Intern: Data race allowed on T

Affected versions of this crate unconditionally implements Sync for Intern<T>. This allows users to create data race on T: !Sync, which may lead to undefined behavior (for example, memory corruption).

The flaw was corrected in commit 2928a87 by adding the trait bound T: Sync in the Sync impl of Intern<T>.
