python: Expose blockPeek and memoryPeek in Python binding

Browse Source 
A simple example to show how to use it:

\#! /usr/bin/python

import os
import sys
import libvirt

disk = "/var/lib/libvirt/images/test.img"

conn = libvirt.open(None)
dom = conn.lookupByName('test')

mem_contents = dom.memoryPeek(0, 32, libvirt.VIR_MEMORY_VIRTUAL);
sys.stdout.write(mem_contents)

% python test.py | hexdump
