Patch 2: see the attached `0003_use-correct-raw-audio-block-size-after-16bit-conversion.patch`.

I have tested and found that the bug affects decoding of 8-bit sterero
RAW PCM sound in the same way. So this additional patch fixes the same issue
within RAW PCM decoder.

(file #34873)

Currently Gnash (GStreamer media handler) has a problem on playing
8-bit stereo PCM embeded sound. This was due to wrong output size
was given out by the decoder when the sound is stereo.

This patch fixes this issue by correcting the buffer size multiplier used
when the decoder converts 8-bit to 16-bit PCM, which is supposed to be `2`.
(Original code used `4` if the sound is stereo, which it shouldn't, since
stereo expansion and further size multiplication, are done separately).

See the attached `0002_use-correct-audio-block-size-after-16bit-conversion.patch`.

Note: This fix does not cover FFmpeg/libAV media handler.
