* changes:
picture_csp_enc.c: remove SafeInitSharpYuv
sharpyuv: prefer webp/types.h
sharpyuv,SharpYuvInit: add mutex protection when available
sharyuv_{neon,sse2}.c: merge WEBP_USE_* sections
add a few missing <stddef.h> includes for NULL
sharpyuv.h: remove <inttypes.h>
this provides better compatibility for older Visual Studio versions;
stdint.h is a part of C99.
this is consistent with the core libwebp library:
8fbb9188 prefer webp/types.h over stdint.h

move WEBP_EXTERN definition from Makefile.vc to webp/types.h using the
existing WEBP_DLL define to control its declaration to
__declspec(dllexport); the same is done for SHARPYUV_EXTERN
Change-Id: Iecea360305bdd19a878255470a00b9dcc344c730
this is similar to WEBP_DSP_INIT and avoids the potential for a race in
initializing the function pointers and gamma table

this hasn't been needed since:
93c54371 sharpyuv: add support for 10/12/16 bit rgb and 10/12 bit yuv.

Headers are installed in a "sharpyuv" subdirectory of the webp
dir, e.g. /usr/local/include/webp/sharpyuv/
Remove unnecessary dependency from sharpyuv to webp/types.h
Add SHARPYUV_EXTERN so that only symbols meant to be public
are exported.
Sharpyuv users can use the library with:
find_package(WebP)
if(TARGET WebP::sharpyuv)
# ... use WebP::sharpyuv
endif()

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

- 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
Remove unused constants.
Use ALL_CAPS for defines and kCamelCase for static const values.
Change some defines into static constants if they are not used in array sizes.

under some versions of visual studio:
sharpyuv\sharpyuv_csp.c(43): warning C4244: '=': conversion from 'int' to
'float', possible loss of data
sharpyuv\sharpyuv_csp.c(35): warning C4244: 'initializing': conversion from
'int' to 'float', possible loss of data

It's self contained apart from a dependency on src/webp/types.h and src/dsp/cpu.h
For now it's only set up as an internal library, not an installable one.
Webp doesn't depend on it yet, the code is only duplicated.
