LGTM.
Oh, I'm sorry, I didn't notice that each additional tested size requires to write a long C code in _ctypes_test.c. IMHO it's not worth it and adds too much maintenance burden. I was concerned about a special case for size=16 bytes, but again, I don't think that it's worth it.
Would you mind to remove tests for 11..20, so only test 1..10? So we cover all special cases on 64-bit + size 9 and size 10 -- just in case.

@vladima: Would you mind to check if the issue exists upstream? https://github.com/libffi/libffi/tree/master/src |

@vstinner code upstream is a bit reshaped but at glance this issue is already fixed. |

python/cpython#9258 changed callproc to use functions from the internal libffi which we don't use. Just copy the functions into callproc directly instead.

Per MSDN: Return values:
Effectively if size of struct is not 1, 2, 4 or 8 bytes - caller needs to allocate a memory for the result and pass a pointer as a first argument.
