This setup is now handled by vp9_build_intra_predictors()
when left_available and/or up_available is zero.

This allows removing a large number of transform size specific functions,
as well as supporting 444/alpha by routing all code through the
subsampling-aware path.

The number of reference buffers is extended to 8 and
a reference sign-bias added for the LAST_FRAME.
Whilst the number of reference buffers used by an
individual frame remains unchanged at 3, these may
now be selected from 8 possible buffers.

Work-in-progress, not yet ready for review. TODO items:
- bitstream writing (encoder) and reading (decoder)
- decoder reconstruction
Change-Id: I5afb7284e7e0480847b47cd0097cb469433c9081
Changing the order of probabilities inside mb_segment_tree_probs in order
to use treed_read/treed_write function instead of custom code.
Change-Id: I843487d5057913b9358db73da270893eefecc6c8
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.
Change-Id: I70c5bfbaa1c8bf00fde0bfc459d077f88b6d46c8
Separate the functionality of I4X4_PRED from decode_mb. Use
decode_atom_intra instead, to enable recursive partition of superblock
down to 8x8.

Also fixed two minor subtle boundary conditions in intra prediction
code, and replaced memcpy/memset with vpx_ prefixed version.

The commmit changed to use same intra prediction function for all
block sizes.
Some details on the changes:
1. All directional modes except DC/TM/V/H now have built-in filtering
for all pixels with filter taps either (1, 2, 1)/4 or (1, 1)/2.
2. Above edge get automatic extended to double width (bw*2), which
makes a lot of the prediciton mode computation simpler.
3. Same intra prediction function is called with different size
for i4x4_pred and all other larger size.
Overall, the change helped keyframe only coding for both cif size
and std-hd size test sets by .5% consistently on all encodings.
For normal coding with single/auto key frame, the change now also
is consistently net positive for all encodings. The overall gains
is about .15% on std-hd set.

Output changes slightly because of a minor bug in (at least) the sb32x16
block2above tx16x16 tables that previously existed in vp9_blockd.c.
