* python/py-framefilter.c (py_print_frame): Remove usage of
	PyString_AsString.  Use python_string_to_host_string instead.
	Refactor function to work with a string as a new allocation
	instead of a pointer.
	(py_print_frame): Ditto.
	* python/lib/gdb/frames.py (return_list): Cain iterators together
	instead of adding them as a list.
	(_sort_list): Call return_list, and remove duplicate code.
	(execute_frame_filters): Convert iterator to a list with list().
	* python/lib/gdb/command/frame_filters.py
	(SetFrameFilterPriority._set_filter_priority): Convert priority
	attribute to an integer.
	* python/lib/gdb/FrameIterator.py (FrameIterator.next): Define
	wrapper function __next__.
	* python/lib/gdb/FrameDecorator.py: If basestring not defined,
	define as "str".

2013-08-29  Phil Muldoon  <pmuldoon@redhat.com>

	* gdb.python/py-framefilter.py (FrameFilter.filter): Check
	itertools for imap attribute.  Otherwise use map().
	(ElidingIterator): Define wrapper function __next__.
	* gdb.python/py-framefilter-mi.exp: Do not use execfile,
	use exec (open (read ())) instead.
	* gdb.python/py-framefilter.exp: Ditto.
	* gdb.python/py-arch.exp: Update print based test to Python 3.x
	compliance.
