Add a counter : "enabled_plugins_number", to record how many plugins are

enabled. The counter is incremented in enable_plugin() and decremented
in disable_plugin().
In add_packet_to_packet_list(), we check this counter (instead of
plugin_list) to see if there is at least one enabled plugin. If this is
the case, we must build the protocol tree.
