When printing the interface name from the ipstate_t struct the interface
name in is_ifp may not always be avaiable when reading it from kmem
(tested on FreeBSD and NetBSD). However the is_ifname (the interface
name character string) is almost always available -- it is not available
when the source of the packet is a process running on the firewall
itself. Rather than print both interface name strings, print only the
one.

Rather than use a kmem read to determine the interface name used by a
nat_t structure through a pointer, nat_ipfs->netif->if_xname, obtain it
directly from nat_ifnames in the nat_t structure itself using the new
FORMAT_IF macro.

Interface names stored in the ipstate_t and ipnat_t structures can be
NULL. This occurs when an application, such as named, is running on the
firewall machine itself. For example an application, i.e. named, running
on the firewall itself will cause a state table display and NAT mapping
display to show a null ingress interface and its egress interface. This
is perfectly valid but confusing to human eyes. Rather than print
nothing, print "(null)".

VGA hardware provides many different graphics and data access modes,
each with different capabilities and limitations.
VGA vt(4) graphics mode operates on blocks of pixels at a time. When a
given pixel block contains only two colours the vt_vga driver uses write
mode 3. When the block contains more than two colours it uses write
mode 0. This is done because two-colour write mode 3 is much more
efficient.
In practice write mode 3 is used most of the time, as there is often a
single foreground colour and single background colour across the entire
console. One common exception requiring the use of mode 0 is when the
mouse cursor is drawn over a background other than black, as we need
black and white for the cursor in addition to the background colour.
VGA's default 16-colour palette provides the same set of colours as the
system console, but in a different order. Previously we configured a
non-default VGA palette that had the same colours at the same indexes.
However, this caused anything drawn before the kernel started (drawn by
the loader, for instance) to change colours once the kernel configured
the new, non-default palette.
In 5e251aec86 we switched to leaving the default VGA palette in place,
translating console colour indexes to VGA colour indexes as necessary.
This translation was missed for the write mode 0 case for pixel blocks
with more than two colours.

Just as pfctl already does for other rules we print the ethernet rules
we would have loaded if '-n' is specified.
Sponsored by: Rubicon Communications, LLC ("Netgate")
When filtering Ethernet packets allow rules to specify a mac address
with a mask. This indicates which bits of the specified address are
significant. This allows users to do things like filter based on device
manufacturer.
