We already call the configured script with 'reason=disconnect'. Although
we do that for *any* disconnection, and we don't provide the reason.

It wouldn't be hard to make openconnect provide the reason....

diff --git a/tun.c b/tun.c

 		if (vpninfo->vpnc_script) {
 			setenv("reason", "disconnect", 1);
+			setenv("CISCO_DISCONNECT_REASON", vpninfo->quit_reason, 1);
 			if (system(vpninfo->vpnc_script) == -1) {
 				vpninfo->progress(vpninfo, PRG_ERR,
 						  "Failed to spawn script '%s': %s\n",

However, before changing the interface to vpnc-script by adding a new
variable like this, we should talk to vpnc folks and see if they want to
add something similar.

It would be useful to make NetworkManager use this extra reason string
too -- currently, you just get a pop-up saying the connection failed,
without any indication of why it really disconnected.
