dcb3c382ac Somewhat-preliminary slice-object and extended slicing support for ctypes. 
The exact behaviour of omitted and negative indices for the Pointer type may
need a closer look (especially as it's subtly different from simple slices)
but there's time yet before 2.6, and not enough before 3.0a1 :-)

1421b00162 Repair COMError. Since exceptions are new style classes now, setting 
the methods and docstring after the type creation does not work, they
must be in the dictionary before creating the type.

68bb9a1418 When accessing the .value attribute of a c_wchar_p instance, and the 
instance does not point to a valid wchar_t zero-terminated string,
raise a ValueError.  c_char_p does this already.

The ValueError message now contains the correct pointer address.

2456a3c02a Bug #1651235: When a tuple was passed to a ctypes function call, 
Python would crash instead of raising an error.

The crash was caused by a section of code that should have been
removed long ago, at that time ctypes had other ways to pass
parameters to function calls.

d2ea4a2584 ctypes callback functions only support 'fundamental' result types. 
Check this and raise an error when something else is used - before
this change ctypes would hang or crash when such a callback was
called.  This is a partial fix for #1574584.

Will backport to release25-maint.

0b21b43d49 Add asserts to check for 'impossible' NULL values, with comments. 
In one place where I'n not 1000% sure about the non-NULL, raise
a RuntimeError for safety.

This should fix the klocwork issues that Neal sent me.  If so,
it should be applied to the release25-maint branch also.

b4a0cf17c4 Remove the special casing of Py_None when converting the return value 
of the Python part of a callback function to C.  If it cannot be
converted, call PyErr_WriteUnraisable with the exception we got.
Before, arbitrary data has been passed to the calling C code in this
case.

(I'm not really sure the NEWS entry is understandable, but I cannot
find better words)

b0aa98fd4f The __repr__ method of a NULL py_object does no longer raise an 
exception.  Remove a stray '?' character from the exception text
when the value is retrieved of such an object.

Includes tests.

d32e616722 Add commented assert statements to check that the result of 
PyObject_stgdict() and PyType_stgdict() calls are non-NULL before
dereferencing the result.  Hopefully this fixes what klocwork is
complaining about.

Fix a few other nits as well.

867200483b Apply the patch #1532975 plus ideas from the patch #1533481. 
ctypes instances no longer have the internal and undocumented
'_as_parameter_' attribute which was used to adapt them to foreign
function calls; this mechanism is replaced by a function pointer in
the type's stgdict.

In the 'from_param' class methods, try the _as_parameter_ attribute if
other conversions are not possible.

This makes the documented _as_parameter_ mechanism work as intended.

Change the ctypes version number to 1.0.1.
