* Fixed bpo-29565: Corrected ctypes passing of large structs by value.

Added code and test to check that when a structure passed by value
is large enough to need to be passed by reference, a copy of the
original structure is passed. The callee updates the passed-in value,
and the test verifies that the caller's copy is unchanged. A similar
change was also added to the test added for bpo-20160 (that test was
passing, but the changes should guard against regressions).

* Reverted unintended whitespace changes.

These numbers were already 64bit if available until the relevant
preprocessor macro was renamed. This change affects Stackless structures
PyStacklessState and PyCStackObject. Extension authors usually don't
access them directly.
