[libvirt] [PATCH 0/2] (for 1.2.7) network: Bring netdevs online later

The following patchset introduces code to defer setting netdevs online
(and therefore registering MACs) until right before beginning guest 
CPU execution.  The first patch introduces some infrastructure changes
in preparation of the actual function added in the 2nd patch.  

Associated BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1081461

Changes since RFC:
 * Add a separate patch to introduce a flags field for macvlan/macvtap 
   creation.
 * Use macvlan/tap IFUP flags to skip virNetDevSetOnline (for qemu only).  
 * Add hotplug support.
 * For macvlan, save the current virNetDevVPortProfileOp in virDomainNetDef
   during qemuPhysIfaceConnect.  As Laine mentioned, could use this field in
   a future patch to eliminate passing virNetDevVPortProfileOp everywhere.  
 * Add qemu_interface.c and qemu_interface.h to encapsulate new functions.
