Based on a work-around by Alex Zhukov.

Fixes ticket #935

When the length is the escape value (15), the new length is calculated by
15 + get_bits(8) - 1.

There is only one stream, so it will always be index 0.
This also allows for removal of the private context.

also allows for removing some unused context fields

also allows for removing some unused context fields

Time stamps are not read from the bitstream, so no wrapping is needed.

Fixes decoding of the handful of "death scream" samples from
"Command and Conquer" that use SND1. e.g.
http://samples.libav.org/game-formats/westwood-aud/nuyell1.aud
http://samples.libav.org/game-formats/westwood-aud/nuyell7.aud

Stereo ADPCM IMA WS is planar for VQA version 3 and 2-sample interleaved for
VQA version 2.

The stereo layout and extradata is significantly different from that in
Westwood IMA ADPCM, so a separate codec_id is warranted.

Fix setting of bit_rate and bits_per_coded_sample.
Ask for sample for unsupported VQA versions.

According to Multimedia Wiki documentation, the frame rate is not always 15,
and the actual value can be found in the header.

Also remove unused context field, audio_frame_counter.

The format has no coded timestamps and must use packet durations to generate
them.

Although it has been deprecated for a long time, its intended
replacement (request_channel_layout) is not actually used anywhere, so
request_channels is currently the only way to access that functionality.

It has been deprecated only recently.

It has been deprecated only recently.

Error recognition flags can and should be set directly with AVOptions.
