This adds a binding for the virConnectOpenAuth() api in the python

Opps, this wasn't mean to sneak in this patch. This fixes a wierd crash
case which happens occassionally when libvirtd starts up. For me it only
ever happens if i run configure with a --prefix pointing to a non-default
value, eg /home/berrange/src/xen/libvirt
Interestingly valgrind fails to catch this off-by-1 flaw
