[issue13250] ctypes: reference leak in POINTER code

[Meador Inge]

New submission from Meador Inge <meadori at gmail.com>:

While implementing a patch for issue13096 I found a reference leak in 'ctypes'.  I couldn't find the cause immediately, but it can be 
reproduced by applying the attached patch and running:

[meadori at motherbrain cpython]$ ./python -m test -R : test_ctypes
[1/1] test_ctypes
beginning 9 repetitions
123456789
.........
test_ctypes leaked [51, 51, 51, 51] references, sum=204
1 test failed:
    test_ctypes
[174347 refs]
