Maryla
1124ff662d Add -fvisibility=hidden flag in CMakeLists.
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

e15b356014 add WEBP_MSAN
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.

ec9e782a35 sharpyuv: remove minimum image size from sharpyuv library
libwebp still has a size threshold of 4 pixels in picture_csp_enc.c
but the sharpyuv library itself can handle any image size.
