The example in bug 712 is a bitstream that signals a global motion
type of ROTZOOM, but its second frame has shear parameters that fail
the is_affine_shear_allowed check at warped_motion.c:754. This is
quite possible (and it's not obvious how to change the bitstream
format so that you can't signal something like this).

This patch replaces the failing assertion with a proper "no you
can't!" error.

Patch https://aomedia-review.googlesource.com/c/aom/+/20200, merged as
32d150b6, converted several functions in pickrst.c to take a
"use_highbitdepth" flag as well as (or instead of) the actual bit
depth.

Unfortunately, I missed a call site and the code can end up passing
the number 8 as the flag for use_highbitdepth (and, since 8 != 0, this
ends up using the high bit depth patch).

BUG=aomedia:714

Change-Id: Ie4dbad92f57ea1bacc4d99aad15454d9e5b6ff47

The code was incorrectly using "bit_depth == 8" as a test for whether
to use the highbd path or not.

Rather than encoding the loop restoration coefficients at the start of
the frame header, this patch moves them to occur just after certain
top-level superblocks.

You might hope that we could just encode coefficients on top-level
superblocks where the top-left corner of the superblock was also the
top-left corner of the loop restoration tile. Unfortunately, this
can't work with the superres experiment, where the loop restoration
tiles don't necessarily line up with the superblocks. Indeed, in
general there can be multiple different loop restoration coefficients
that apply in a given top-level superblock. This patch defines a
function, av1_loop_restoration_corners_in_sb, which yields the
rectangle [rrow0, rrow1) x [rcol0, rcol1) of loop restoration tiles
whose top left corners lie in this top-level superblock.

The total file size should be unchanged by this patch: the bits have
just been moved from the frame header and spread out among the rest of
the frame.

Derive the rate cost from the probability model sets effectively
in use.

Change-Id: Ief1851a32ea7a3a52e82f52050cdc3dae6c72287

Lots of small bug fixes, mainly around the transform size coding:

* The loop filter was accidentally using the non-subsampled
  block size for the V plane, due to comparing a plane index
  (0, 1, or 2) against PLANE_TYPE_UV (== 1)

* We allowed an initial update of the transform partition probabilities
  even on frames where we know they will never be used
  (because tx_mode != TX_MODE_SELECT).
  Further, these probabilities would not be reverted at the end
  of the frame, leading to the probability delta persisting across frames.

  Change this to behave more like the non-var-tx transform size coding,
  where probability deltas are only coded for frames with
  tx_mode == TX_MODE_SELECT, and the deltas only apply for one frame.

* Fix decoder for the case where the video as a whole isn't lossless,
  and we have tx_mode == TX_MODE_SELECT, but the current segment
  *is* lossless.
  Note that the encoder already does the right thing in this case.

* Don't allow the transform splitting to recurse "below" 4x4.
  This is really just a refactor, but means we can increase the
  maximum depth when subdividing rectangular transforms if we
  want to, whereas the previous code would have needed special cases
  for 4x8 and 8x4 transforms.

* Finally, when we hit the maximum splitting depth, don't update
  the counts as if we had coded a 'no split' symbol.

This is a baby-step towards encoding the coefficients at the start of
superblocks at the top-left of loop restoration tiles. Note that this
patch causes us to reset "wiener_info" and "sgrproj_info" at each tile
boundary, which will cause a performance drop.

This is necessary because, in order for tiles to be processed in
parallel, we cannot delta-encode coefficients across tile boundaries
if the coefficients are signalled within tiles. We could probably do
better than the current patch by, say, delta-encoding against previous
frames.

This patch also fixes up the costing in pickrst.c to match

This patch eliminates the is_inside() checking for each neighouring
block in scan_row_mbmi() and scan_col_mbmi(). Instead, in
setup_ref_mv_list(), find maximum above row_offset and left col_offset
for current block, and use them to decide which above rows and left
columns to search on. This patch doesn't change bitstream. No
noticeable speedup is seen.
