main/libvirt: upgrade to 1.0.3

parent 3feb58c7

Subject: [PATCH] Fix missing error constants in libvirt python module
The previous change to the generator, changed too much - only
the functions are in 'virerror.c', the constants remained in
'virerror.h' which could not be renamed for API compat reasons.
Add a test case to sanity check the generated python bindings

Subject: [PATCH] complete virterror->virerror name change
Without these two string changes in generator.py, the
virGetLastError wrapper does not get created in
/usr/share/pyshared/libvirt.py. Noticed when running
tests with virt-install.

Subject: [PATCH 1/2] net: support set public ip range for forward mode nat
Support setting which public ip to use for NAT via attribute
address in subelement <nat> in <forward>:
...
<forward mode='nat'>
<address start='1.2.3.4' end='1.2.3.10'/>
</forward>
...
This will construct an iptables line using:
'-j SNAT --to-source <start>-<end>'
instead of:
'-j MASQUERADE'
