libeplayer3: add aac_adtstoasc bitstream filter

Browse Source 
Add the aac_adtstoasc bitstream filter for AAC streams. In the
cases where it is not needed, it does not seem to hurt, and in
other cases it fixes audio playback.
TODO: improve the handling of the bsfc allocation / deallocation,
      this should go in a Track() destructor or similar.
