Yes : plugin_list is not NULL if at least one plugin is installed, even
if it is disabled. This is generally the case (make install installs the
gryphon plugin).

When I first implemented plugins, plugins where inserted in plugin_list
when they were enabled, and removed when they were disabled, so the test
was right. But now it isn't anymore.

I just checked in a change for this : a simple "enabled_plugins_number"
counter which is incremented in enable_plugin(), decremented in
disable_plugin(), and checked in add_packet_to_packet_list().
