Very little has changed here since the last submission, namely: using
credentials for security callbacks, and replacing `Arc` with `Ref` (i.e., using
refcount_t to manage ref-counted allocations).

As the message tries to indicate, this is submitted as an example and WIP, it
doesn't have feature parity with the C version yet.
