ft_memcpy:

PARAMETERS
-/-

RETURN VALUE
The memcpy() function returns the original value of dst.

DESCRIPTION
The memcpy() function copies n bytes from memory area src to memory area dst. 
If dst and src overlap, behavior is undefined. Applications in which dst 
and src might overlap should use memmove(3) instead.

	   d  s   n = 5    -> s: src, d: dst
	result:
	   6789A89ABC

	0123456789ABC
	   |  |
	   s  d   n = 5    -> s: src, d: dst
	result:
	      34534BC

REMARK
Memory overlap not possible, use memmove for that
