  Issue #1798: Add ctypes calling convention that allows safe access of errno.

  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.

  Issue #1798: Add ctypes calling convention that allows safe access to
  errno (and LastError, on Windows).

  ctypes maintains a module-global, but thread-local, variable that
  contains an error number; called 'ctypes_errno' for this discussion.
  This variable is a private copy of the systems 'errno' value; the copy
  is swapped with the 'errno' variable on several occasions.

  Foreign functions created with CDLL(..., use_errno=True), when called,
  swap the values 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.

  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).

  Two new ctypes functions are provided to access the 'ctypes_errno'
  value from Python:

  - ctypes.set_errno(value) sets ctypes_errno to 'value', the previous
    ctypes_errno value is returned.

  - ctypes.get_errno() returns the current ctypes_errno value.

  ---

  On Windows, the same scheme is implemented for the error value which
  is managed by the GetLastError() and SetLastError() windows api calls.

  The ctypes functions are 'ctypes.set_last_error(value)' and
  'ctypes.get_last_error()', the CDLL and WinDLL optional parameter is
  named 'use_last_error', defaults to False.

  ---

  On Windows, TlsSetValue and TlsGetValue calls are used to provide
  thread local storage for the variables; ctypes compiled with __GNUC__
  uses __thread variables.
