Comment(by nickm):

 As noted, RECV_OBFS2_PENDING should probably be called RECV_SEND_PENDING
 or something.  It's something that other protocols can return too, right?

 C tip: the cast here is redundant:
 {{{
 +  if (evbuffer_add_buffer(dest,source)<0)
 +    return (enum recv_ret) RECV_BAD;
 +  else
 +    return (enum recv_ret) RECV_GOOD;
 }}}
 RECV_BAD and RECV_GOOD are already of the type you need, and adding extra
 casts makes it look like you're doing something dangerous when really it's
 all good.

 The comment on obfs2_recv is now wrong.

 The RECV_BAD_WAIT patch makes no sense to me.  What is it for?  Why can't
 we just close the connection?
