Add a linked-pair abstraction to bufferevents. The new bufferevent_pair abstraction works like a set of buferevent_sockets connected by a socketpair, except that it doesn't require a socketpair, and therefore doesn't need to get the kernel involved. It's also a good way to make sure that deferred callbacks work. It's a good use case for deferred callbacks: before I implemented them, the recursive relationship between the evbuffer callback and the read callback would make the unit tests overflow the stack. svn:r1152
