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.
