Pull lingering close out of the pool cleanup phase. This was causing too

many bugs.  Instead, it is called where it used to be called.  I have
abstracted some of the logic out of the lingering close so that it gets
the socket from the connection using the core's conn_config vector.  This
is in anticipation of a change to use a hook for the lingering close,
which I hope to do soon.
