1. All directional modes except DC/TM/V/H now have built-in filtering
for all pixels with filter taps either (1, 2, 1)/4 or (1, 1)/2.
2. Above edge get automatic extended to double width (bw*2), which
makes a lot of the prediciton mode computation simpler.
3. Same intra prediction function is called with different size
for i4x4_pred and all other larger size.
Overall, the change helped keyframe only coding for both cif size
and std-hd size test sets by .5% consistently on all encodings.
For normal coding with single/auto key frame, the change now also
is consistently net positive for all encodings. The overall gains
is about .15% on std-hd set.

Fix incorrect 32x64, 16x32 subpel variance
Incorrect strides caused use of uninitialized stack data.

Use foreach_transformed_block with tokenize_b
Updates the tokenizer to use the common block walker used by the
detokenizer, to support non-4:2:0 and more than 3 planes.

Fix mi_row argument to update_stats().
This doesn't change output, because the argument isn't actually used
ATM. However, we should fix it for consistency.

Use recursive function in resetting txfm_size for skip-blocks.
This is shorter than fully writing out all cases (52 vs. 84 LOC), and
