When looking at how dlopen for various libs is implemented, I found that the macros hide too much. I find it much easier to see what is going on if 'extern' and '= NULL' are written explicitly. After all, we don't hide those for other definitions, e.g. our style guide says that static variables should be initialized with '= NULL'. With that change, it's much more obvious what is a variable declaration and what is a variable initialization.
