	1- Get the len of the source for the malloc

	4- Return the new string

	[Description ft_strlen]
		1- Iterate the string, and return the counter(i)

	[Description ft_strlcpy]
		1- Check if parameter lend_dst its 0 or negative
			- If its return the len of str
		2- Iterate while source exist and the counter its less to len_dst
		3- Every iteration copy the source in the destination
		4- When the iteration its over close the string
		5- Return the len of the source
