Fixed problem with an unresponding device after playing specific WAV files.
WAV files encoded with ADPCM are not supported now by the devices.

[CP-1837] Random crashes while copying files

Use ConstMemoryConstrainedFileRef newly added to taglib

[MOS-878] Don't break audio playback on file deletion

Since a currently played file is deleted, the player

Fixed iosyscalls so that Pure simulator
works after directory structure 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.
