Generally, libavformat exports cover art pictures as video streams with
1 packet and AV_DISPOSITION_ATTACHED_PIC set. Only matroskadec exported
it as attachment with codec_id set to AV_CODEC_ID_MJPEG.

Obviously, this should be consistent, so change the Matroska demuxer to
export a AV_DISPOSITION_ATTACHED_PIC pseudo video stream.

Matroska muxing is probably incorrect too. I know that it can create
broken files with an audio track and just 1 video frame when e.g.
remuxing mp3 with APIC to mkv. But for now this commit does not change
anything about muxing, and also continues to write attachments with
AV_CODEC_ID_MJPEG should the muxer application have special knowledge
that the Matroska is broken in this way.

Fixes trac #4423.

ER with slice threads is buggy and since the merge of the libav cleanup broken
as the ER context which is supposed to be per frame has been placed in
the slice context, so there are multiple per frame which does not work as is.

Theres no bug report about ER with frame threads. If someone knows of a
case where it crashes / fails without slice threads please mail me and
open a ticket on trac.

The way it is currently designed is fundamentally unsafe and cannot be
reasonably fixed without completely rewriting it.

Since we are not doing encoding, there is no point in ever touching the
separate encoding context. Always use the stream codec context.

Fixes writing attachments.

This is the same as is done for SPS.

This allows the callers to have a hint of the probable stream parameters
without actually decoding anything.

Additionally always set the software pixel format, so it's available
even if ff_get_format() is not called later. This will be useful for
exporting stream parameters from init().

Make sure we don't buffer up more than max_delay worth of data
before writing a PES packet, even if pes_payload_size is set to
a larger value.
