Further segment feature extensions. This quite large check in includes the following: Merge in some code from Ronald (mbgraph.c) that scans a Gf/arf group. This is used as a basis for a simple segmentation for the normal frames in a gf/arf group. This code also uses satd functions from Yaowu. Adds functionality for coding the latest possible position of an EOB for blocks in the segment. (Currently 0-15 only, hence just for 4x4 dct). Where the EOB position is 0 this acts like "skip" and the normal coding of skip at the per mb level is disabled. Added functions (seg_common.c) for setting and reading segment feature elements. These may want to be optimized away at some point but while the mecahnism is in a state of flux they provide a single location for making changes and keep things a bit cleaner. This is still proof of concept code. Currently the tested feature set:- Quantizer, Loop Filter level, Reference frame, Prediction Mode, EOB end stop. TBD:- Add functions for setting and reading the feature data with range and validity checking. Handling of signed and unsigned feature data. At the moment all is assumed to be signed and a sign bit is coded but many cannot be negative. Correct handling of EOB feature with intra coded blocks. Testing/trapping of legal/illegal ref frame and mode combinations. Transform size switch plus merge and test with 8c8 DCT work Merge and test with Sumans Segmenation coding optimizations Change-Id: Iee12e83661c7abbd1e0ce6810915eb4ec35e2d8e

/*
Reference frame prediction: Extended prediction and coding of reference frame where a subset of options are flagged as available at the segment level. Updated copyright notices. Switch to SAD in mbgraph code as SATD problematic for the foreground and background separation as it can ignore large DC shifts. Change-Id: I661dbbb2f94f3ec0f96bb928c1655e5e415a7de1

Further QIndex realted Fixes: Added code to support 256 index steps instead of 128 but disabled for now. Replace hard wired table vp8cx_base_skip_false_prob[128] Observed Qindex problem with setting minimum loop filter value. (Experiment code using real Q in place but for now just returning 0. This has a big beneficial effect on some clips, particularly waterfall which shows 5% ssim gain) Change-Id: I2f7117de8adc1797164c106aa13effc900a1467e
