s3:rpc_server: Add a function to create the endpoints sockets

The pidl-generated initialization function for each endpoint server will
register the RPC interface in all endpoints defined in the idl file.

The interface registration code will create the endpoint if it does not
exists (as an endpoint can serve multiple interfaces) and will add it to
the endpoint list exiting in the dcesrv_context.

This commit adds a generic dcesrv_create_endpoint_sockets function which
will be preforking external daemons to create the sockets regardless the
endpoint transport. This function will only create the sockets, the
external preforking daemon is who will start listening.
