6e9bb5aa3e swscale: prevent invalid writes in packed_16bpc_bswap
Writes past the end of the destination buffer were occuring when its
stride was smaller than the stride of the source. Fixes Bug #183.

8a4a5f6ff7 lavc: add format field to AVFrame
The format is a per-frame property, having it in AVFrame simplify the
operation of extraction of that information, since avoids the need to
access the codec/stream context.

b58dbb5b03 lavc: add a sample_aspect_ratio field to AVFrame
The sample aspect ratio is a per-frame property, so it makes sense to
define it in AVFrame rather than in the codec/stream context.
Simplify application-level sample aspect ratio information extraction,
and allow further simplifications.

251f320f7d flvdec: Export new AAC/H.264 extradata as side data on the next packet
Compared to just overwriting the old extradata, this has the
advantage of letting the decoder know exactly when the
extradata changed (otherwise it is changed immediately when the
new extradata packet is demuxed, even if there's old queued packets
awaiting to be decoded). This makes it easier for decoders to
actually react to the change, so they won't have to inspect
the extradata for each packet to see if it might have changed.

This works when sequentially playing a file with sample rate
changes, but if seeking past a new extradata packet in the
file, it obviously doesn't work properly. That case doesn't
work in flash player either, so it's probably ok not to handle
it.
