Add drawutils.h and drawutils.c, and use them in the pad filter.
The new functions are going to be shared by other filters.

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.

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.

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.

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.

AVFilterBufferRef.pic -> AVFilterBufferRef.buffer
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.

in favor of the newly added corresponding functions
av_parse_video_size() and av_parse_video_rate() defined in
libavcore/parseutils.h.
This change also adds a linking-time dependency of libavcodec and of
libavfilter on libavcore.

the pad filter.
