Restructured the storing of loopfilter information. Deleted
loop_filter_info struct and reduced copying happened in every
superblock.

Tests showed a 0.5% ~ 0.8% decoder speed gain.

VP9_COMMON is the right place to segmentatation struct because it has
global segmentation parameters, not something specific to macroblock
processing.

Loop filter configuration doesn't belong to macroblock, so moving it from
MACROBLOCKD to VP9_COMMON. Also moving the declaration of loopfilter struct
from vp9_blockd.h to vp9_loopfilter.h.

Currently the only threaded option for vp9 decode. Enabled when the
decoder config thread count is > 1.

Renamed:
  MAX_MB_SEGMENTS to MAX_SEGMENTS
  MB_SEG_TREE_PROBS to SEG_TREE_PROBS

The minimum unit for segmentation in the segment map
is now 8x8 so it is misleading to use MB_ as macro-block
traditionally refers to a 16x16 region.

Change-Id: I44155253e8d6771e5e039d663be5f21cc9d0355d

Adding loopfilter struct with fields from MACROBLOCKD and VP9Common.
Eventually it will be moved to vp9_loopfilter.h for better code structure.

Change-Id: Iaf5fb71c33719cdfa1b991f671caf071be9ea035

Cosmetic code changes, renaming 'flat' local var to 'mask', removing
unused field 'blim' from loopfilter_info_n and loop_filter_info structs.

Change-Id: I51e6ccf727fe361ad9a08e29e1201aa7abd4987f

also remove prototype_loopfilter{,_block} defines from vp9_loopfilter.h

Change-Id: I8c8f1f421f7fc84d2efb80349cd725de3c9bf6bd

Adding segmentation struct to vp9_seg_common.h. Struct members are from
macroblockd and VP9Common structs. Moving segmentation related constants
and enums to vp9_seg_common.h.

Using MAX_LOOP_FILTER constant instead of number 63.

Change-Id: If91e0c198331b3041e7cd0707a5948479e9209d8

Modified to work with 8x8 blocks of memory.  Will revisit
later for further optimizations.  For the HD clip used, the
decoder improved my 20%.

We don't have two loopfilter types anymore.

Also some further simplification following removal
of top node code.

There is an issue in regards to the shared file vp8cx.h
in regard to the roi_map as this interface assumes that
there are only 4 segments. I have left the value here as
4 for now meaning that the roi_map interface is broken
for VP9.

Note that this change would have been easier if I hadn't
had to search for hard wire instances of the number 4
and <= 3.

Using filter_level/16 instead.

Adds a per-frame, strength adjustable, in loop deringing filter. Uses
the existing vp9_post_proc_down_and_across 5 tap thresholded blur
code, with a brute force search for the threshold.

Results almost strictly positive on the YT HD set, either having no
effect or helping PSNR in the range of 1-3% (overall average 0.8%).
Results more mixed for the CIF set, (-0.5 min, 1.4 max, 0.1 avg).
This has an almost strictly negative impact to SSIM, so examining a
different filter or a more balanced search heuristic is in order.

Other test set results pending.

Updated the rtcd_defs and used the sse2 uv version
of the loopfilter.  The performance improved by ~8%
for the test clip used.

This commit did a couple of minor cleanup/refactoring to prepare for
futher loop filter experiments. It merged y_only version of loop filter
function into the regular one, which makes sure that same logic is used
for functions for picking level and for actual loop filtering.

Change-Id: Id10c94dccd45f58e5310bacfdf6ee63cbb60b86f

For coefficients, use int16_t (instead of short); for pixel values in
16-bit intermediates, use uint16_t (instead of unsigned short); for all
others, use uint8_t (instead of unsigned char).

Most of these were picked up by jenkins in the commit that changed
the vp8 namespace to vp9 in common/.
