Use prefix variable to find controller's plugins
Prefix is the most reliable variable to find files or variables for a controller, so this lets you access it wherever it is needed without using global hardcoded variables. This helps to search for controller's plugins in several locations depending on environment variables and hardcoded variables (CONTROL_PLUGIN_PATH, CONTROL_CONFIG_PATH). This implies also a change a LUA interpreter loading step to correctly set the package.path variables with the environment variables, too. Correct the missing 'extern' in function declarations. Depends-On: Ic448ff017e6158bec05895d63688b8968b5c6434 Change-Id: I0ad19242612559d1f4b66b6f9af9e7032d4675a8 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
