d395c81121 python: Fix emulatorpin API bindings
The addition of emulator pinning APIs didn't think of doing the right
job with python APIs for them. The default generator produced unusable
code for this.

This patch switches to proper code as in the case of domain Vcpu pining.
This change can be classified as a python API-breaker but in the state
the code was before I doubt anyone was able to use it successfully.

4b143ab231 python: fix bindings that don't raise an exception
For example:
 >>> dom.memoryStats()
 libvir: QEMU Driver error : Requested operation is not valid:\
         domain is not running

There are six such python API functions like so.
The root reason is that generator.py script checks the type of return
value of a python stub function defined in libvirt-api.xml or
libvirt-override-api.xml to see whether to add the raise clause or not
in python wrapper code in libvirt.py.

The type of return value is supposed to be C types.
For those stub functions which return python non-integer data type like
string, list, tuple, dictionary, the existing type in functions varies
from each other which leads problem like this.

Currently, in generator.py, it maintains a buggy whitelist for stub functions
returning a list type. I think it is easy to forget adding new function name
in the whitelist.

This patch makes the value of type consistent with C type "char *"
in libvirt-override-api.xml. For python, any of types could be printed
as string, so I choose "char *" in this case. And the comment in xml
could explain it when adding new function definition.

      <function name='virNodeGetCPUStats' file='python'>
        ...
 -      <return type='virNodeCPUStats' info='...'/>
 +      <return type='char *' info='...'/>
        ...
      </function>

857f116871 virNodeGetCPUMap: Add python binding
Added a method getCPUMap to virConnect.
It can be used as follows:

import libvirt
import sys
import os

conn = libvirt.openReadOnly(None)
if conn == None:
    print 'Failed to open connection to the hypervisor'
    sys.exit(1)

try:
    (cpus, cpumap, online) = conn.getCPUMap(0)
except:
    print 'Failed to extract the node cpu map information'
    sys.exit(1)

print 'CPUs total %d, online %d' % (cpus, online)
print 'CPU map %s' % str(cpumap)

del conn
print "OK"

sys.exit(0)

bd34cc8c45 python: add API exports for virConnectListAllDomains()
This patch adds export of the new API function
virConnectListAllDomains() to the libvirt-python bindings. The
virConnect object now has method "listAllDomains" that takes only the
flags parameter and returns a python list of virDomain object
corresponding to virDomainPtrs returned by the underlying api.

The implementation is done manually as the generator does not support
wrapping list of virDomainPtrs into virDomain objects.

ae3315aa4a python: Fix problems of virDomain{Set, Get}BlockIoTune bindings
The parameter 'params' is useless for virDomainGetBlockIoTune API,
and the return value type should be a virTypedParameterPtr but not
integer. And "PyArg_ParseTuple" in functions
libvirt_virDomain{Set,Get}BlockIoTune misses format unit for "format"
argument.

* libvirt-override-api.xml: Remove useless the parameter 'params'
from virDomainGetBlockIoTune API, and change return value type from
integer to virTypedParameterPtr.

* python/libvirt-override.c: Add the missed format units.

8749256d0b Fix up the python bindings for snapshotting.
This involved a few fixes.  To start with,
an virDomainSnapshot object is really tied to a
domain, not a connection, so we have to generate
a slightly different object so that we can get
at self._dom for the object.

Next, we had to "dummy" up an override piece of
XML with a bogus argument that the function doesn't
actually take.  That's so that the generator places
virDomainRevertToSnapshot underneath the correct
class (namely, the virDomain class).

Finally, we had to hand-implement the
virDomainRevertToSnapshot implementation, ignoring the
bogus pointer we are being passed.

With all of this in place, I was able to successfully
take a snapshot and revert to it using only the
Python bindings.
