maint: Fix doxygen build system integration

* doc/module.mk (doxyhtml): Add Doxyfile as a prerequisite.
(doxyhtml-maintainer-clean): Simplify rule to clean doxyhtml directory.

* Doxyfile.in (PROJECT_LOGO): Use correct path to icon.
(STRIP_FROM_PATH, INCLUDE_PATH, INPUT, EXAMPLE_PATH): Use abs_top_srcdir.
(PREDEFINED): Add HAVE_OPENGL and HAVE_QSCINTILLA to the list, sort.
