[readconf.c readconf.h ssh.1 ssh_config.5 sshconnect.c]
Move SSH Fingerprint Visualization away from sharing the config option
CheckHostIP to an own config option named VisualHostKey.
While there, fix the behaviour that ssh would draw a random art picture
on every newly seen host even when the option was not enabled.

Do not pass "0" strings as ports to getaddrinfo because the lookups
can slow things down and we never use the service info anyway. bz
#859, patch from YOSHIFUJI Hideaki and John Devitofranceschi. ok
deraadt@ djm@
djm belives that the reason for the "0" strings is to ensure that
it's not possible to call getaddrinfo with both host and port being
NULL. In the case of canohost.c host is a local array. In the
case of sshconnect.c, it's checked for null immediately before use.
In dns.c it ultimately comes from ssh.c:main() and is guaranteed to
be non-null but it's not obvious, so I added a warning message in
case it is ever passed a null.

Introduce SSH Fingerprint ASCII Visualization, a technique inspired by the
graphical hash visualization schemes known as "random art", and by
Dan Kaminsky's musings on the subject during a BlackOp talk at the
23C3 in Berlin.
Scientific publication (original paper):
"Hash Visualization: a New Technique to improve Real-World Security",
Perrig A. and Song D., 1999, International Workshop on Cryptographic
Techniques and E-Commerce (CrypTEC '99)
http://sparrow.ece.cmu.edu/~adrian/projects/validation/validation.pdf
The algorithm used here is a worm crawling over a discrete plane,
leaving a trace (augmenting the field) everywhere it goes.
Movement is taken from dgst_raw 2bit-wise. Bumping into walls
makes the respective movement vector be ignored for this turn,
thus switching to the other color of the chessboard.
Graphs are not unambiguous for now, because circles in graphs can be
walked in either direction.

Add support for tun(4) forwarding over OpenSSH, based on an idea and
initial channel code bits by markus@. This is a simple and easy way to
use OpenSSH for ad hoc virtual private network connections, e.g.
administrative tunnels or secure wireless access. It's based on a new
ssh channel and works similar to the existing TCP forwarding support,
except that it depends on the tun(4) network interface on both ends of
the connection for layer 2 or layer 3 tunneling. This diff also adds
support for LocalCommand in the ssh(1) client.
