Remove AVFilterBufferRefAudioProps.size, and use nb_samples in its place
everywhere.
This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.

Also remove the useless planar parameter, which can be deduced from the
sample format.

This is technically an API and ABI break, but since the audio part of
lavfi is not usable now, this should not be a problem in practice.

This allows compiling the Xvid rate control code without the encoder.

This is similar to what has previously been done in AVFrame to allow
dealing with more than 8 channels.

This would happen at least when lavr is used as a fifo with no
conversion.

This makes only tests actually using avconv depend on it.
The remaining tests already depend on what they need.

Only the probe tests should depend on avprobe and these should
be enabled only if avprobe is configured.

Just like gcc 4.6 and later on ARM, gcc 4.8 on MIPS generates
inefficient code when a known-unaligned location is used as a
memory input operand.  This applies the same fix as has been
previously done to the ARM version of the code.

GCC actually handles unaligned accesses correctly in all cases
except, absurdly, 32-bit loads on mips64.  The remaining asm is
thus not needed, and removing it results in better code.

Also add the public interface libavfilter/buffersink.h.

Unlike other variants, for YUY2 we need to use different prediction:
* on line 0 for luma we should left predict starting from the second pixel
* on line 1 we should left predict first 4 pixels for luma and 2 for chroma
* median prediction employed here is taken directly from HuffYUV
