This change makes it easier to free allocated object especially for
python objects. We can benefit from the fact, that if you call
Py_DECREF on any python object it will also remove reference for all
assigned object to the root object. For example, calling Py_DECREF on
dict will also remove reference recursively on all elements in that
dictionary. Our job is then just call Py_DECREF on the root element and
don't care about anything else.

To insert Py_None into some other python object like dict or tuple, you
need to increase reference to the Py_None. We have a macro to do that.

In case of error without setting an python exception we need to return
a correct python object. For functions that returns anything else than
a number the return value is 'None', otherwise it's '-1'.

There is a rule, python API fails, it also in those cases sets an
exception. We should follow those rules and in those cases return NULL.

if build libvirt-python with some old xml lib (python-pyxml),
build will fail and error like this:
File "generator.py", line 139, in start
if "string" in attrs:
File "/usr/local/lib/python2.7/site-packages/_xmlplus/sax/xmlreader.py" \
, line 316, in __getitem__
return self._attrs[name]
KeyError: 0
This is an old issue and have been mentioned in commit 3ae0a76d.
There is no __contains__ in class AttributesImpl, python will use
__getitem__ in this place, so we will get error.
Let's use 'YYY in XXX.keys()' to avoid this issue.

libvirt_virDomainGetSecurityLabelList called PyList_Append without
checking its return value. While looking at it I noticed the function
did not properly check several other return values either so I fixed
them all.

So, this is an exercise to show libvirt capabilities. Firstly, for
each host NUMA nodes some statistics are printed out, i.e. total
memory and free memory. Then, for each running domain, that has memory
strictly bound to certain host nodes, a small statistics of how much
memory it takes is printed out too. For instance:
# ./examples/nodestats.py
NUMA stats
NUMA nodes: 0 1 2 3
MemTotal: 3950 3967 3937 3943
MemFree: 66 56 42 41
Domain 'fedora':
Overall memory: 1536 MiB
Domain 'fedora22':
Overall memory: 2048 MiB
Domain 'fedora21':
Overall memory: 1024 MiB nodes 0-1
Node 0: 1024 MiB nodes 0-1
Domain 'gentoo':
Overall memory: 4096 MiB nodes 0-3
Node 0: 1024 MiB nodes 0
Node 1: 1024 MiB nodes 1
Node 2: 1024 MiB nodes 2
Node 3: 1024 MiB nodes 3
We can see 4 host NUMA nodes, all of them having roughly 4GB of RAM.
Yeah, all of them has nearly all the memory consumed. Then, there are
four domains running. For instance, domain 'fedora' has 1.5GB memory
which is not pinned onto any specific host NUMA node. Domain 'gentoo' on
the other hand has 4GB memory and has 4 NUMA nodes which are pinned 1:1
to host nodes.

This reverts commit 751e016f09.
Since Admin API was deferred for a release and the minor version bump
didn't happen, it must not happen in libvirt-python either, for
compatibility reasons.
Since the background for Admin API is merged upstream, we are bumping
the minor release version as discussed previously

The generated AUTHORS file contains many duplicates. If an author
has N commits, there will be N entries for the author in AUTHORS.
Check if an author already exists in the list before appending.
While at it, add a .mailmap (derived from libivrt's .mailmap) to
futher tidy the generated AUTHORS list.
In order to achieve reproducible builds[0] we want the items within
enums always generated in the same order so sort on both items in the
tuple.

This example allows to use the guest agent event and metadata to track
vCPU count set via the guest agent (agent-based onlining/offlining) and
keep it persistent accross domain restarts.
The daemon listens for the agent lifecycle event, and if it's received
it looks into doman's metadata to see whether a desired count was set
and issues the guest agent command.

When called without parameters, sanitytest.py doesn't touch sys.path and
locates itself the patch to the libvirt-api.xml file using pkg-config.
This change makes possible to run sanitytest.py from tox.
