AVFilterContext *avfilter_open(AVFilter *filter, const char *inst_name);
to:
int avfilter_open(AVFilterContext **filter_ctx, AVFilter *filter, const char *inst_name);
This way it is possible to propagate an error code telling the reason
of the failure.

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.

In case of reallocation failure the pointer to the original filter
array was lost. The correct behavior seems to just keep the old array
and count.

Now the parser link the filters from the graph directly
with avfilter_link().

Functional as is, but still work-in-progress in the
sense that some things need to be fixed before sending
it as a patch to SVN.

This can now handle filters which are added to graphs out of order,
including auto-inserted scale filters. As an added bonus, it can
now detect circular filter chains which wouldn't work anyway.

This makes the code a little less confusing, and is needed for the patch to
improve the link configuration process, to be committed next.
