing the full tree.
