Some converters (ie. unscaled rgb24 -> argb) may write some bytes out of
bounds. Ideally the converters should be fixed, but in the meantime we allocate
more memory to prevent heap corruption.

Not necessary with the previous patch.

Uses a slightly nonintuitive ring buffer size of (width+height*2) to simplify
addressing logic.
Also split out the segmentation map to a separate structure, necessary to
implement the ring buffer.

change of r24424.

Originally committed as revision 24425 to svn://svn.ffmpeg.org/ffmpeg/trunk

This is needed to make the libavfilter framework work with audio
filters.

In particular add a type field to AVFilterLink, change the field types:
enum PixelFormat format   -> int format   in AVFilterBuffer
enum PixelFormat *formats -> int *formats in AVFilterFormats
enum PixelFormat *format  -> int format   in AVFilterLink

and change the function signatures:
AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
AVFilterFormats *avfilter_make_format_list(const int *fmts);

int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
int avfilter_add_format(AVFilterFormats **avff, int fmt);

AVFilterFormats *avfilter_all_colorspaces(void); ->
AVFilterFormats *avfilter_all_formats(enum AVMediaType type);

This change breaks libavfilter API/ABI.

Gives better cache locality, since the VP8Macroblock structs are still in cache.
Inspired by the way x264 does it.

As in the previous commit, they aren't used for context selection, so it saves
memory this way.
