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.

Removing references to plane_block_width and plane_block_height (we are
going to delete the latter ones).

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

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.

Fix of https://code.google.com/p/webm/issues/detail?id=608. We could have
used invalid display size equal to the previous frame size (not to the
current frame size).

Making code more compact, adding consts, removing redundant arguments,
adding do/while(0) for macros.

To the source buffer to be encoded as an alt ref frame. This is to fix
the problem of using uninitialized memory in encoder.

(In response to Issue 604:
https://code.google.com/p/webm/issues/detail?id=604)
There were bugs in the convolution code for two cases:
1. Where the filter table was assumed to be aligned to a
256 byte boundary. The offset of the pixel in the
source buffer was computed incorrectly.
2. Where no such alignment assumption was made. An
incorrect address for the filter table base was used.
To fix both problems, I now assume that the filter table is
256-byte aligned and modify the pixel offset calculation to
match.
A later patch should remove the restriction that the filter
table is aligned to a 256-byte boundary.
There was also a bug in the ConvolveTest unit test
(convolve_test.cc).
(Bug & initial fix suggestion submitted by Tero Rintaluoma
and Sami Pietilä).
