[webkit-dev] Rename wtf/unicode/UTF8.h

wtf/unicode/UTF8.h is conflicting with ICU header in MSVC builds. I'd like to rename wtf/unicode/UTF8.h to wtf/unicode/WTFUTF8.h. Any suggestion? Here is ICU's #include "unicode/utf8.h" which happens to include wtf/unicode/UTF8.h https://github.com/unicode-org/icu/blob/master/icu4c/source/common/unicode/u... Here is MSVC quoted form #include behavior documented. https://msdn.microsoft.com/en-us/library/36k2cdd4.aspx Bug 189693 – [Win][Clang] warning: #include resolved using non-portable Microsoft search rules as: ..\..\Source\WTF\wtf/unicode/utf8.h https://bugs.webkit.org/show_bug.cgi?id=189693 -- Fujii
