Data race in v9

Affected versions of this crate unconditionally implement Sync for SyncRef. This definition allows data races if &T is accessible through &SyncRef.

SyncRef derives Clone and Debug, and the default implementations of those traits access &T by invoking T::clone() & T::fmt(). It is possible to create data races & undefined behavior by concurrently invoking SyncRef::clone() or SyncRef::fmt() from multiple threads with T: !Sync.
