Those functions were added to the C11 standard as an extension under the
name wcsnlen_s and strnlen_s. Also supported under that name in Windows.
Renaming avoids a possible name conflict with the posix functions of the
same name. Further this new name follows the pattern of names of the
other "secure" functions.
