Refactoring: split prediction+extension for each plane, so we can
handle luma/chroma supertx pred in different ways.
Compatibility fix: fix conflicts with cb4x4 and chroma_sub8x8, now
for chroma sub8x8 supertx, only the top-left(basic cb4x4) or the
the bottom-right(cb4x4 + chroma_sub8x8) predictor will be used
without any blending within a 8x8 unit.

Check the availability of the reference frames at the frame level at
both encoder and decoder, and if a reference frame is not available
for a specific video frame, remove the signaling of such reference
frame info at the block level.

This patch adds the consideration of the bit saving inside the RD
optimization loop.

This unifies the codepath for high-bitdepth transforms and deletes
all calls to the old deprecated versions. This required reworking
the way 1d configurations are combined in order to support rectangular
transforms.

There is one remaining codepath that calls the deprecated 4x4 hbd
transform from encoder/encodemb.c. I need to take a closer look
at what is happening there and will leave that for a followup
since this change has already gotten so large.

When frame_superres is on, loop-restoration should work
on the size of the upscaled frame and not on the internal
width and height in the common structure. This patch
makes the necessary changes on the encoder and decoder
side to enable that.

This reverts commit 846d67dd.

Writing the scale every frame was not the right decision. The correct
thing to do will be also writing the superres scale when the size is
set using a previous frame.

reset_skip_context() was always clearing the entropy contexts for
all three color planes, using a block size that corresponded with
the luma plane.

However, when chroma_2x2 is disabled, then for sub-8x8 luma block
sizes, the corresponding chroma block size is always 4x4, and the
skip flag only affects the chroma blocks corresponding to the
upper-left luma block.

This patch makes reset_skip_context() reset the contexts that
actually correspond to the chroma blocks that are skipped (if any).
It also moves reset_skip_context() to av1_reset_skip_context() in
blockd.c, because blockd.h gets included before onyx_int.h, which
declares the required is_chroma_reference() function.
reset_skip_context() was too large and used in too many places to
be a reasonable candidate for inlining, anyway.

Encode a block line by line, horizontally or vertically. In the vertical
mode, each row is predicted by the reconsturcted row above;
in the horizontal mode, each column is predicted by the reconstructed
column to the left.

The DPCM modes are enabled automatically for blocks with horizontal or
vertical prediction mode, and 1D transform types (ext-tx).

The superres scale was accidentally only sent if the current frame was
a key frame or if the current resolution was not used by any of the
reference frames. This patch separates the superres scale from the
current resolution to simplify its coding and makes sure that it is
written for every frame.
