Attached patch fixes the issue in the FLV muxer and the equivalent
problem in the demuxer.
Tested with the Windows Flash browser plugin - unsigned sounds correct,
signed does not.

New submission from regits stiger1...@gmail.com:
from flv spec, pcm 8bits are unsigned.
so we need to change all CODEC_ID_PCM_S8 in
libavformat/flvenc.c to CODEC_ID_PCM_U8.
