config: use find_config_tree_array for all arrays

Use find_config_tree_array for all config arrays. Also, add
INTERNAL_ERROR in case there should have been at least default
value defined for a setting but it was not returned for some
reason (either config_settings.h misconfiguration or other config
tree error printed by functions called by find_config_tree_array).
