The reference encoder does not generate any streams using this, but the
reference decoder can handle it, so we should as well.

This isn't used by the reference encoder, but it is supported by the decoder.

Now that there is official documentation from Apple about this, we don't have
to guess anymore.

The original code wasn't taking into account the fact that linesize may not equal the frame's width.  This is to correct that.

Up until now, the decoder didn't output anything
in the data buffer. This fixes all the issues
related to sample format, removes leftover code
and actually outputs some audio to data buffer.

With this, the only sample we have can be played.
Seeking is still broken though.

Adds a new member to MpegEncContext to hold the number of used slice
contexts. Fixes segfaults with '-threads 17 -thread_type slice' and
fate-vsynth{1,2}-mpeg{2,4}thread{,_ilace} with --disable-pthreads.

Fixes Ticket856
