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.

Bug #1651235 : When a tuple was passed to a ctypes function call,

parameters to function calls.

Remove the special casing of Py_None when converting the return value

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.
