Override a pure virtual function.
Fix for ROOT-6241.
Added a protection when the default c++ library is libc++ (as it is the case for MacOSX 10.9)
Fix problem on Windows with pervious commit
Added more protections to cope when OpenSSL (devel) is not installed in the system.
Fix for very old versions of XROOTD (reported by mikolaj krzewicki)
Better FindXROOTD.cmake to cope with different versions
Add PATH to test-stressproof (CTest)
Fixed streaming issues in TGeoPatternSphPhi and TGeoStateInfo reported by Axel
Apply same fix as http://root.cern.ch/gitweb?p=root.git;a=commitdiff;h=31cf56063d2b5a188888bb6eed244006df4fa87d
for 2D histograms. This fixes ROOT-5900
Added TMCtls.h with thread local storage typedefs for platforms which support TLS
(according to Geant4 tls.hh and G4Threading.hh)
fRenderer, the TMathText Painter, should not be stored.

Fix for https://sft.its.cern.ch/jira/browse/ROOT-5817 (configure checks for freetype-config but then ignores it for #includes)
Reduce the number of Flush (fsync) when closing a TFile.

Rather than doing one call to Flush (fsync) per TDirectory during the execution of TFile::Close
we reduce this to just one call.  Doing so many sync was extremely slow on an ATA disk (order
of 5 minutes for 90000 TDirectories.  With this update the time is down to half a second.
Formatting....
Check for tab container existence, see ROOT-6253.
Fix 2 bugs appearing as a side-effect of the previous fix:

- when cloning fBinHist -call SetDirectory(0) since the TH1(2)Editor manage the histogram
- add the TH1(2)Editor must be registered in the list of cleanups so the contained fHist pointer is set to zero when the referred histogram is deleted
Merge from master the commit 51021491ea9e6dc410cd38fca2a7b0ce6b984ae4

- improve all MinimumBuilder classes :
 - add a print level flag which can be used to control output
 - add a storage level flag which can suppress storing of MinimumState for each iterations
  (useful in problem with large number of parameters >~ 1000) to reduce memory
- add possibility to debug each iteration ny setting anew object MnTraceObject which will be called for every new iteration
- add an example class which histogram function value, edm, and parameters for each iteration
- add in Minuit2Minimizer possibility to enable these new options
Fixes for an error in dictionary generation of TMinuit2TraceObject
Fix for Ubuntu
