This is required for the pending lavfi indev extension, also
consistent with the video buffer sink.

Allow factorization for the pending work on the audio movie source.

Getting rid of globals are generally a good thing. The patch also makes
toggle_pause and step_to_next_frame use a function parameter instead of
the global cur_stream variable.

Add the sar option. Useful for debugging/testing purposes.

This fixes the situation when there are not enough entries in the index
(e.g. on initial seek there's only one index entry in the index) and index
search returns just the last known entry. That causes seeking function just to
seek there instead of trying harder to get at the requested position.

Currently for multichannel audio position for the last block position is
stored in index (and used for seeking), which is obviously not correct.

Useful for debugging.

Avoid code duplication.

Due to it in contrast to the decoder not setting up low_delay,
the code in parse_nal_units would always end up setting has_b_frames
to 1 (except when stream is explicitly marked as low delay).
Since the parser itself would create extradata, simply reopening
the parser would cause this.
estimate_timings_from_pts would cause the parser to be reopened
on the same stream.

This fixes trac issue #360.
