* routeSockLibInit - intialize the routing socket interface

* This function intializes the routing socket interface. It initializes
* the routing domain and then intializes the protocol switch. This function
* should be called only at network initialization time, after domaininit()
* and route_init(). There is only one protocol in the protocol switch to
* enable routing sockets.
