* [INI] Fix memory leaks + other fixes * Add ini_free * check and return if NULL pointer in free() * Add button check with timeout * Fix a bug in menu rendering that tries to parse a string without existing * Change initial cnt value to max (fixes menus with first entry not a selectable entry) * Some & ? clarifications * [INI] Add get selected boot cfg - This allows to free ini as we launch the firmware and have the lowest mem leak * [INI] Rename ini section clone/free functions
