Comment(by nickm):

 So, this is tested to prevent multiple renegotiations when using either
 bufferevents or not?

 Issues:

 In the comment:
 {{{
 +    /* Call tor_tls_got_server_hello() for every SSL ServerHello we
 +       send. */
 }}}
 I think there's a mismatch between the comment and the code.  We're about
 to call got_server_hello.  But maybe we should instead be calling a
 function called got_client_hello or sending_server_hello?

 Next: the tor_assert(tls->server_handshake_count == 2); makes me nervous.
 I don't have enough confidence there to make sure it can never be
 triggered.  Can we change it to a BUG warning?


 Next: in the last patch on that branch, should tor_tls_handshake() get a
 check here, just like read and write have?

 Last: needs a changes file.
