Sub8x8 blocks will not check the extended region in motion field.
For regular block sizes, limit the extended region to be 3 points,
down from 9 points check.

When either component of a motion vector is above 4096, drop this
motion vector from the motion vector reference frame for later
motion field projection use. The coding performance change is close
to 0 for lowres and midres. This ensures that the motion vector
and reference frame tuple can be efficiently stored within 32 bits.

Use the frame ID that indicates the frame display order to identify
whether two different reference frames exist for inter-coded frames.
If there is only one unique reference valid in the reference buffer,
there is no need to signal reference_mode. Instead, the decoder may
identify such scenario and set reference_mode to SINGLE_REFERENCE.

Check if the global motion undergoes non-translation mode. If that
is the case, do not force a newmv mode into globalmv mode.

This will resolve a mismatch bug of txk_sel.

Added optimized convolve functions for single reference case, so that no
separate post rounding is needed and the result is written to the
destination buffer directly. Duplicate code will be cleaned up later.

Encoder now writes the binary symbol for show_existing_frame to
indicate the value of reset_decoder_state. The default value now
is set as zero regardless. This enables the bitstream match with
the decoder.

With this patch when fwd-kf is enabled, one additional bit is
signaled at the frame header for show_existing_frame, but without
any coding performance impact.

Reduce the reference motion vector search region over the spatial
neighbor blocks for sub8x8 block sizes, in order to reduce the
worst case context model parsing latency.

The speed feature FINAL_PASS_TRELLIS_OPT is meant to disable
optimize_b during the transform search but allow it for the
final encode of blocks. There was a previously existing macro
called DISABLE_TRELLISQ_SEARCH, which does the same thing. This
patch merges the functionality so the macro serves only to enable
the speed feature.

Only the col transforms are needed since the inverse transform
is designed to do row first and then col. So the row
transform can reuse the same configuration as the row transform of
a square transform of the same size.

Small code cleaning and partially resolves issue 1171. I can't confirm
that it's a complete fix because the code asserts further a long

Currently, optimize_txb does not use the new-quant
lookup table when it updates the coefficients. This
fixes the function to avoid a mismatch.

With this patch, new-quant adds 0.28% gains on top of
lv-map-multi on 40 frames of lowres.

INLINE is defined as __forceinline for vs* configs, but is the
normal, compiler-discretion inline for gcc/clang configs. This
makes many functions very large when building for windows targets,
much larger than they are elsewhere.

Use '__inline' as a consistent definition to get consistent function
sizes. Thanks to David Major for the diagnosis.

Removing the drl dependency on the candidate list length appears
to incur more than 0.3% compression performance loss. Hence remove
this option from opt-ref-mv to allow better latency vs compression
performance trade off.
