start on some network boot blocks. they work, but: (1) the if_prom code needs to be cleaned up quite a bit (right now it hard-codes client's ethernet address), and (2) much of this code (esp: getsecs.c, netboot.c, newvers.sh, rpcc.S) should be shared with other Alpha boot blocks, and dev_net.[ch] should maybe go in libsa proper.
