Pull sb8x8 out of experimental list. verified via borg run tests.
Fixed unit test failures.

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

Change-Id: I59cec0ab95f8be69ce885fd20727510e4deef8a0

Moving code from vp9_pack_bitstream to new function encode_segmentation.

All members can be referenced from their per-plane counterparts, and
removes assumptions about 24 blocks per macroblock.

Change-Id: I7ff2fa72d22c29163eb558981c8193765a8113d9

Access these members from MACROBLOCKD instead.

Change-Id: I593fb0715e74cd84b48facd1c9b18c3ae1185d4b

Continue moving framebuffers to per-plane data.

Change-Id: I237e5a998b364c4ec20316e7249206c0bff8631a

Removes the redundant dst pointers from vp9_build_inter_predictors_sb{y,uv}
and the remaining mb specific functions.

Change-Id: I7b6bf439d9394b85ea79b4fe61a3ffc1025720da

First in a series of commits moving the framebuffers pointers to
per-plane data, so that they can be indexed numerically rather than
by name.

Change-Id: I6e0d60fd4d51e6375c384eb7321776564df21775

Use in-place buffers (dst of MACROBLOCKD) for  macroblock prediction.
This makes the macroblock buffer handling consistent with those of
superblock. Remove predictor buffer MACROBLOCKD.

Increase the motion search range by 4x. Change MV_CLASS tree of the
entropy coding to allow two additional mv classes to cover the
extended motion vector limit. The codec determines the effective
motion search range conditioned on the actual frame dimension.

It provides coding gains:

stdhd 0.39%
yt    0.56%
hd    0.47%

Major coding performance gains are packed in several sequences with
intense motion activities, e.g., ped_1080p gains 7% at high bit-rates,
and on average 3%.

TODO: Need to further tune the rate control and motion search units.

Change-Id: Ib842540a6796fbee5a797809433ef6a477c6d78d

Removing redundant 'extern' keyword, better formatting, code
simplification.

Change-Id: I132fea14f08c706ee9ea147d19464d03f833f25b

This patch makes the encoder's use of ref_frame_map and active_ref_idx
consistent with the decoder. ref_frame_map[] maps a reference buffer
index to its actual location in the yv12_fb array, since many
references may share an underlying buffer. active_ref_idx[] mirrors
cpi->{lst,gld,alt}_fb_idx, holding the active references in each
slot.

This also fixes a bug in setup_buffer_inter() where the incorrect
reference was used to populate the scaling factors.

Change-Id: Id3728f6d77cffcd27c248903bf51f9c3e594287e

This patch allows coding frames using references of different
resolution, in ZEROMV mode. For compound prediction, either
reference may be scaled.

To test, I use the resize_test and enable WRITE_RECON_BUFFER
in vp9_onyxd_if.c. It's also useful to apply this patch to
test/i420_video_source.h:

  --- a/test/i420_video_source.h
  +++ b/test/i420_video_source.h
  @@ -93,6 +93,7 @@ class I420VideoSource : public VideoSource {

     virtual void FillFrame() {
       // Read a frame from input_file.
  +    if (frame_ != 3)
       if (fread(img_->img_data, raw_sz_, 1, input_file_) == 0) {
         limit_ = frame_;
       }

This forces the frame that the resolution changes on to be coded
with no motion, only scaling, and improves the quality of the
result.

Change-Id: I1ee75d19a437ff801192f767fd02a36bcbd1d496

Ensure that all inter prediction goes through a common code path
that takes scaling into account. Removes a bunch of duplicate
1st/2nd predictor code. Also introduces a 16x8 mode for 8x8
MVs, similar to the 8x4 trick we were doing before. This has an
unexpected effect with EIGHTTAP_SMOOTH, so it's disabled in that
case for now.

Change-Id: Ia053e823a8bc616a988a0af30452e1e75a739cba

Remove lst_fb_idx, gld_fb_idx, alt_fb_idx, refresh_last_frame,
refresh_golden_frame, refresh_alt_ref_frame from common. Gold/Alt are
encode side conventions. From the decoder's perspective, we want to be
dealing with numbered references.

Updates to active_ref 2 signal mode context switches, vestigial from
refresh_alt_ref_frame. This needs some clean up to make sense with
increased numbers of reference frames, as well as reimplementing the
swapping of alt/golden which was previously done using the
buffer-to-buffer copy mechanism removed in an earlier commit.

Change-Id: I7334445158b7666f9295d2a2dd22aa03f4485f58

This patch removes the old pred-filter experiment and replaces it
with one that is implemented using the switchable filter framework.

If the pred-filter experiment is enabled, three interopolation
filters are tested during mode selection; the standard 8-tap
interpolation filter, a sharp 8-tap filter and a (new) 8-tap
smoothing filter.

The 6-tap filter code has been preserved for now and if the
enable-6tap experiment is enabled (in addition to the pred-filter
experiment) the original 6-tap filter replaces the new 8-tap smooth
filter in the switchable mode.

The new experiment applies the prediction filter in cases of a
fractional-pel motion vector. Future patches will apply the filter
where the mv is pel-aligned and also to intra predicted blocks.

there are still a couple type of warning left, which are related to
double constants assigned to float type. As those would be addressed
by the conversion of transforms into integer version. This commit
has left those un-dealt with.

the vp8 namespace to vp9 in common/.

Change-Id: I5cbd56ffc753b92ef805133cda6acc1713a13878

For non-static functions, change the prefix to vp9_. For static functions,
remove the prefix. Also fix some comments, remove unused code or unused
function prototypes.
