completely changed the VData/VDataEnum system: Multiple VData can share one VDataEnum via an Arc<Mutex<VDataEnum>>. If one wants to modify the data, it copies it (Copy on Write). This copying is skipped for shared mutable data (references). This was necessary for the get_ref() function. Expect bugs!

// because we handle all callbacks, this never returns Err(unhandeled message).
// it returns Ok(()) if mers exits (i/o error in stdin/stdout), so we also exit if that happens.
