Add compatibilty with rust-stable.

  * Add feature flag for const-fn functionality, which simplifies some
    things and lets this crate run on architectures where atomic CAS
    isn't available (e.g., thumbv6).

  * Remove `const fn` where necessary to compile under rust-stable.

  * BREAKING CHANGE - Change signature of `Handler::replace` to take a
    mutable borrow. This is required because the underlying type is
    now a NonNull, which needs `mut`. The old behavior was never
    desired, but a consequence of trying to avoid `Option` by using a
    default handler.

  * Use lazy_static crate for initialization of Handler/HandlerArray.

  * Specify Sync for Handler. This is not amazing, since it isn't, but
    it's necessary for initialization in static contexts inside
    `lazy_static`. This should be fine, because any actual
    manipulation of the handler is done in unsafe functions.
