Note which network boot protocol we're trying.

- Enable NFS_BOOT_DHCP (as well as the existing NFS_BOOT_BOOTPARAM).
DHCP/Bootp is tried before bootparams in the MI nfs mountroot code.
- Change the order in boot.net from "bootparams then bootp" to
"bootp then bootparams", to be consistent with the MI nfs mountroot code.

(Consistency with other NetBSD ports is good, and things still work
for sites that run bootparams but not dhcp/bootp, although I'd argue that
dhcp/bootp is much easier to setup and manage and is easier to debug
than our rpc.bootparamd...)

Add support to the 2nd stage boot loader for booting from RAID
partitions. We do this by checking the NetBSD label to see if the
boot partition is of type RAID. If so, we offset reads from the
disk so that the kernel image can be read.

Note that with this code, sun4 machines (with PROM monitor) will only
boot from RAID if the RAID partition is the first one on the disk.
