Comment(by asn):

 wrt the bufferevents case, it seems like connection_or_handle_event_cb()
 handles renegotiation appropriately and no changes need to be made. It
 also uses tor_tls_read() and tor_tls_write() normally, so excess renegs.
 are blocked.

 If I had to make a change in connection_or_handle_event_cb() I would add a
 `tor_assert(tls->got_renegotiate)` in the body of:

 {{{if (handshakes == 2) {}}}

 But it's probably needlessly aggressive and I don't feel I know
 connection_or_handle_event_cb() well enough.

 I tested the both cases (bufferevents and no-bufferevents) in a privnet.
 they seem to work.
