<string.h> and wcschr, wcspbrk, wcsrchr, wmemchr, and wcsstr from <wchar.h> to provide a const-correct overload set even when the underlying C library does not. This change adds a new macro, _LIBCPP_PREFERRED_OVERLOAD, which (if defined) specifies that a given overload is a better match than an otherwise equally good function declaration without the overload. This is implemented in modern versions of Clang via __attribute__((enable_if)), and not elsewhere. We use this new macro to define overloads in the global namespace for these functions that displace the overloads provided by the C library, unless we believe the C library is already providing the correct signatures. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@260337 91177308-0d34-0410-b5e6-96231b3b80d8
