527ca3985c lavfi: use int64_t lists in AVFilteFormats
The list type was changed to int64_t to be able to hold
channel layouts.

avfilter_make_format_list() still takes a int32_t array and converts
it to int64_t. A new function, avfilter_make_format64_list, that
takes int64_t arrays has been added.

8f349b6481 lavfi: fix realloc size computation in avfilter_add_format()
Replace sizeof((*avff)->formats)
with    sizeof(*(*avff)->formats)

as the size of the array element is given by the pointed element
rather than by its pointer.

In particular fix computation with the pending patch when
sizeof(int64_t) != sizeof(int64_t *).

64c06615d2 vsrc_buffer: simplify av_vsrc_buffer_add_frame*() interface
Now that pix_fmt, width, and height are directly embedded in the AVFrame,
there is no need to pass these values as separate arguments.

566666caf3 lavfi: add libavfilter/avcodec.h and avfilter_copy_frame_props()
avfilter_copy_frame_props() avoids code duplication and increases
robustness.

The added files libavfilter/avcodec.[ch] are used for containing

18ded93ab3 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.
