patch which do not work with Python 3.

ChangeLog

2014-08-05  Siva Chandra Reddy  <sivachandra@google.com>

    gdb/

        * python/lib/gdb/command/xmethods.py (set_xm_status1): Use the
        'items' methods instead of 'iteritems' method on dictionaries.

    gdb/testsuite/

        * gdb.python/py-xmethods.py (A_getarrayind)
        (E_method_char_worker.__call__, E_method_int_worker.__call__):
        Use 'print' with function call syntax.
        (E_method_matcher.match): Fix tab vs space indentation mixup.
