network: add timeout for client connections

Browse source 
Somtimes client connetions will not close therfore add a timeout. Add a
new timer that checks every 5s if we did not receive anything from a
client for (default) 60s. Can be configured via client_timeout.

Code is based on the work of ptpt52.
