  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.

  Move assert to after NULL check, otherwise we deref NULL in the assert.

  Anonymous structure fields that have a bit-width specified did not work,
  and they gave a strange error message from PyArg_ParseTuple:
      function takes exactly 2 arguments (3 given).

  With tests.

  The cast function did not accept c_char_p or c_wchar_p instances
  as first argument, and failed with a 'bad argument to internal function'
  error message.

  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.

(This had to be done with the command line:

  svnmerge init -r 1:51333 -F c:\svn\trunk\Modules\_ctypes

because svnmerge isn't able to deduce the branch point r51333 and the
HEAD URL automatically in a subdirectory.)

Merge rev 52377 from trunk:

newIobject():  repaired incorrect cast to quiet MSVC warning.

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.
