freeze break request: fix pyatspi.getState().getStates()

[Mike Gorse <mgorse novell com>]

AT-SPI has a method to return the list of states contained in a state set 
as an array, but this sometimes fails with pyatspi on 64-bit architectures 
because of what I think is a bug in pygi.  In any case, pygi is copying an 
argument from an array (an int in this case) and later assuming that it 
has a valid long value, so it might read eight bytes where only four were 
initialized.  I've filed the issue as BGO#646581.  I would like to apply 
the attached patch to pyatspi for the time being; it works around the 
issue by not making the problematic C call.

Thanks,
-Mike
