Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it
and use AVFrame instead.

Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

A number of compilers, for example those from TI and IBM, choke on
these initialisers.  The current style is also quite ugly.

This reduces code duplication and prevents stale pointers from remaining
on the link.

It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.

It will allow adding new fields to it without ABI breaks.

They are only useful inside filters and we don't allow user filters for
now.

This fixes the following warning:
libavfilter/vf_unsharp.c:106: warning: initialization discards qualifiers from pointer target type

The previous default value 0x0 was not good, since it is not even
valid.

In apply_unsharp(), when y is >= height, prevent out-of-buffer reading
from src, read from the last buffer line in src2 instead.

The check was implemented in the original unsharp libmpcodecs code and
lost in the port.

This also fixes output discrepancy between the two filters.

Also drop obfuscating CHROMA_WIDTH/HEIGHT macros.

More consistent with the original libmpcodecs code, and the name
"unsharpen" was confusing.

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.

They have been renamed to allow sharing with audio.

The struct is going to be used for storing audio buffer references as
well, and the new name is more generic.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
