[channels.c channels.h servconf.c servconf.h sshd_config.5] 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@

[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@.

[auth-options.c auth-options.h channels.c channels.h clientloop.c] [misc.c misc.h readconf.c readconf.h scp.c servconf.c servconf.h] [serverloop.c sftp.c ssh.1 ssh.c ssh_config ssh_config.5 sshconnect.c] [sshconnect.h sshd.8 sshd_config 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. ok djm@, markus@, jmc@ (manpages), tested and discussed with others
