	DESCRIPTION :
	The function ft_strlcpy copies up to size - 1 characters from the given
	string src to the given string dst, nul-terminating the result.

	Note : space for the terminating \0 character must be included in dstsize.

	RETURN VALUE :
	The total length of the string that it tried to create : the length of
	src, with the goal to facilitate truncaction detection.
