[libvirt] [PATCH v1 07/31] virNetworkObjListExport: Pass virNetworkObjListPtr

[Michal Privoznik]

Instead of copying the whole object onto stack when calling the
function, just pass the pointer to the object and save up some
space on the stack. Moreover, this prepares the code to hide the
virNetworkObjList structure into network_conf.c and use accessors
only.
