Every connection has a poll callback handler. This is great 
when there is a live connection.

There are times we need some kind of server timing. I found one situation that
this is very much needed but I am sure it can be very useful in other
situations as well.

In cases were we need to keep track over user session ID's like in HTTP
sessions we cannot use the connection pcb as it will be closed after the
transaction is closed. I had to create a separate task that handles those
session ID's !

Adding poll callback to server own pcb will give a simple mechanism to keep
track over session ID's timeouts.

If not too much to to ask please add a poll callback to the server pcb as
