Mans Rullgard cbc7d60afa arm: dsputil: fix overreads in put/avg_pixels functions 
The vertically interpolating variants of these functions read
ahead one line to optimise the loop.  On the last line processed,
this might be outside the buffer.  Fix these invalid reads by
processing the last line outside the loop.

Kostya Shishkov 464e9ab011 lagarith: add YUY2 decoding support 
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

Paul B MaholandLuca Barbato 37f4a976b3 zerocodec: check if the previous frame is missing 
ZeroCodec relies on the keyframe flag being set in the container, and
prev is the previously decoded frame. A keyframe flags incorrectly set
will lead to this condition.

Mans Rullgard 58b2e0f0f2 vqavideo: return error if image size is not a multiple of block size 
The decoder assumes in various places that the image size
is a multiple of the block size, and there is no obvious
way to support odd sizes.  Bailing out early if the header
specifies a bad size avoids various errors later on.

Fixes CVE-2012-0947.
