Changes to allow more use of rectangular partitions at
speeds 1 and 2 for content classed by the first pass as
animation and for blocks near the active image edge.

This has quite a big impact in quality for the animated
test sequence but also hurts encode speed for speed 2.

For other content types the impact on both speed and
quality is small.

Added some plumbing for detection of internal vertical
image edges.

Change speed features / behavior for split mode when there
is an internal active edge (e.g. formatting bars).

Remove some threshold constraints in rd code near the active
edge of the image.

Add some plumbing for left and right active edge detection.

Patch set 5. Limit rd pass through for sub 8x8 to internal active edges.
This takes away any speed penalty for most clips but keeps the enhanced
edge coding for the more critical case of internal image edges

If the pre-selected partition size (from variance partition) is
32x32, also apply nonrd partition search for 32x32 and 16x16 size.

Overall small positive gain in metrics, average ~1%.
Some visual improvement, for lower resolutions.

The decoding process handles detokenization and reconstruction per
transform block sequentially. There is no need to offset the dqcoeff
buffer according to the transform block index. This allows to
reduce the memory spill and improve cache performance.

This commit replaces the vp8_ prefixed subtract function with the
common vpx_subtract_block function. It removes redundant SIMD
optimization codes and unit tests.

inline the code directly in read_mv_component(), the only place where it
was being used; this removes a function call in a hot function
