enable CODEC_CAP_DELAY to flush any remaining frames in the buffer.

Stop decoding when the FN_QUIT command is found so that a trailing seek table
isn't decoded as a normal frame.

decode all channels in the same call to avcodec_decode_audio3() so that
decoding will not stop after the first channel of the last frame.

Updated FATE reference. More valid audio is now decoded.

decode_subframe_lpc().

just set data_size to zero.

fixes incorrect bitrate reporting and potential misreporting of the number of
channels.

Having it there forces decoding of a frame in order to get frame_size, but it
is not really needed for proper demuxing or decoding.

The first timestamp should be negative due to delay.
Also, do not set AVCodecContext.frame_size unnecessarily.

Using AVCodecContext.frame_size is not reliable.

This avoids some unused variable warnings with YASM disabled.
