calling a foreign function. This allows to use the unmodified libffi
library.
Remove most files from _ctypes/libffi_msvc, only two include files
stay (updated from _ctypes/libffi/...). Other files are used in the
cross-platform _ctypes/libffi directory.
Rewrite r80556: the thread test have to be executed just after the test on
libc_open() and so the test cannot be splitted in two functions (without
duplicating code, and I don't want to duplicate code).
* Split Test.test_open() in 2 functions: test_open() and test_thread_open()
* Skip test_open() and test_thread_open() if we are unable to find the C
library
* Skip test_thread_open() if thread support is disabled
* Use unittest.skipUnless(os.name == "nt", ...) on test_GetLastError()

Work in progress. 2 tests fail on x86/win32 because the stack
checking code in ffi_call_win32 is not yet implemented.
Remove most files from _ctypes/libffi_msvc, only two include files
stay (updated from _ctypes/libffi/...). Other files are used in the
cross-platform _ctypes/libffi directory.

On Windows, ctypes does no longer check the stack before and after
calling a foreign function.
This allows to use the unmodified libffi library.
........
ctypes maintains thread-local storage that has space for two error
numbers: private copies of the system 'errno' value and, on Windows,
the system error code accessed by the GetLastError() and
SetLastError() api functions.
Foreign functions created with CDLL(..., use_errno=True), when called,
swap the system 'errno' value with the private copy just before the
actual function call, and swapped again immediately afterwards. The
'use_errno' parameter defaults to False, in this case 'ctypes_errno'
is not touched.
On Windows, foreign functions created with CDLL(...,
use_last_error=True) or WinDLL(..., use_last_error=True) swap the
system LastError value with the ctypes private copy.
The values are also swapped immeditately before and after ctypes
callback functions are called, if the callbacks are constructed using
the new optional use_errno parameter set to True: CFUNCTYPE(...,
use_errno=TRUE) or WINFUNCTYPE(..., use_errno=True).
New ctypes functions are provided to access the ctypes private copies
from Python:
- ctypes.set_errno(value) and ctypes.set_last_error(value) store
'value' in the private copy and returns the previous value.
- ctypes.get_errno() and ctypes.get_last_error() returns the current
ctypes private copies value.
