This improves readability a lot and prevent us from reinventing the wheel.

Don't compile dynamicoverlay when there is no POSIX shared memory support on the system. Use VLC_UNUSED() iso (void)().

Rewrite old command definitions to no longer use those filthy macros. Added all text functionality so the test application runs successfully.
