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.

when building for windows with _UNICODE defined
unicode_gif.h|49 col 3| warning: ISO C90 forbids mixed declarations and

... since no guarantee of Huffman coding can be introduced at decoding
time and encoding didn't actually use Huffman coding in the first place

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.
Change-Id: Ic1c78c8f8fae528395fa46a74f717f47cb13098e
* changes:
CMake: add src to webpinfo includes
CMake: add WEBP_BUILD_WEBPINFO to list of checks for exampleutil
CMake: add WEBP_BUILD_WEBPMUX to list of checks for exampleutil
CMake: link imageioutil to exampleutil after defined
WEBP_DEP_LIBRARIES: use Threads::Threads

- Remove SHALF constant so that we get back the original value when
calling UpScale then downscale with rounding
- Make the linear->gamma precomputed table bigger (8 bits rather than 5)
- Round values in kLinearToGammaTabS
Change-Id: Ic9634d32cf93de321d2f6e9e4cad7f156d8d07df
- pic->picture in public header
- match implementation to declaration in PictureImport, WebPPictureRescale, WebpBlendAlpha

The forward transform subtracts the deltas, the inverse adds them.
