* Remove ROOT.ROOT calls in the Python tutorials except for
  EnableImplicitMT to keep backwards compatibility until 6.24
* Use rdfentry_ instead of tdfentry_
* Use df for variables instead of tdf

[ROOT-10551] Plotting with disjoint ranges can be tricky, since the
normalisation of the PDF depends on its plotting range. The new tutorial
rf212 shows how to use NormRange to obtain identical normalisations.

* Remove empty lines
* Remove unnecessary braces in expressions
* Add missing | for df105

Add plotting of result histograms in TMVACrossValidationApplication tutorial

Use proper method to set auto color

* IsDataContainer does not recognize anymore a std::string as conainer
* TypeTrait is move to RDF/Utils.hxx in the namespace
  ROOT::Internal::RDF

Return "bird" when no palette name specified
Adjust draw_rh2_colz.cxx example

Complete class renaming

Histogram drawable does not need to have reference - it uses palette
drawn in the frame

They have different attributes
Moreover, 2D histogram may be drawn with RPalette

Some RDrawable may require RFrame, therefore when such drawable add to
the pad, automatically RFrame will be created

Doing in two steps to keep git rename history clear

It is bound to RFrame coordinates and only margin and height can be
specified
