Remove AVFilterBufferRefAudioProps.size, and use nb_samples in
avfilter_get_audio_buffer() and avfilter_default_get_audio_buffer() in
place of size.
This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.
The new flags parameter allows to specify if the video ref to add
should overwrite the cache, if the flag is not set vsrc_buffer will
complain and abort; otherwise it will clean the already cached video
ref before to overwrite it, thus avoiding a leak.
Since this is only a compilation check (the actual function used is
selected at runtime) and HAVE_SSE indicates that we can also compile
SSE2 code, this is correct.

Require the presence of opencv/cxcore.h in place of opencv/cxtypes.h,
which has been removed. Fix compilation with libopencv > 2.1.0.
Fix trac issue #221.
The new function is a wrapper around
av_vsrc_buffer_add_video_buffer_ref(), and allows to simplify the act
of pushing AVFrame data to the source buffer.
Rename av_vsrc_buffer_add_frame to
av_vsrc_buffer_add_video_buffer_ref(), and change its inteface to make
it accept in input an AVFilterBufferRef rather than an AVFrame.
This way the interface can be used without requiring the
inclusion/installation of libavcodec headers.

vf_drawtext.c:NNN: warning: missing braces around initializer

Improve consistency with libavcodec.
This breaks libavfilter API/ABI.
The non-sequential 2.1.0 -> 2.4.0 bump is due to the mess previously
done with the lavfi minor number.
The sample aspect ratio is a per-frame property, so it makes sense to
define it in AVFrame rather than in the codec/stream context.
Simplify application-level sample aspect ratio information extraction,
and allow further simplifications.
This is similar to what was done with pkt_pts. This simplifies the
operation of extracting the pos information from the AVPacket, and
allows further simplifications.

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.
