+ * dict_get_str_boolean - get a boolean value based on string representation.
+ *
+ * @this : dictionary
+ * @key : dictionary key queried
+ * @default_val : default value if key not found
+ *
+ * @return : @default_val if key not found
+ * : boolean interpretation of @this[@key] if it makes sense
+ * (ie., "on", "true", "enable" ...)
+ * : -1 if error occurs or @this[@key] doesn't make sens as
+ * boolean
+ *
+ * So if you query a boolean option, then via @default_val you can choose
+ * between following patterns:
+ *
+ * - fall back to _gf_false if @key is not set [@default_val = 0]
+ * - fall back to _gf_true if @key is not set [@default_val = 1]
+ * - regard as failure if @key is not set [@default_val = -1]
+ * - handle specially (not as error) if @key is not set
+ * [@default_val = anything else]
