Move C/R -> kbdint special case to after the defaults have been
loaded, which makes ChallengeResponse default to yes again. This
was broken by the Match changes and not fixed properly subsequently.

Remove ChallengeResponseAuthentication support inside a Match
block as its interaction with KbdInteractive makes it difficult to
support. Also, relocate the CR/kbdint option special-case code into
servconf. "please commit" djm@, ok markus@ for the relocation.

Make PermitOpen take a list of permitted ports and act more like most
other keywords (ie the first match is the effective setting). This
also makes it easier to override a previously set PermitOpen. ok djm@

Add ForceCommand keyword to sshd_config, equivalent to the "command="
key option, man page entry and example in sshd_config.
Feedback & ok djm@, man page corrections & ok jmc@
[channels.c channels.h servconf.c sshd_config.5]
Add PermitOpen directive to sshd_config which is equivalent to the
"permitopen" key option. Allows server admin to allow TCP port
forwarding only two specific host/port pairs. Useful when combined
with Match.
If permitopen is used in both sshd_config and a key option, both
must allow a given connection before it will be permitted.
Note that users can still use external forwarders such as netcat,
so to be those must be controlled too for the limits to be effective.
Feedback & ok djm@, man page corrections & ok jmc@.
[sshd.c servconf.h servconf.c sshd_config.5 auth.c]
Add support for conditional directives to sshd_config via a "Match"
keyword, which works similarly to the "Host" directive in ssh_config.
Lines after a Match line override the default set in the main section
if the condition on the Match line is true, eg
AllowTcpForwarding yes
Match User anoncvs
AllowTcpForwarding no
will allow port forwarding by all users except "anoncvs".
Currently only a very small subset of directives are supported.

two changes to the new ssh tunnel support. this breaks compatibility
with the initial commit but is required for a portable approach.
- make the tunnel id u_int and platform friendly, use predefined types.
- support configuration of layer 2 (ethernet) or layer 3
(point-to-point, default) modes. configuration is done using the
Tunnel (yes|point-to-point|ethernet|no) option is ssh_config(5) and
restricted by the PermitTunnel (yes|point-to-point|ethernet|no) option
in sshd_config(5).

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.

[sshconnect2.c sshd.c sshd_config sshd_config.5]
add a new compression method that delays compression until the user
has been authenticated successfully and set compression to 'delayed'
for sshd.
this breaks older openssh clients (< 3.5) if they insist on
compression, so you have to re-enable compression in sshd_config.
