This patch continued the work done in "Rewrite loop_filter_info_n
struct"(commit:00dbd369c70270428d56da6d15ea5486fc821c52) to further
improve loopfilter function.
1. Instead of storing pointers to thresholds, store loopfilter
levels within 64x64 SB;
2. Since loopfilter levels are already calculated in setup_mask,
we don't need call build_lfi to look up them again. Just save
loopfilter levels in setup_mask.
3. Reorganized and simplified filter_block_plane().
Tests showed a ~0.8% decoder speedup.

SVC multiple layer per frame encoding is invoked with vpx_svc_init and
vpx_svc_encode. These interfaces are designed to be invoked from ffmpeg.
Additional improvements:
- make dummy frame handling a bit more explicit
- fixed bug with single layer encodes
- track individual frame sizes and psnrs instead of averages
- parameterized quantizer, 16th scalefactors, more logging,
- enabled single layer encodes to generate baseline
- include new mode for 3 layer I frame with 5 total layers

Removing special case handling from vp9_tree_probs_from_distribution(),
tree_merge_probs(), and vp9_tokens_from_tree_offset() functions. Replacing
inter_mode_offset() function with macro INTER_OFFSET which is used now for
vp9_inter_mode_tree definition.

We only update partition_probs for inter frames but they are constant
for key frames. It is not necessary to have constants inside frame
context and copy them every time. This change reduces FRAME_CONTEXT size
by at least 48 bytes.

We don't have to calculate 'new' probability in convert_distribution()
because it is enough to calculate only 'new' counters which could be used
to calculate probability if necessary. That's why removing a lot of unused
temporary probability arrays and reducing number of get_binary_prob()
calls.

This CL contains two AVX2 optimized loop filter functions,
mb_lpf_horizontal_edge_w_avx2_8 and mb_lpf_horizontal_edge_w_avx2_16.

"<< SUBPEL_BITS" needs to be added in the calculation. Call
set_scaled_offsets() to calculate x_offset_q4 and y_offset_q4.

It is enough to check just block type: intra or inter. Intra block implies
intra prediction mode, and inter block implies inter mode.

replaces use of cur_tile_mi_(row|col)_(start|end) by VP9_COMMON, making
it less stateful and more reusable for parallel tile decoding

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.

update_partition_context / partition_plane_context: this will allow for
separate storage to be used in tile decoding
