Track open buffers when handling sync requests

Browse source 
When a host sends a buffer to a guest for the first time, they record that
they have done so in a set tied to that guest's peer id. When the guest
reconnects and syncs buffers, they do so under a different peer id, so we
need to be sure we track which buffers we have sent them to avoid sending
them the same buffer twice, which violates the guest's assumptions.
