[ft] Standard Library Dependencies in freetype-2.3.7

[Mickey Gabel]

I am trying to use a customized FT2 build for an embedded system, where 
memcpy does not exist. In fact, most of the standard library is not there.
If I understand correctly, the right way to do this is to replace 
functions in ftstdlib.h (or use another file as replacement TO 
ftstdlib.h), is that right?

Using the latest stable release (2.3.7), I can see that FT2 makes some 
direct calls to memcpy instead of ft_memcpy.
For example, see ftsmooth.c line 297.
Is this a bug? I shouldn't have to change ftsmooth.c, right?

Also, I am concerned about the use of setjmp/longjmp. Is there a way to 
not use it? Or at least use FT2 in a such a way that those functions are 
never called?
