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.

libavcodec/utils.c:274: warning: passing argument 3 of ‘av_samples_fill_arrays’ discards qualifiers from pointer target type
./libavutil/samplefmt.h:151: note: expected ‘uint8_t *’ but argument is of type ‘const uint8_t *’

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
