SF feature request #686323: Minor array module enhancements

array.extend() now accepts iterable arguments implements as a series
of appends.  Besides being a user convenience and matching the behavior
for lists, this the saves memory and cycles that would be used to
create a temporary array object.

\begin{methoddesc}[array]{extend}{a}
Append array items from \var{a} to the end of the array. The two
arrays must have \emph{exactly} the same type code; if not,
\exception{TypeError} will be raised.
\begin{methoddesc}[array]{extend}{iterable}
Append items from \var{iterable} to the end of the array. If
\var{iterable} is another array, it must have \emph{exactly} the same
type code; if not, \exception{TypeError} will be raised. If
\var{iterable} is not an array, it must be iterable and its
elements must be the right type to be appended to the array.
