Eric Blake 63bfc59823 python: don't mask libvirt errors 
A user reported this crash when using python bindings:

  File "/home/nox/workspace/NOX/src/NOX/hooks.py", line 134, in trigger
    hook.trigger(event)
  File "/home/nox/workspace/NOX/src/NOX/hooks.py", line 33, in trigger
    self.handlers[event]()
  File "/home/nox/workspace/NOX/hooks/volatility.py", line 81, in memory_dump
    for block in Memory(self.ctx):
  File "/home/see/workspace/NOX/src/NOX/lib/libtools.py", line 179, in next
    libvirt.VIR_MEMORY_PHYSICAL)
  File "/usr/lib/python2.7/dist-packages/libvirt.py", line 1759, in memoryPeek
    ret = libvirtmod.virDomainMemoryPeek(self._o, start, size, flags)
SystemError: error return without exception set

In the python bindings, returning NULL makes python think an
exception was thrown, while returning the None object lets the
wrappers know that a libvirt error exists.

Reported by Nox DaFox, fix suggested by Dan Berrange.

* python/libvirt-override.c (libvirt_virDomainBlockPeek)
(libvirt_virDomainMemoryPeek): Return python's None object, so
wrapper knows to check libvirt error.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
