\brief Size-limited null-terminating string copy.

This is similar to \a strncpy, with two important differences:
- the destination buffer will \b always be null-terminated
- the destination buffer is not filled with zeros past the copied string length
These differences make it slightly more efficient, and safer to use since it will
not leave the destination buffer unterminated. There is no need to pass an artificially
reduced buffer size to this function (unlike \a strncpy), and the buffer does not need
to be initialized to zeroes prior to calling this function.
