* string/bits/string3.h (memcpy, memmove, mempcpy, memset, bcopy,
bzero, strcpy, stpcpy, strncpy, strcat, strncat): Use
__extern_always_inline functions unconditionally, drop macros.
* misc/sys/cdefs.h (__REDIRECT_LDBL, __REDIRECT_NTH_LDBL): New macros.
* wcsmbs/bits/wchar2.h (__swprintf_alias, __vswprintf_alias): Use
__REDIRECT_NTH_LDBL macro rather than __REDIRECT_NTH.
