[issue6259] ctypes pointer arithmetic

[Amaury Forgeot d'Arc]

I like this feature. Some comments:

- tests...

- unsupported operand types should return Py_NotImplemented.

- gcc supports pointer arithmetic with void*:
  http://gcc.gnu.org/onlinedocs/gcc/Pointer-Arith.html
  Could ctypes do the same?

- Some operations are not allowed. If p1 and p2 are ctypes pointers,
  "p1 -= p2" will not work - but it's not a common usage.
  However, "p1 + 1" and "p1 - 1" seem very useful, and should be supported.
