Kostas Missos b2dd070d10 [INI] Fix memory leaks + other fixes (#38)
* [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
