List selected classes at default verbosity

as genreflex for ROOT5 did.
Useful for example for debugging reasons in presence of logfiles.
Fix Streamer when the UserInfo contained TRef-ed objects.

When TTree::fUserInfo contains (directly or indirectly) an
object that is referenced by a TRef and (one of) the TTree
being processed has the BranchRef enabled, the TObject
Streamer will incorrectly.

See also ROOT-5922.
Remove any mention of ROOT_Math_VectorUtil_Cint
Handle URL's like: http://host?opt=1. Fixes ROOT-5915.

Also add new method HasOption(const char *key) which returns true if the
specified key appears in the URL option lists. In the above URL
HasOption("opt") returns true.
remove commented out code.
comment out new code that depends on server side includes. Needs fixing.
The standard forbids signedness specification on wchar_t (ROOT-5921).
Simplify access to Normalized name

now it's only necessary to have the decl and the interpreter.
Use simplified GetNormalizedName interface
Correct name of warning emitter
Adjust routines following ROOT-5906

now the template parameters are not reconstructed using the source
manager (and therefore vulnerable to, for example, preprocessor
statements) but the template parameters accessed through the clang
API.
In presence of a non strongly typed enum as template parameter
the forward declaration is bailed out since it is not possible
to have one. The transition to c++11 and strongly typed enums
will allow the forward declaration of those.

Protect in case of only 1 point. Fix ROOT-5397
Fix a bug (ROOT-5200) in computing the bin errors in TH2::Smooth
Apply fixes for ROOT-5058

Add SetBins method in TEfficiency
Add new methods CreateGraph and CreateHistogram which create the histograms used to paint the class. They can now be called without drawing it.
Fix a couple of tutorials.
Merge branch 'master' of https://root.cern.ch/git/root
Update cocoa tutorials to make it possible run them all in one session (before

they were using the same color indices for custom colors and this was not good at all).
Also, make these tutorials look more ... modern (?) and reasonable, add some primitive error handling at least.
FindFreeCustomColorIndex - scan gROOT's color indices and search the first free (in some hardcoded range).
Remove forgotten printout
