Subject: [PATCH] Improve compatibility with pppd-2.5.0 release
This allows compiling against the older pppd 2.4 series while still
using the new API in the plugin code. It does so by adding a static
inline function ppp_add_notify().
Additional formatting changes to the nm-fortisslvpn-pppd-compat.h based
on review from Lubomir.
