We have virInitialize() as an explicitly callable function in libvirt.so
because it was needed for thread safety before we introduced proper
thread support.

Now that we're using virOnce to do atomic initialization, AFAIK, there is
no compelling reason for a virInitialize function to be called explicitly.

So I'm not convinced we need to expose virAdmInitialize, unless I'm
forgetting something
