args - replacing destination strings with void pointers

As per David Gilbert's email:
On library functions like strcpy() where there is a destination
string, latrace -A ends up trying to print out the
destination buffer which may be completely invalid.

Maybe it's worth doing the same trick that ltrace does, and just
declare the destination parameters as void*

until we handle bad characters somehow, replacing
destination char pointers with void pointers
