Fix the issue that causes array bound excess in getting partition
context.

The encoder reconstruction is now correct. Decoder to follow shortly.

This commit enables bit-stream writing and reading for recursive
partition down to block 8x8.

Change-Id: I163cd48d191cc94ead49cbb7fc91374f6bf204e2

Unify the various vp9_optimize_sb functions into one that handles all
transform sizes.

The decode_mb only carries I8X8_PRED decoding, which will be covered
by the regular MB intra modes when SB8X8 is on. To be removed later.

Work-in-progress, not yet ready for review. TODO items:
- bitstream writing (encoder) and reading (decoder)
- decoder reconstruction

Change-Id: I5afb7284e7e0480847b47cd0097cb469433c9081

Moving common code from encoder and decoder to vp9_get_qindex function.
Also moving quant-related constants from vp9_onyxc_int.h to
vp9_quant_common.h.

(cherry picked from commit 296421d8)
reverts: dbd050c5 vpxdec: correct VP[89] fourccs

Moving common code from encoder and decoder to vp9_update_frame_size.

Change-Id: I6ca758b7d05ffd52821bd3f7ad68089da11e4165

Separate the decoding process of 4x4 block based coding (both intra
and inter) from decode_mb and move it into decode_atom_. This allows
to further move the rest per 16x16 block decoding of decode_mb into
decode_sb, and hence eventually deprecating decode_mb when SB8X8 is
enabled.
