Libvirt commit <95f5ac9ae52455e9da47afc95fa31c9456ac27ae> changed the
VIR_DOMAIN_QEMU_AGENT_COMMAND_* enum values to use different enum values
instead of direct numbers. We need to translate it back.

The virNetworkPort class is passed both the virNetwork parent
python class and the virNetworkPort C object. This needs special
handling in the generator, similar to how virDomainSnapshots are
dealt with.

This binding allows to query the AMD's SEV firmware for various platform
specific things, like a PDH certificate and a certificate chain to
establish a trusted connection with the firmware. Because the API uses
typed params, it's exempted from generation.

When using libvirt python you must never call the object
constructors directly, as these are expecting to be passed
a wrapped C object. For example
import libvirt
c = libvirt.virConnect("qemu:///system")
c.listAllDomains()
will mysteriously segfault. With this change the user now
gets an slightly more helpful error

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

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.

Add support for the libvirt_virDomainGetIOThreadsInfo method. This
code mostly follows the libvirt_virDomainGetVcpuPinInfo method, but
also takes some from the libvirt_virNodeGetCPUMap method with respect
to building the cpumap into the returned tuple rather than two separate
tuples which vcpu pinning generates
Assuming two domains, one with IOThreads defined (eg, 'iothr-gst') and
one without ('noiothr-gst'), execute the following in an 'iothr.py' file:
import libvirt
con=libvirt.open("qemu:///system")
dom=con.lookupByName('iothr-gst')
print dom.ioThreadsInfo()
dom2=con.lookupByName('noiothr-gst')
print dom2.ioThreadsInfo()
$ python iothr.py
[(1, [False, False, True, False]), (2, [False, False, False, True]), (3, [True, True, True, True])]
[]

In some cases, it is very easy for downstream distros to backport
enum values without requiring a .so bump. Keying the conditional
code off of the upstream version where the enum value was added
is not ideal, because downstream then has to patch that the feature
is available in their build that still reports an earlier version
number. For example, if RHEL 7 backports events from 1.2.11 into
a build based on 1.2.8, building the python bindings would warn:
libvirt-override.c: In function ‘libvirt_virConnectDomainEventRegisterAny’:
libvirt-override.c:6653:5: warning: enumeration value ‘VIR_DOMAIN_EVENT_ID_TUNABLE’ not handled in switch [-Wswitch]
switch ((virDomainEventID) eventID) {
^
libvirt-override.c:6653:5: warning: enumeration value ‘VIR_DOMAIN_EVENT_ID_AGENT_LIFECYCLE’ not handled in switch [-Wswitch]
The solution is simple - use feature-based probes instead of
version probes. Since we already scrape the XML API document of
whatever libvirt build we are binding, and that XML already
documents any downstream enum additions, we can use those as the
features for gating conditional compilation.
* generator.py (enum): Track event id names.
(buildStubs): Output define wrappers for events.
* libvirt-override.c
(libvirt_virConnectDomainEventBalloonChangeCallback)
(libvirt_virConnectDomainEventPMSuspendDiskCallback)

This returns the raw C pointer to the underlying object, eg:
conn = libvirt.open(None)
print "0x%x" % conn.c_pointer() # returns virConnectPtr of the connection
dom = conn.lookupByName("test")
print "0x%x" % dom.c_pointer() # returns virDomainPtr of the domain
The reason behind this is to allow us to transparently pass Python dom
objects through the libguestfs Python API.
