This implements more of the dlfcn functionality. Most notably: * It's now possible to dlopen() libraries which were already loaded at program startup time. This does not cause those libraries to be loaded twice. * Errors are reported via dlerror() rather than by crashing the program. * Calls to the dl*() functions are thread-safe.
