Subject: [PATCH v2 0/2] Arc methods for linked list

This patchset contains two useful methods for the Arc type. They will be
used in my Rust linked list implementation, which Rust Binder uses. See
the Rust Binder RFC [1] for more information. Both these commits and
the linked list that uses them are present in the branch referenced by
the RFC.

I will send the linked list to the mailing list soon.

This patchset is based on rust-next and depends on [2].
