Andrew Werner e2cf734490 aya: Implement RingBuf
This implements the userspace binding for RingBuf.

Instead of streaming the samples as heap buffers, the process_ring
function takes a callback to which we pass the event's byte region,
roughly following [libbpf]'s API design. This avoids a copy and allows
marking the consumer pointer in a timely manner.

[libbpf]: https://github.com/libbpf/libbpf/blob/master/src/ringbuf.c

Additionally, integration tests are added to demonstrate the usage
of the new APIs and to ensure that they work end-to-end.
