Mark internal wchar functions with attribute_hidden [BZ #18822]
Mark internal wchar functions with attribute_hidden to allow direct access within libc.so and libc.a without using GOT nor PLT. [BZ #18822] * include/wchar.h (__wcsnlen): Add attribute_hidden. (__wcscat): Likewise. (__btowc): Likewise. (__wcrtomb): Likewise. (__mbsrtowcs): Likewise. (__wcsrtombs): Likewise. (__mbsnrtowcs): Likewise. (__wcsnrtombs): Likewise. (__wcsncpy): Likewise. (__wcpncpy): Likewise. (__wmemcpy): Likewise. (__wmempcpy): Likewise. (__wmemmove): Likewise. (__wcschrnul): Likewise. (__vfwscanf): Likewise. (__vswprintf): Likewise. (__fwprintf): Likewise. (__vfwprintf): Likewise.
