Added API information for the PyCallIter_*() and PySeqIter_*() functions.
Added signatures for some new PyType_*() functions.

+\subsection{Iterator Objects \label{iterator-objects}}
+
+Python provides two general-purpose iterator objects. The first, a
+sequence iterator, works with an arbitrary sequence supporting the
+\method{__getitem__()} method. The second works with a callable
+object and a sentinel value, calling the callable for each item in the
+sequence, and ending the iteration when the sentinel value is
+returned.
+
+\begin{cvardesc}{PyTypeObject}{PySeqIter_Type}
+ Type object for iterator objects returned by
+ \cfunction{PySeqIter_New()} and the one-argument form of the
+ \function{iter()} built-in function for built-in sequence types.
+\end{cvardesc}
+
+\begin{cfuncdesc}{int}{PySeqIter_Check}{op}
+ Return true if the type of \var{op} is \cdata{PySeqIter_Type}.
+\end{cfuncdesc}
+
+\begin{cfuncdesc}{PyObject*}{PySeqIter_New}{PyObject *seq}
+ Return an iterator that works with a general sequence object,
+ \var{seq}. The iteration ends when the sequence raises
+ \exception{IndexError} for the subscripting operation.

+ any Python callable object that can be called with no parameters;
+ each call to it should return the next item in the iteration. When
+ \var{callable} returns a value equal to \var{sentinel}, the
