Introduce a new init routine for plugins, which does not take the plugin api table as an argument and allows etheral to distinguish between plugins using the old and the new api. Update README.plugins accordingly Change all g_warnings() in epan/plugins.c to report_failue(). On windows we do not have a log console open while loading the plugins, because a log console cannot be opened before the prefs have been read. Thus g_warnings() does not work for reporting problems with plugins. svn path=/trunk/; revision=13596
