UTF8: Fl_Text_Display and related:

+ Made char * text() const., this method should be further checked for UTF8 compat.
  + Added a fixme comment to remember we must check for the potential incorrect
  assumption that that a buffer size equals the string length + 1.
  + Correct a protected attrib. typo as we  don't need to care about ABI compat. for now.
