First, BuildHuffmanTable is called to check if the data is valid.
If it is and the table is not big enough, more memory is allocated.
This will make sure that valid (but unoptimized because of unbalanced
codes) streams are still decodable.

(cherry picked from commit 902bc91903)
(cherry picked from commit 2af26267cd)
WEBP_REDUCE_SIZE was introduced to bring down the library size by
removing cropping and scaling support. Previously WebPPictureView() was
only used with these two, but in
ec178f2c Add progress hook granularity in lossless
an additional use was added in VP8LEncodeStream() when extra side
configurations are used in crunch mode (-mt, quality == 100 & method ==
6 or quality >= 75 & method == 5 with a palette present currently).
WebPPictureView() and, for coherency, WebPPictureIsView() are
restored in this configuration to avoid affecting the general encode
path.
Previously WebPPictureView() was assumed to always succeed in these
cases which could result in crashes with WEBP_REDUCE_SIZE defined.

This fixes incorrect character display in the file name
in e.g., stats output from cwebp.exe in visual studio builds.
In mingw further changes will be needed as using %s in wfprintf() for
wchar_t pointers is a Microsoft extension that doesn't seem to be
supported with gcc -fms-extensions. %ls works, but will require updating
format strings and wrapping concatenations with TO_W_CHAR() as visual
studio will reject merging string constants of different width.

This way, only functions marked with WEBP_EXTERN get exposed by the library.
This flag is already set in other build configs: configure.ac, makefile.unix,
Android.mk

and use it to suppress a false positive related to data that passes
through RGBA32PackedToPlanar_16b_SSE41(). Current versions (tested with
clang 13.0.1, using -O0 and the build from oss-fuzz of enc_dec_fuzzer)
model shuffles incorrectly reporting use of uninitialized
data related to the alpha change that's removed when converting to YUV.
valgrind behaves correctly, however.

libwebp still has a size threshold of 4 pixels in picture_csp_enc.c
but the sharpyuv library itself can handle any image size.

CMake: link imageioutil to exampleutil after defined
WEBP_DEP_LIBRARIES: use Threads::Threads

calling UpScale then downscale with rounding
- Make the linear->gamma precomputed table bigger (8 bits rather than 5)
- Round values in kLinearToGammaTabS
