audio mode load: gracefully handle mode files of wrong AEC version Unfortunately our change of enabling L1_NEW_AEC (which is necessary in order to bring our Calypso ARM fw into match with the underlying DSP reality) brings along a change in the audio mode file binary format and file size - all those new tunable AEC parameters do need to be stored somewhere, after all. But we already have existing mode files in the old format, and setting AEC config to garbage when loading old audio modes (which is what would happen without the present change) is not an appealing proposition. The solution implemented in the present change is as follows: the audio mode loading code checks the file size, and if it differs from the active version of T_AUDIO_MODE, the T_AUDIO_AEC_CFG structure is cleared - set to the default (disabled AEC) for the compiled type of AEC. We got lucky in that this varying T_AUDIO_AEC_CFG structure sits at the end of T_AUDIO_MODE!
