acb074301c avio: Only do implicit network initialization for network protocols
The implicit network initialization is set to be removed in the
future, but is kept for compatibility. By not doing the implicit
initialization for non-network protocols, we avoid the warning
about avformat_network_init() not being called for these, where
it really doesn't make much sense.

4278023240 Check for overread in vqa video decoder.
This issue was discovered while decoding the FATE sample vqa/ws_snd.vqa.
For some unknown reason only audio decoding is tested by FATE for that file,
but not video.

1d0d63052b sipr: fall back to setting mode based on bit_rate.
Not all applications (e.g. MPlayer) set block_align, and
when using a different demuxer it might not even be
easily available.
So fall back to selecting mode based on bit rate as before
if block_align has not useful value.
It can't be worse than failing to decode completely.
