Adding RefBuffer to simplify reference buffer management. The struct has a
pointer to image data and scale factors relative to the current frame.

Moving back to scale_factors struct. We don't need anymore x_offset_q4 and
y_offset_q4 because both values are calculated locally inside vp9_scale_mv
function.

- Disable mode info update in case where current frame is coded
as "show existing frame".
- Should fix issue 676.

The old code would start in a mixed state, where all the reference
frames were pointing to frame buffer 0, but the reference counts
were 0. This is why we needed special code for the first frame.

Reversing bit order of partition_context_lookup, and modifying accordingly
update_partition_context() and partition_plane_context().

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.

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

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

The ref's scale_factors are set at frame level, and then copied for
each partition block. Since the struct members are mostly constant,
this patch separated the constant and non-constant members, and
reduced struct copying. This gave 0.5% ~ 1.4% decoder speed gain.

We used set_partition_seg_context() only before calls to:
1. update_partition_context()
2. partition_plane_context()
Moving these functions from vp9_blockd.h to vp9_onyxc_int.h and
inlining set_partition_seg_context into them. After that it is not
necessary to have {above, left}_seg_context fields in MACROBLOCKD struture,
so removing them also.

Renames for consistency with other constants:
NUM_FRAME_TYPES -> FRAME_TYPES
NUM_PARTITION_CONTEXTS -> PARTITION_CONTEXTS
Change-Id: I3db30acb2868eb0a424237c831087b2e264ec47f
Updated the encoder to handle frames that are coded
intra-only. Intra-only frames must be non-showable,
that is, the "show frame" flag must be set to 0 in
the frame header.
Tested by forcing the ARF frames to be coded intra-
only.
Note: The rate control code will need to be modified
to account for intra-only frames better than they
are currently handled.

mode_info_context was stored as a grid of MODE_INFO structs.
The grid now constists of pointers to MODE_INFO structs. The
MODE_INFO structs are now stored as a stream (decoder only),
eliminating unnecessary copies and is a little more cache
friendly.

mode_info_context was stored as a grid of MODE_INFO structs.
The grid now constists of a pointer to a MODE_INFO struct and
a "in the image" flag. The MODE_INFO structs are now stored
as a stream, eliminating unnecessary copies and is a little
more cache friendly.
For the test clips used, the decoder performance improved
by ~4.3% (1080p) and ~9.7% (720p).
Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p)
and 5.9% (720p).
