- Const correctness
- Refactoring
- Make variables local when possible
etc
- Remove -Wcast-qual to allow explicitly casting away const.

In super_block_uvrd(),if is_cost_valid == 0, all return parameters,
i.e. rate, distortion, skippable, and sse, are reset.
So, should not call txfm_rd_in_plane() if is_cost_valid == 0.
Also, the bug causes av1_xform_quant() to see invalid diff signal
since av1_subtract_plane() is not called in super_block_uvrd().

Given the largest transform size is 32x32, this commmit changes size
estiiation based on the size rounding up to 32 multiples to avoid
insufficient buffer allocations.

This commit increases the minimum size for allocated buffer for
compressed data. The old size underestimated the size needed for
small images with width or height less than 64 pixels.

This improves the encoding speed. For bus at CIF 1000 kbps, the
encoding time (speed 0) goes down from 248000 ms to 231000 ms,
i.e., 7% speed-up.

This commit resets the transform size to be the maximum possible
value. It avoids out-of-boundary writing when the ActiveMap is
turned on.

This avoids an encoding segmentation fault in speed 5, due to the
use of uninitialized dummy inter prediction filter buffer in the
dynamic motion vector referencing scheme.

It was used by skin detection and the denoiser both of which were
removed. The similar av1_write_yuv_rec_frame() remains for your frame
dumping needs.

The difference between src and dst will be signed, the error will be
unsigned. The change quiets -fsanitize=integer:
unsigned integer overflow: 4294967295 * 4294967295

This commit makes the decoder to construct the reference motion
vector candidate list only for the selected reference frames. This
improves the decoder speed. For the test clip pedestrian_area at
1080p, coded at 3000 kbps, the decoding speed goes up from 58.4 fps
to 72 fps.

Adds ext-tx transforms to enums.h and adds implementations
for idtx and flip functions for FLIPADST. Note that 32x32 transforms
are now included for ext-tx only.

The ans writer is currently allocated in the encoder context to prevent
per frame reallocation of the reversal buffer.

In the experiment of EXT_REFS, MAX_REF_FRAMES has increased from 4
to 7, as 3 more reference frames have been added.
Change-Id: I3fec2c2078f925afe518b454e3f71afbd7379d06
For the experiment of EXT_REFS, add following functionalities to
support new references, in particular, to support the bi-directional
prediction:
(1) Add support to handle reference frame update; and
(2) And support to handle show_existing_frame == 1.

This removes the unused spatial scalability, temporal layers, and svc
parameters from the aom API. There is no code implementing these APIs,
and if it they are needed in the future, just resurrect them from this
commit. The skin_detection code is unused and won't be used.

Handle the sub8x8 chroma component at the unit of 2x2/4x2/2x4 level
and use the motion vector inherited from the luma component. This
improves the coding performance:
lowres 0.4%
midres 0.25%
hdres 0.15%
Change-Id: I34dff4218cfa3e5d55e7ed0341f36f4719389f7e
Following supports are added in the decoder:
(1) Decoder support to show_existing_frame == 1;
(2) Decoder support to avoid the referring to non-reference frames;
(3) Decoder support to handle the case when cm->prev_frame gets retired
in the reference buffer.

This commit makes the dynamic motion vector referencing system
support multiple backward reference frames, hence making the
two experiments work properly.
