2ec112f71c vf_pad: fix x, y option expression evaluation 
Calculation of x an y based on width and height did not work when
width == 0 or height == 0.  "0" substitutes the input width and
height, but did so too late for x, y expression evaluation.

3735b5c616 Revert "lavfi: always check av_expr_parse_and_eval() return value" 
This reverts commit 63be97ec40.

All those calls were unchecked on purpose, as explained in the comments
in the code.

737eb5976f Merge libavcore into libavutil 
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

e3331706fc Fix design of the pad filter. 
Previously the pad filter just drawed borders in the surrounding of the input
without checking if this area was allocated or writeable. Now we check and
allocate a new buffer if the input is unsuitable.

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.

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.
