[libvirt] [PATCH v2 0/2] network: Bring netdevs online later

[Matthew Rosato]

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 for v2:
 * Ping for comments, esp. on patch #2.
 * Moved @flags operand of virNetDevMacVLanCreateWithVPortProfile to the 
   end of the operand list.
 * Minor changes based on comments by Martin Kletzander.
 * Added detail to patch #2 commit message.  
 * Martin suggested that I replace various ? operations with if/else 
   statements, but I ended up leaving them alone as they were being used 
   to conditionally assign values to constant fields.
 * I left the contents of qemu_interface as-is, rather than collapsing 
   them into non-qemu-specific functions, in order to keep Makefile linkage
   consistent & happy (needs to be part of QEMU_DRIVER_SOURCES).  Instead,
   incorporated copyright suggestions from previous comments.  Martin, if
   you feel strongly about not having these new functions in a qemu-specific
   part, feel free to comment.    

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.
