More aggresive on avoiding denoising on skin.
May supplement this later by adding condtion onn consec_zeromv.

Different quality levels are used for different regions in
the frame depending on how far they are vertically from the
center. Specifically, three segments are used based on the
mi_row index with respect number to the number of mi_rows in
the frame.

This reverts commit ea48370a500537906d62544ca4ed75301d79e772, reversing
changes made to 15939cb2d76c773950cda40988ede89e111872ea.
The commit was insufficiently tested and causes failures.

This commit adds the logic for segmentation map initialization and
disable temporal update of segmentation map when error-resilient
mode is on. It fixes the enc/dec mistmates (release build) and
assertions(debug) when both aq-mode and error-resilient are on.

Prior to this patch, read_inter_block_mode_info() would
find the nearmv and nearestmv for all modes. Now it does not
search for ZEROMV modes and breaks out early for NEARMV and
NEWMV modes.

The nominal tx_type for a given mode is used as a context
to encode the actual tx_type for intra.

This commit enables encoder to avoid 8x4 and 4x8 partitions for
scaled reference frames when libvpx is configured and built with
--enable-better-hw-compatibility

Move the logic for forcing zero_mode after the
(ref_frame & flag_list) check.
This was causing an memory leak under msan:

Under --enable-better-hw-compabibility, this commit adds the asserts
that no mv clamping is applied for scaled references, so when built
with this configure option, decoder will assert if an input bitstream
triggger mv clamping for scaled reference frames.

This commit adds a new configure option:
--enable-better-hw-compatibility
The purpose of the configure option is to provide information on known
hardware decoder implementation bugs, so encoder implementers may
choose to implement their encoders in a way to avoid triggering these
decoder bugs.
The WebM team were made aware of that a number of hardware decoders
have trouble in handling the combination of scaled frame reference
frame and 8x4 or 4x8 partitions. This commit added asserts to vp9
decoder, so when built with above configure option, the decoder can
assert if an input bitstream triggers such decoder bug.
