[EGD-8095] Add quote on wallpaper

[EGD-8129] Add atexit functionality

Added atexit functionality. All global destructors and functions
registered with atexit() should be called at program exit.
It was possbile to reuse original newlib implementation with
MALLOC_PROVIDED flag set.

Made sure logger destructructor is called as last one.

Due to mudita OS legacy, it was not possible to simply fix dependencies
in global objectes and hence there are neither global objects
destructors nor functions registered with atexit() called when exit()
is called.
Possibly it will be changed later.
