OutputterPrintHeaderFunction is declared as a function of 1 parameter
but CompilerOutputter_printHeader was defined as taking 2.
It is a mystery why this code compiled before.
The logic of `stdimpl_strcmp()` was needlessly complicated and not
understood by scan-build. This change fixes the warning and makes the
code more readable.
Found via scan-build.
The outputter is called ColorTextOutputter and can be enabled by defining OUTPUT=COLORTEXT.
The colored outputter behaves just like the TextOutputter, but displays successful tests in GREEN and failed tests in RED. The summary message is also in GREEN/RED, but is slightly different from the TextOutputter.
Also:
* Added fancy simple none-verbose color-outputter for EmbUnit. The outputter outputs a simple statistics line in GREEN or RED, according to the test success or failure. (Also, the ColorTextOutputter was adjusted to use the statistics output of this new ColorOutputter.) The new outputter can be activated with OUTPUT=COLOR.
* Added a single character "." output for the simple color outputter and replaced the color codes by macros.
