vtkColorString - Helper class for defining a color through a string.

vtkColorString is an helper class for defining a color through one of
the following format:
- #RRGGBB               (6-digit hexadecimal number)
- #RRGGBBAA             (8-digit hexadecimal number)
- rgb(r, g, b)          (where r, g, b are in 0..255)
- rgba(r, g, b, a)      (where r, g, b, a are in 0..255)
- a CSS3 color name     (e.g. "steelblue")

Exclude classes requiring a QApplication from VTK smoke tests

Some classes require QApplication::instance to return true to operate
correctly.  Since TestEmptyInput and TestSetGet do not initialize a
QApplication, exclude such classes from these tests.  Otherwise the
tests crash with Qt5 because QFont expects a QGuiApplication.

Merged vtkColorString into vtkNamedColors.

Removed support for #RRGGBBAA format since is not a valid HTML
color string format. See CSS3 color reference documentation.

Added support for the #RGB short format.
Added support for percentage values in rgb and rgba functional
formats.

vtkTestClorString.cxx source code has been merged into
vtkTestNamedColors.cxx.

Added a new method for get an HTML color string in hexadecimal
format from an instance of vtkColor3ub.

Added a new method for setting a color by name:
void SetColor(const vtkStdString & name,
                     const vtkStdString & htmlString);

No color is set if the name is empty or if `htmlString` is not a valid
HTML color string.

I added a RGBAToHTMLColor and made some minor changes.

Added a vtkStdString RGBAToHTMLColor(const vtkColor4ub & rgba)
method  which given a vtkColor4ub instance as input color returns
a valid HTML color string in the `rgba(r, g, b, a)` format.

FiltersParallelGeometry: move functions to the sources

Avoids unused static function warnings. Plus, now that the tests are all
built into one library, this shouldn't be as much of a problem.

vtkInstantiator: remove instantiator macro from main sources

These functions are fine in the instantiator files themselves and are
not needed in the class files.

vtkCompositePolyDataMapper2: cache opacity check

There is a report[1] that this method takes excessive time in newer
versions. Cache the opacity check based on the input's modified time.

Two comp warnins and a typo in my fix for static/shared build
capability. Also, the triangle.xmf dataset was just wrong.
