Allow connections where maxIdleTime is <= 0 to never expire

From the mailing list:

We're trying to get jetty to honor an unlimited max idle connection
timeout (e.g. we don't want connections to timeout). I've looked at the
code and it appears that in AbstractConnector jetty does honor a value
of '0' to the socket timeout, e.g.:

protected void configure(Socket socket)
throws IOException
{
try

{ socket.setTcpNoDelay(true); if (_maxIdleTime >= 0) socket.setSoTimeout(_maxIdleTime); if (_soLingerTime >= 0) socket.setSoLinger(true, _soLingerTime/1000); else socket.setSoLinger(false, 0); }

catch (Exception e)

{ Log.ignore(e); }

}

Note:

if (_maxIdleTime >= 0)
socket.setSoTimeout(_maxIdleTime);

However, there is also a Timeout object that uses this maxIdleTime
setting as well in SelectorManager. The relevant Timeout code is in
Timeout.java (I think):

public Task expired()
{
long _expiry = _now-_duration;

if (_head._next!=_head)
{
Task task = _head._next;
if (task._timestamp>_expiry)
return null;

task.unlink();
synchronized (task)

{ task._expired=true; }

return task;
}
return null;
}

_duration is what maxIdleTime is set to. This would appear to make the
expiry happen immediately
