[MOS-786] A/B Booting - fixed factory reset from menu

Now factory reset works both from ecoboot and from menu

[MOS-783] Fixed generating image for Harmony

Needed because of layout change

[MOS-783] Fixed Pure unit tests

Fixed (most of the) hardcoded
paths in Pure's unit tests.

[MOS-783] Working Pure simulator after partition changes

[MOS-783] First part of new dir structure implementation

    Works:
    - generating .img for Pure;
    - Pure boots after flashing new image and
    seems to be working fine;

    Not yet:
    - generating update package;
    - generating image for Harmony;
    - simulator;
    - path-related unit tests fail
    due to paths being hardcoded
    in test scenarios.

but is stripped of irrelevant data that is not required by the
MC to perform data synchronization.
