[Libvir] [PATCH] Add Python binding for virGetVersion

[Richard W.M. Jones]

This patch adds a Python binding for the virGetVersion call (called 
libvirt.getVersion).

$ python
Python 2.4.4 (#1, Oct 23 2006, 13:58:18)
[GCC 4.1.1 20061011 (Red Hat 4.1.1-30)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> import libvirt;
 >>> libvirt.getVersion (None);
(2002, 3000001)
 >>> libvirt.getVersion ("QEMU");
(2002, 2002)

It also gives you a way to detect if a particular driver is compiled in, 
which I guess could be quite useful:

 >>> libvirt.getVersion ("not_here");
libvir: error : no support for hypervisor
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File "/home/rjones/local/lib/python2.4/site-packages/libvirt.py", 
line 95, in getVersion
     if ret is None: raise libvirtError ("virGetVersion() failed")
libvirt.libvirtError: virGetVersion() failed no support for hypervisor

Rich.
