[PATCH 00/16] Cleanups and fixes related to "our" addresses

[David Gibson <david@gibson.dropbear.id.au>]

There are some places where we have addresses that are "ours" in the
sense that they're local to passt on at least one interface.  But in
some cases it wasn't clear which addresses those were or how to use
them.  Make a number of renames, cleanups and small fixes related to
that.

..and also an assortment of slightly related things that I encountered
along the way.

Note that 1/16 is an important fix for a bug I introduced in the last
series I sent.  For the rest, apply as many as you're happy with and
I'll respin what's left as necessary.

David Gibson (16):
  conf: Don't ignore -t and -u options after -D
  treewide: Use "our address" instead of "forwarding address"
  util: Helper for formatting MAC addresses
  treewide: Rename MAC address fields for clarity
  treewide: Use struct assignment instead of memcpy() for IP addresses
  conf: Use array indices rather than pointers for DNS array slots
  conf: More accurately count entries added in get_dns()
  conf: Move DNS array bounds checks into add_dns[46]
  conf: Move adding of a nameserver from resolv.conf into subfunction
  conf: Correct setting of dns_match address in add_dns6()
  conf: Treat --dns addresses as guest visible addresses
  conf: Remove incorrect initialisation of addr_ll_seen
  util: Correct sock_l4() binding for link local addresses
  treewide: Change misleading 'addr_ll' name
  Clarify which addresses in ip[46]_ctx are meaningful where
  Initialise our_tap_ll to ip6.gw when suitable
