Chirantan Ekbote f1444aaf72 data_model: Implement Send + Sync for IoSliceMut ... Pointers in rust don't implement Send or Sync and so any struct that contains a raw pointer doesn't implement those traits either. However, there's nothing inherently unsafe about sending a pointer across thread boundaries. The only unsafety comes from actually de-referencing the pointer, which already requires an unsafe block. Explicitly implement Send + Sync for IoSliceMut since the iovec internally holds a *mut c_void, which prevents those traits from being auto-implemented. Send + Sync is also implemented by std::io::IoSliceMut, which is almost exactly the same as our IoSliceMut, so that can provide some additional reassurance that this is safe. Also add a missing copyright header in the file.
