Allow to specify the display aspect ratio adopted for rendering
subtitles.

Previously it was using the same value of the input video DAR, which is
inconsistent with most implementations.

Fix trac ticket #1098.

Check on < 0 rather than on != 0, this is more correct as a positive
error code from av_parse_ratio() value doesn't mean an error.

Fixes a memleak when using the -frames option with audio.

Fixes Ticket1109

There is no reason for it to be public, it's only meant to be used
internally.

The caller can achieve the same effect (i.e. getting raw unparsed/mangled
packets) with av_read_frame() and AVFMT_FLAG_NOPARSE |
AVFMT_FLAG_NOFILLIN

Takes encoder delay into account by comparing first the coded page
duration with the calculated page duration. Handles last packet duration
if needed, also by comparing coded duration with calculated duration.
Also does better handling of timestamp generation for packets in the
first page for streamed ogg files where the start time is not
necessarily zero.

5 FATE test references updated due to using demuxer-generated timestamps that
are either not sample-accurate or are slightly off in the input file.

Also fixes stream duration calculation.

The values in the header refer to decoded data, not compressed data.

Do not output an extra packet when out_size is reached.
Also return AVERROR_EOF instead of AVERROR(EIO).

The packet duration is always 28 samples.

This fixes decoding of Bink files with non-multiple-of-16 width.

This enables reordering of UDP packets by default, unless the caller
explicitly sets -max_delay 0.
