Retrieve directory list from environment variables
This adds a function able to retrieve from a prefix and suffix an environment variable. This is meant to search config or plugin files from potentially several sources, environment and source code. This tries to get 2 environments variables: - prefix+binderName+suffix (eg: AFT_LOWCAN_CONFIG_PATH) - prefix+suffix (eg: AFT_CONFIG_PATH) Then it returns the one found or both if they exist with the most accurate one (with the binder name) first followed by the other.
