In subpel_avg_variance functions, code similar to the following

punpkldq m2, [addr]

actually reads 8 bytes. For functions that are supposed to work on
buffers only have less 8 bytes a line, this caused valgrind error
of reading uninitialized memory.

Adding temporary "typedef BLOCK_SIZE BLOCK_SIZE_TYPE" which will go away
after encoder's patch.

issue in the SSSE3 implementation of 32x32 quantization.

- s|source -> src
- dest -> dst
- use verbose names in extend_plane dropping the redundant comments

+ light cosmetics:
- join a few lines / assignments
- drop some unnecessary comments & includes

I've already renamed d27_predictor to d207_predictor but forgot about the
corresponding constant.

Previous change c4048dbd limits the mv search range assuming max block
size of 64x64, this commit change the search range using actual block
size instead.

We could avoid calling clamp_mv2 because it has been already called
inside vp9_find_best_ref_mvs function.
