The post relocation destination of some non-simd sources
that require specific simd flavors was incorrect. The
relocated sources touch internal APIs, and the incorrect
destination was an unguarded area where sources are added
unconditionally to targets with the assumption that all
APIs are accessible.

Sources moved to section guarded by BUILD_SHARED_LIBS, which
acts as the border between public APIs always available for
testing and those that require a static lib that exposes
private symbols.

A failing 'assert' aborts the execution of the test suite,
instead of simply failing the erroneous test, and continuing with other tests.

Added a sample selection process in warped motion.
1. Gather more samples including multiple rows on the top, multiple
columns on the left, and the upper-right block.
2. Sort samples by the MV difference between the neighbour's MV and
the current block's MV. Trim the samples with considerably large MV
difference.

Borg test result:
             avg_psnr ovr_psnr ssim
cam_lowres:  -0.241   -0.243  -0.376
lowres:      -0.104   -0.110  -0.179

The changes are wrapped in WARPED_MOTION_SORT_SAMPLES macro.

The memset to 0 wasn't required because the temporary variable is only
written to, before being read in the next function call.

Always let the encoder decide if "allow_screen_content_tools" should be set.

-The screen content detector(is_screen_content()) works fairly well.

-Keeping the config control may lead to mismatches. For example, user
may encode the 1st frame with the flag on, then turn the flag off for
the 2nd frame via config control. On the decoder side, the flag is on
for both frames, because the flag is only transmitted in the header of
all-intra frame, i.e. the 1st frame in this example.

Added a 1-bit flag 'large_scale_tile'. If it is 0 that is the default value,
use normal tile coding in TILE_GROUPS. If it is 1, use large-scale tile
coding in EXT_TILE.

At large_scale_tile=1 case, if single-tile-decoding is required, then the
loopfilter is disabled.

Related API and unit tests were modified.

Before this, this function was copied-and-edited from
av1_build_inter_predictors_sby() and av1_build_inter_predictors_sbuv().
Also, some places used sb() one directly (like rdopt.c), while others used
sby() and sbuv() separately (like encodeframe.c --> encode_superblock()).

This was prone to errors, if someone mistakenly modified only one/two of
the 3 functions.

Now, we just reuse sby() and sbuv() functions in sb().

Verified that there's no change in output.

The goal is:
1) to provide a tool allowing to diagnose
and fix mismatches between LBD/HBD coding paths.

2) once all mismatches are fixed, this test
should be enabled so new ones can't be introduced.

Due to rounding the variance can become negative.
Similar behaviour has been fixed in commit b7e7c044.
I have made the corresponding changes to the masked_variance code.

The frame marked as last_bipred at the encoder side is the frame right
before the source frame of BWDREF_FRAME, which was not used as a
reference. This CL is to add this type of frames to the reference frame
buffer and use them as reference for the coding of future frames. This
is a non-normative change.

A tiny gain is observed (lowres BDRate -0.016% in avg psnr). The main
target of this CL is to make it possible to have more flexible gf group
structure. For instance, LAST_BIPRED_UPDATE can be replaced by
LAST_UPDATE followed by an extra alt ref frame.
