Title: DLL loading

This mimics the DLL loading procedure in `loadNamespace`. It registers DLLs and can load functions from DLLs, with this sort of directive in NAMESPACE:

```
useDynLib(mypkg,myfunction)
```

I also renamed the `dll-unload` test package to `dll-load`, because it seems more appropriate now.
