[PATCH 0/4] [vpnc-script] Support for Pulse's split-exclude routes

[Gernot Hillier]

OpenConnect already sets the according environment variables when the Pulse
gateway sends "split-exclude" routes, so we only need to handle them
in vpnc-script. 

I hope this is the right place for vpnc-script patches.

While this is basically trivial copy-n-paste code duplication, we need some
preparation for script's infrastructure as it now needs to handle routes to your
normal Internet uplink device in addition to your VPN tunnel.

Implemented and tested for "ip-route" as well as old-fashioned /sbin/route mode
of vpnc-script - so now your dream to have a Pulse VPN connection with
split-exclude routes on your ancient embedded device can become reality!

Please let me know if you prefer a different patch splitup, removal of untested
IPv6 code or similar!
