Fix critical bugs in session opening for TCP and UDP in case of Singleplex mode. (#145) 
* Fix critical bugs in session opening for TCP and UDP in case of Singleplex mode.

- In case of TCP, don't open the session in the listener accept thread. This
  causes resource exhaustion of the tcp listener backlog queue in case of internet
  connection disruption or timeout.

- In case of UDP, don't create a new session for every UDP packet.

* Fix race in integration test.

* Fix race condition in session maker

* Code style improvements

* Explicit session.Close() call is indeed needed

Fix regression: termination of long downloads after StreamTimeout seconds (#141) 
* Fix termination of long downloads after StreamTimeout seconds.

- Even if not broadcasting in a loop, we still need to update the read deadline.
- Don't enforce the timeout after the first data is written.

* When timeout no longer needs to be enforced, no need to schedule a broadcast.

* Fix Cloak client. Don't enforce read deadline after first read.

* Enforce StreamTimeout on the initial bytes sent by localConn only.

* Revert changes to multiplex module. Remove timeout from caller.
