Aneesh DograandRonald S. Bultje 4fbccfab23 sunrast: Add support for gray8 decoding.

Ronald S. Bultje dae2ce361a swscale: enforce a minimum filtersize. 
At very small dimensions, this calculation could lead to zero-sized
filters, which leads to uninitialized output, zero-sized allocations,
loop overflows in SIMD that uses do{..}while(i++<filtersize); instead
of for(i=0;i<filtersize;i++){..} and several other similar failures.
Therefore, require a minimum filtersize of 1.

Ronald S. Bultje 45b7bd7c53 h264: disallow constrained intra prediction modes for luma. 
Conversion of the luma intra prediction mode to one of the constrained
("alzheimer") ones can happen by crafting special bitstreams, causing
a crash because we'll call a NULL function pointer for 16x16 block intra
prediction, since constrained intra prediction functions are only
implemented for chroma (8x8 blocks).
