Code bridge for Multinet

To operate with the SRI "Multinet" TCP implementation, you need a file NET_SRI.OBJ which is currently in vxcern::disk$d1:[rpc.rts.c] . This converts the calls to the network read, write and close routines into the socket_xxx names which they have in the SRI library.

The easiest way to do this is to put that object module into your local copy of the RPC$LIBC and RPC$LIBC8K libraries.
