        Sanitize web fonts using the OTS library
        https://bugs.webkit.org/show_bug.cgi?id=31106

        Add support for OpenType sanitizer (OTS). It parses OpenType files (from @font-face)
        and attempts to validate and sanitize them. We hope this reduces the attack surface
        of the system font libraries.

        * WebCore.gyp/WebCore.gyp: Added dependency to (chromium_src_dir)/third_party/ots/ library.
        * WebCore.gypi: Added new files below.
        * WebCore.xcodeproj/project.pbxproj: Ditto.
        * platform/graphics/chromium/FontCustomPlatformData.cpp: Validate and transcode a web font.
        (WebCore::createFontCustomPlatformData):
        * platform/graphics/mac/FontCustomPlatformData.cpp: Ditto.
        (WebCore::createFontCustomPlatformData):
        * platform/graphics/opentype/OpenTypeSanitizer.cpp: Added.
        (WebCore::OpenTypeSanitizer::sanitize):
        * platform/graphics/opentype/OpenTypeSanitizer.h: Added.
