S.N. Hemanth Meenakshisundaram c1db7bff66 Resize data and linesize in AVFilterBufferRef to 8.
This is required to make AVFilterBufferRef able to contain also audio
data, required by audio filtering integration.

S.N. Hemanth Meenakshisundaram 9f08d80363 Add av_picture_data_copy() and reimplement av_picture_copy() as a
wrapper of it.

The new function is more generic, and does not depend on the
definition of the AVPicture struct.

S.N. Hemanth Meenakshisundaram cc80caff52 Separate video specific BufferRef properties into VideoProps.
Define a new struct AVFilterBufferRefVideoProps and add a type field
to AVFilterBufferRef.

Video specific properties in AVFilterBufferRefVideoProps are now
referred to by *video pointer in AVFilterBufferRef.

S.N. Hemanth Meenakshisundaram 5d4890d73d Rename fields:
AVFilterLink.srcpic    ->  AVFilterLink.src_buf
AVFilterLink.cur_pic   ->  AVFilterLink.cur_buf
AVFilterLink.outpic    ->  AVFilterLink.out_buf

The new names are more generic and more consistent, since the struct
they contain, which was named AVFilterPicRef, has been renamed to
AVFilterBufferRef.

avfilter_(un)ref_pic       -> avfilter_(un)ref_buffer
avfilter_copy_picref_props -> avfilter_copy_buffer_ref_props
AVFilterBufferRef.pic      -> AVFilterBufferRef.buffer

They have been renamed to allow sharing with audio.

S.N. Hemanth Meenakshisundaram ecc8dada37 Rename AVFilterPicRef to AVFilterBufferRef.
The struct is going to be used for storing audio buffer references as
well, and the new name is more generic.

S.N. Hemanth Meenakshisundaram 59ff3fd536 Fix the size of the data to be copied from an AVFilterBuffer to an
AVFilterBuffereRef in avfilter_default_get_video_buffer().

The error was being caused by the previous patch which resized
AVFilterBuffer's data and linesize arrays to 8.

S.N. Hemanth Meenakshisundaram 9dd9d67bd0 Define static functions fill_image_linesize() and
fill_image_data_ptr(). ff_fill_linesize() and ff_fill_pointer() now wrap
these functions.

The new functions are more generic, and are going to be exported in a
future patch.

S.N. Hemanth Meenakshisundaram bdab614be8 Generalize pixel format enum fields to int formats.
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.

S.N. Hemanth Meenakshisundaram ff5f1be0fe Move the AV_PERM_* flags definition outside the AVFilterPicRef
definition.

This way it is easier to reference them in other structures, for
example in the pending AVFilterSamplesRef struct.

S.N. Hemanth Meenakshisundaram b5c582fa9d Remove AVFilterBuffer w and h fields.
These fields are never used, and they do not seem to belong to
AVFilterBuffer anymore, now that it is now a media-independent
structure and these fields are video-related.

The struct is going to be used for audio data as well, so the new name
is less misleading.
