NetBSD/cobalt 5.1_RC4 restorecd

Hi,

5.1_RC4 binaries seem ready on ftp.NetBSD.org,
so I've built and put 5.1_RC4 based NetBSD/cobalt restorecd:
http://ftp.NetBSD.org/pub/NetBSD/arch/cobalt/restore-cd/5.1_RC4/

No particular changes restorecd installation procedure itself.
Briefly tested on Qube 2 with an old ThinkPad as i386 server.

See also "Restore CD Howto" for details:
http://www.NetBSD.org/ports/cobalt/restorecd-howto.html

Generic updates/fixes on 5.1_RC4 (since previous RC2 one) can be found in:
http://ftp.NetBSD.org/pub/NetBSD/NetBSD-5.1_RC4/CHANGES-5.1
http://cvsweb.NetBSD.org/bsdweb.cgi/src/doc/Attic/CHANGES-5.1.diff?r1=1.1.2.231&r2=1.1.2.244

Some highlights:
 - disklabel(8) fix for >1TB disks (in RC3)
 - fix openssl CVE-2010-2939
 - fsck_ffs(8) bug fix (it didn't possibly replay WAPBL journal)
 - fix ipfilter mbuf corruption on IPv6 ICMP etc.
 - sort(1) segfaults fix on large input
  etc.

Following ones may affect i386 server:
 - NVidia EHCI workaround (in RC3)
 - Core i7 CPU detection workaround

If you see any problem, please report here or via send-pr(1).
