Subject: Implement the core v3 plug-in function calls.
X-Git-Tag: v2.3-alpha1~266
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=76b41d7f69853b07d2a32d7179136b2781dcedf8;p=thirdparty%2Fopenvpn.git

Implement the core v3 plug-in function calls.

Let OpenVPN call the openvpn_plugin_open_v3() and
openvpn_plugin_func_v3() plug-in functions if they exist in the plug-in.
