this change makes parallel deblocking experiment works with
cb4x4. the inner loop process every 4x4 block.
Change-Id: I86adb3d7b6d67a91ccc12aab29da9bfb8c522cf1
this change adds the following filter tap options:
1. add options to replace 15 tap filter with 9 or 11 tap filter
2. force chroma plane to only use maximum 7 tap filter
above options are disabled by default

The parallel_deblocking experiment is proposed jointly by Intel
and Microsoft. The following changes are implemented in this
experiment:
- deblocking filter order is changed to filter all vertical edges
of the whole frame followed by filtering all horizontal edges
of the whole frame
- filter length decision is made based on the transform block size
on both sides of the edge. block with smaller transform size
determines the final filter length.
- transform blocks on both sides of the edge are checked, only when
both blocks are skipped and they belong to the same prediction
block, filtering of that edge can be skipped.
- 15-tap filter and extended flat area detection are removed.
- special rule for handling 4x4 transform block on the super block
boundary in VP9 is removed.
