d5127ebdd8 Fix connecting the stdin of tor-fw-helper to /dev/null 
This wasn't working due to the parameters of dup2 being in the wrong order.
As a result, tor-fw-helper was inheriting the stdin of Tor.

8fa4450fde Do not invoke tls_renegotiated_cb for non-bufferevent connections too early. 
This is not the most beautiful fix for this problem, but it is the simplest.

Bugfix for 2205.  Thanks to Sebastian and Mashael for finding the
bug, and boboper/cypherpunks for figuring out why it was happening
and how to fix it, and for writing a few fixes.

12fa6e23cb Improve fairness when activating streams in circuit_resume_edge_reading_helper 
The reason the "streams problem" occurs is due to the complicated
interaction between Tor's congestion control and libevent. At some point
during the experiment, the circuit window is exhausted, which blocks all
edge streams. When a circuit level sendme is received at Exit, it
resumes edge reading by looping over linked list of edge streams, and
calling connection_start_reading() to inform libevent to resume reading.
When the streams are activated again, Tor gets the chance to service the
first three streams activated before the circuit window is exhausted
again, which causes all streams to be blocked again. As an experiment,
we reversed the order in which the streams are activated, and indeed the
first three streams, rather than the last three, got service, while the
others starved.

 Our solution is to change the order in which streams are activated. We
choose a random edge connection from the linked list, and then we
activate streams starting from that chosen stream. When we reach the end
of the list, then we continue from the head of the list until our chosen
stream (treating the linked list as a circular linked list). It would
probably be better to actually remember which streams have received
service recently, but this way is simple and effective.
