The code that checks whether the router advertisments contain only
a link-local address has a bug: It must check the full first 10 bits
of the address, not only the first 9 bits. Otherwise, site-local
addresses (which start with 0xFEC0...) are also recognized as
link-local, which is wrong, of course.
Fix it by also introducing a proper wrapper functions for link-local
addresses (which will be used in a later patch, too).

This patch adds support for booting from a IPv6 network. It gets the boot information
(tftp server, boot file name) from DHCPv6 server or can be specified manually using
obp-tftp arguments. To boot from a IPv6 network, type "boot net:ipv6" from the SLOF
prompt. To specify ipaddresses manually, type "boot net:ipv6,<si6addr>,<filename>,<ci6addr>"
from the SLOF prompt.
This patch is based on the IPv6 code written by the former SLOF team.
