s3: Wrap calls to the s3 registry API.
To use Samba 4's libregistry in the registry editor, some compatibility issues with Samba 3 need to be addressed. "struct registry_key" is defined differently in source3 and source4, and so this wrapper is used to isolate conflicting types and avoid headaches compiling the code.
