Handle stale sockets to the master session

Sometimes when the session is ended, the file-socket is not removed.
This prevents the user to do a detach. (Actually the session has
already detached but the TunnelSetup was not aware of it)
Added dynamic SOCKS server support

Changed the config file to use socksStart,socksEnd and socksActive,
instead of proxy variable.
Updated Linux-64 build
