A patch series adding seek support to libavformat/aadec.

This fourth version of the series addresses some more comments from the
mailing list:

Patch 2/3 now uses avpriv_set_pts_info(). Otherwise, it is still based on
skipping through the content to collect chapter boundaries. This is not
optimal, but the actual aa "index" is not understood well enough to be usable
at this time.

Patch 3/3 was completely reworked; it does not scan for mp3 headers anymore,
which was unreliable and broke the separation of demuxer and codec. It now
simply predicts the header offset, which works for the majority of tested
audio material, while the effect on rare divergent material is negligible.

Karsten Otto (3):
  aadec: improve eof detection
  aadec: add chapters and seeking
  aadec: improve seeking in mp3 content
