Replaces the managed object with the one managed by r.
1) Shares ownership of the object managed by r. If r manages no object, *this manages no object too. The templated overload doesn't participate in the overload resolution if Y* is not implicitly convertible to T*. Equivalent to shared_ptr<T> p(r).swap(*this).
2) Move-assigns a shared_ptr from r. After the assignment, *this contains a copy of the previous state of r, r is empty. The templated overload doesn't participate in the overload resolution if Y* is not implicitly convertible to T*. Equivalent to shared_ptr<T> p(std::move(r)).swap(*this).

4) Transfers the ownership of the object managed by r to *this. The deleter associated to r is stored for future deletion of the managed object. r manages no object after the call. Equivalent to shared_ptr<T> p(std::move(r)).swap(*this).

[edit] Notes
The implementation may meet the requirements without creating a temporary shared_ptr object.
